2012 Toyota Tacoma Engine Problems

Your 2012 Tacoma may be stuck at a top speed of 45 MPH, with the check engine and traction control warning lights staying on. A dealer diagnosis found that your air injection pump needs to be replaced, which is related to a manufacturer service campaign (20TC01) that has since expired. Replacing the air injection pump should restore normal engine performance and turn off the warning lights.

MY 2012 TACOMA WARNING LIGHT 1) ENGINE AND 2 TRAC OFF WARNING LIGHT CAME ON AND LOST POWER GOING 65 MPH ON FREEWAY AND WOULD NOT GO OVER 25 MPH (DANGEROUS!). OBD-II SCANNER DISPLAYED ERROR CODE CHECK P2442 INDICATING FAULTY AIR INJECTION PUMPS AND/OR AIR SWITCHING VALVES. *TR

ON MY 2012 TACOMA THE CODE P2440 AND P2442 WHICH REPRESENT A STUCK OPEN VALVE IN THE SECONDARY AIR INJECTION SYSTEM. UPON MY RESEARCH INTO THIS ISSUE ON FORUMS I HAVE LEARNED THIS IS A COMMON PROBLEM WITH THE TOYOTA SYSTEMS PARTICULARLY THE 2012 TACOMA. THE COST OF THE PART IS ABOUT 400 TO 500 DOLLARS FOR THE VALVES AND ANOTHER 500 DOLLARS FOR THE SECONDARY AIR INJECTION PUMP. THE FAILURE WILL PLACE THE VEHICLE INTO A LIMP MODE AND HAS TO BE FIXED IN ORDER TO THE TRUCK TO KEEP ON GOOD WORKING CONDITION. IT SEEMS LIKE THIS ERROR HAS AFFECTED MANY TACOMA OWNERS. *TR

TWO DASHBOARD LIGHTS ILLUMINATED AT THE SAME TIME: THE CHECK ENGINE LIGHT AND THE TRAC OFF LIGHT. AT FIRST I REALLY DIDN'T NOTICE MUCH OF A DIFFERENCE BUT AFTER 2 DAYS I EXPERIENCED SIGNIFICANT POWER LOSS. I WOULD PULL OUT INTO TRAFFIC OK UNTIL ABOUT 20MPH THEN HAVE NO POWER. IT CRAWLED WHILE TRYING TO GET UP TO SPEED. I READ ON THE INTERNET THAT IF YOU DISCONNECT THE BATTERY AND OPEN THE GAS CAP THE LIGHTS WOULD GO OUT AND THE PROBLEM WOULD GO AWAY. I DID THIS AND IT WORKED; OR SO I THOUGHT. I THEN LEFT FOR AN HOUR TRIP (I KNOW DUMB) AND WITHIN 15 MINS THE LIGHTS CAME BACK ON AND I COULDN'T GET THE TRUCK OVER 60MPH ON A MAJOR HIGHWAY. I ACTUALLY STOPPED AT A REST STOP AND DISCONNECTED THE BATTERY AND REMOVED THE GAS CAP. AGAIN THIS SHUT OFF THE LIGHTS BUT ONLY FOR ABOUT 5 MINS. THEN THE POWER LOSS WAS BACK. TOOK TO MY LOCAL MECHANIC WHO I TRUST AND HE SAID IT WAS A KNOWN PROBLEM THAT WAS SOMETHING CALLED A TECHNICAL SERVICE BULLETIN BUT NOT YET A RECALL. APPARENTLY THE TUNDRA AND SEQUOIA ARE RECALLED FOR THIS PROBLEM BUT NOT THE TACOMA. I DON'T GET IT. I WAS TOLD TO KEEP MY RECEIPTS ($1,870.68) RIGHT AFTER CHRISTMAS THANK YOU, AND HOPEFULLY ONE DAY GET REIMBURSED IF IT BECOMES A RECALL. I CAN ONLY HOPE THIS IS A NO INTEREST INVESTMENT INTO MY FUTURE. *TR

FAILURE OF THE SECONDARY AIR INJECTION SYSTEM P2440 AND P2442, WHILE THE VEHICLE WAS MOVING ONTO A CITY STREET FROM A PARKING LOT. WHEN ACCELERATING IMMEDIATELY THERE WAS A DECREASE IN POWER AND THE CHECK ENGINE LIGHT ALONG WITH THE "TRAC OFF" LIGHT ILLUMINATING SIMULTANEOUSLY. THE VEHICLE HAS A NOW MAXIMUM SPEED OF AROUND 55 MPH AND EXTREMELY SLOW TO ACCELERATE BEING ALMOST DANGEROUS ON BUSIER ROADS. AFTER BEING CHECK OUT BY A THE DEALER IT WAS FOUND TO BE THE SECONDARY AIR INJECTION SYSTEM WHICH IS COVERED BY AN EXTENDED WARRANTY BUT PARTS ARE ON BACK-ORDER.

WHILE ON A ROAD TRIP I HAD MY CHECK ENGINE LIGHT COME ON WHILE ON THE HIGHWAY DUE TO DEFECTIVE SECONDARY INJECTION VALVES BEING STUCK CLOSED/OPEN. THE CODES I HAD FOR THIS ISSUE IS P2440 AND P2442. IN MY CASE THIS ISSUE MADE MY TRUCK GO INTO LIMP MODE WHICH IS OFTEN A LOSS OF POWER IN THE ENGINE AND SOMETIMES A RESTRICTION IN ONE'S ABILITY TO SHIFT THE TRUCK. LUCKILY THE HIGHWAY WAS NOT BUSY AT THE TIME THIS HAPPENED, BUT IF IT WERE I WOULD BELIEVE THAT IT WOULD BE A VERY UNSAFE THING TO HAPPEN GOING 70 MPH. THE PARTS DO HAVE AN EXTENDED WARRANTY UNTIL 2022 IF I REMEMBER RIGHT, BUT IT SEEMS LIKE TOYOTA IS NOT INTERESTED IN RECALLING THESE PARTS EVEN AFTER THEY HAVE KNOWN FOR MANY YEARS THAT THESE PARTS ARE DEFECTIVE. I HAVE DONE QUITE A BIT OF RESEARCH AND FOUND ISSUES WITH THESE PARTS GOING BACK TO 2013.

HAVING TROUBLE WITH MY VEHICLES SECONDARY AIR INJECTION SYSTEM, REPLACEMENT PARTS ARE SUPER EXPENSIVE AND HAVE SEEN MANY PEOPLE HAVE THE SAME ISSUE, SEEMS LIKE A NON-RELIABLE COMPONENT. ALWAYS GET THE FAULT CODES P2440 AND P2442. I STRONGLY BELEIVE THAT THIS IS A DEFECTIVE COMPONENT.

CIL AND TRAC ILLUMINATION WITH CODES P2440 AND P2442 CAUSED THE ENGINE TO GO TO LIMP MODE WITH LOSS OF POWER

KNOWN ISSUE WITH THE SECONDARY AIR VALVE. THROWS THE CODE P2442 VEHICLE GOES INTO SAFE MODE. DEALERSHIPS WANT ABOUT $2,000 TO FIX IT. RECOMMENDING THE FAN-BLOWER AS WILL TO DOUBLE THE AMOUNT. THIS IS KNOWN ISSUE FROM ALL THAT I HAVE READ AND THE DEALERSHIP THAT I PURCHASED IT FROM IN VA LAST YEAR DIDN'T MENTION THIS AT ALL OR OFFER ANY KIND OF WARRANTY TO COVER POTENTIAL ISSUES.

CHECK ENGINE LIGHT AND TRAC OFF LIGHT CAME ON. TRUCK WILL NOT EXCEED OVER 2500 RPM AND/OR REACH A SPEED OVER 25 MPH. NO TORQUE/POWER WHEN GAS PEDAL IS PRESSED, ESPESICIALLY WHEN TRAVELING UP STEEP TERRAIN. TOYOTA NEEDS TO ISSUE A RECALL ON THIS ISSUE.

THE CHECK ENG & TRAC OFF LIGHT CAME ON WHILE I WAS ON THE INTERSTATE AND ALMOST GOT STRUCK FROM THE VEHICLE BEHIND ME. MY TRUCK WENT INTO LIMP MODE & SLOWED DOWN TO 2500 RPMS & WOULDN'T GO ANY FASTER THAN 25 MPH!! THIS IS A HAZARD AS I HAVE READ OTHER COMPLAINTS ABOUT THIS HAPPENING TO OTHERS, IT IS A KNOWN ISSUE TO TOYOTA, THEY HAVE REPAIRED THE TUNDRA'S BUT SO FAR AM NOT SHOWING ANY RECALL ON THE TACOMA'S. ERROR P2442 SECONDARY AIR INJECTOR FAILURE. THIS IS THE 2ND TIME THIS HAS HAPPENED TO ME. SCARY! PLEASE BEWARE 2012 TACOMA OWNERS! MERRY CHRISTMAS TO ME! $2000 REPAIR!

83K MILES. ENG LIGHT AND TRAC LIGHTS COMES ON, WHILE DRIVING TRUCK GOES INTO LIMP MODE AND WILL NOT EXCELERATE PAST 2500 RPMS AND WILL NOT GO ANY FASTER THAN 35 MPH. ERROR CODE P2442 SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE PROBLEM. VERY DANGEROUS PROBLEM

WHILE DRIVING THE VEHICLE IN A SUBURBAN AREA IT LOST POWER, SLOWING TO 25 MPH MAXIMUM, I WAS ALMOST REAR ENDED. I SWERVED OFF THE ROAD INTO THE GRASS TO AVOID BEING HIT. THERE IS A PROBLEM WITH THE EMISSION SYSTEM. IT IS THE SECONDARY AIR INJECTION SYSTEM. TOYOTA HAS BEEN AWARE OF THIS PROBLEM FOR SOME TIME. SOME OF THE 2012 TOYOTA TACOMA'S HAVE A CUSTOMER SUPPORT / WARRANTY EXTENSION FOR THIS PROBLEM, NOT MINE.

WENT ON VACATION TO TEXAS, STOPPED TO GAS UP AND WHEN I WENT BACK ON INTERSTATE I HAD A DRAMATIC LOSS OF POWER. COULD NOT KEEP UP ENOUGH SPEED TO GO SPEED LIMIT. AIR CONDITIONER DID NOT WORK. AT DESTINATION A LOCAL TOLD ME ABOUT A REPAIR SHOP. COST ME A HUNDRED DOLLARS TO RESET TO FACTORY SPECS. THIS HAS HAPPENED AGAIN FOUR OTHER TIMES. I DISCONNECTED BATTERY AND RESET MYSELF. NOW IT`S A DAILY THING.

75K MILES. CEL LIGHT AND TRAC OFF LIGHTS COME ON, TRUCK GOES INTO LIMP MODE AND WILL NOT ACCELERATE PAST 2500 RPMS, AND WILL NOT REACH SPEEDS ABOVE 35 MPH. VERY VERY DANGEROUS AND ENDANGERS NOT ONLY THE TRUCKS DRIVERS, BUT OTHER DRIVERS ON THE ROAD. THIS IS DUE TO A FAULTY DIVERTER VALVE THAT IS A KNOWN ISSUE THAT TOYOTA HAS ISSUED RECALLS ON FOR OTHER MODELS WITH THE SAME PROBLEM.

AIR INJECTOR PUMP CAUSING ENGINE LIGHT AND TRAC LIGHT TO COME ON AND SUDDEN LOSS OF POWER. VEHICLE IN MOTION WHEN OCCURRING.

SECONDARY AIR INJECTOR SYSTEM SWITCHING VALVE PROBLEM AT 55000+ ODOMETER

SECONDARY AIR INJECTION PROBLEMS (VALVES AND/OR PUMP) CAUSES A CHECK ENGINE LIGHT TO COME ON, AND PUTS THE ENGINE IN "LIMP HOME" MODE, WITHOUT WARNING, WHICH LIMITS TOP SPEED TO ~40MPH. THIS IS NOT ONLY RIDICULOUS, BUT DANGEROUS, ESPECIALLY IF IT HAPPENS WHILE ON A FREEWAY. THE "LIMP HOME" MODE PERSISTS UNTIL THE CODE IS CLEARED, BY USING AN ODB TOOL, OR CLEARING THE ECU BY OTHER MEANS. THIS HAS HAPPENED TO ME 3 TIMES WHERE, WITH NO WARNING, THE TRUCK SUDDENLY LOST POWER, AND I HAD TO FIND THE NEAREST "SAFE SPOT" TO GET OUT OF TRAFFIC AND PULL OVER. TOYOTA HAS ACKNOWLEDGED THIS ISSUE IN A TSB, BUT PROVIDES NO RECALL, DESPITE THIS BEING A POTENTIALLY DANGEROUS SITUATION WHEN IT HAPPENS.

VEHICLE WAS IN MOTION AND CHECK ENGINE LIGHT CAME ON. CAR IMMEDITELY LOST POWER. COMPUTER CODES P2440 AND P2442 INDICATED ISSUES THAT WOULD NOT EFFECT NORMAL OPERATION OF THE VEHICLE- JUST EMMISION CONTROL ISSUES. 98,000 MI. ON VEHICLE WHEN IT OCCURRED. VEHICLE WOULD NOT GO OVER 40 MPH.

SECONDARY AIR PUMP AND SWITCHING VALVES FAILED ON THE HIGHWAY WITH ONLY 62,000 MILES. TRUCK FORCED INTO LIMP MODE AND I WAS NOT ABLE TO TRAVEL OVER 20MPH. THE TRUCK HAD A CHECK ENGINE LIGHT AND TRAC CONTROL LIGHT APPEAR. TOYOTA ATTEMPTED TO CHARGE ME OVER $2100 TO FIX. AFTER READING ABOUT THE ERROR CODES THIS IS A COMMON PROBLEM FOR ALL 2012 TACOMA OWNERS AND TOYOTA WARRANTY REFUSES TO COVER ANY OF THE COST OR RECALL THE PART (THE SAME ISSUE ON TOYOTA TUNDRAS WAS RECALLED).

DRIVING VEHICLE AND ALL OF A SUDDEN ENGINE LOOSES POWER. TRUCK DID NOT DIE AND WOULD SLOWLY ACCELERATE. I HAD TRAFFIC BEHIND ME HONKING AND CUTTING ME OFF UNTIL I COULD GET TO A PULL OFF SPOT. I HAD THE VEHICLE TOWED TO A MECHANIC AND DISCOVERED THE SECONDARY AIR PUMP AND VALVES WERE THE CAUSE CAUSING THE LOTS OF ACCELERATION. THIS IS A VERY DANGEROUS AND KNOWN ISSUE FOR TOYOTA OWNERS AFTER RESEARCHING. I DO HAVE REPAIR RECEIPT WHICH IS VERY COSTLY

AT 60,000 MILES CHECK ENGINE LIGHT AND TRAC OFF LIGHTS COME ON WHEN STARTING UP TRUCK IN MORNING. THIS PUT THE TRUCK INTO LIMP MODE. MY MECHANIC CLEARED THE CODES BUT DID NOT WANT TO GET INVOLVED IN REPAIRING AS HE COULDN'T GUARANTEE IT WOULDN'T HAPPEN AGAIN DOWN THE ROAD AND SAID TOYOTA WILL NOT WARRANTY THE REPLACEMENT PARTS. DEALER ADVISED APPROXIMATELY $2,000 TO REPAIR. AFTER SEEING ALL THE OTHER COMPLAINTS FROM 2012 TACOMA OWNERS, I CAN NOT BELIEVE TOYOTA WILL NOT COVER THIS UNDER A RECALL SINCE THEY COVERED THE EXACT SAME PROBLEM WITH THE TUNDRA AND SEQUOIA.

VACUMME SWITCHING VALVE AND AIR INJECTION PUMP FAILURE AT 43,000 MILES, COST TO REPAIR IS $2052.32. THIS PART IS PART OF THE EMISSION CONTROL SYSTEM AND SHOULD BE COVERED BY TOYOTA BUT IS NOT. WHEN THIS VALVE THROWS A CHECK ENGINE LIGHT THE TRUCK GOES INTO LIMP MODE AND IS VERY DANGEROUS TO DRIVE AS IT HAS REDUCED POWER.

39K MILES THROWS CODES RELATING TO SECONDARY AIR INJECTION PUMP. $2100 QUOTE TO FIX. MANY OTHER OWNERS WITH THE SAME PROBLEM

CHECK ENGINE LIGHT AND TRAC OFF LIGHT CAME ON AND NEXT THING THE CAR WOULD NOT ACCELERATE PROPERLY WHILE PULLING OUT ON TO A HIGHWAY HEADING UP HILL I HAD NO POWER. FORTUNATELY I WAS NOT KILLED BY THE 50 PLUS MILE PER HOUR TRAFFIC. AFTER MAKING DOWN THE HIGHWAY WAS ABLE TO GET INTO A PEP BOYS WHERE THEY CODED THE SECONDARY AIR SYSTEM. THIS IS A SERIOUS ISSUE THAT COULD HAVE KILLED ME OR SOMEONE ELSE. I PLAN TO CONTACT AN ATTORNEY AFTER FINDING OUT THEY ONLY COVER THEIR MOST EXPENSIVE VEHICLES WITH THEY EXACT SAME SYSTEM. I GUESS 35K ON A TRUCK WASN'T ENOUGH. THE PART COST ME $770 DOLLARS AND I'M NOT SURE IF ITS SAFE BECAUSE I HAD TO DO JOB MYSELF BECAUSE I COULD NOT AFFORD $2000.00 FOR 2 HOURS WORK.

OEM PARTS FAILURE DUE TO MANUFACTURERS DEFECT. THIS EXACT ISSUE PROMPTED RECALL OF THE TOYOTA TUNDRA. DEALERSHIP REPORTS NUMEROUS CUSTOMERS WITH SAME ISSUE. REPAIR IS OVER $2,000. THIS IS SERIOUS ISSUE. AIR INJECTION PUMPS AND SWITCHING VALVES ARE FAULTY ALLOWING WATER INTO THE SYSTEM AND CAUSING THE ENGINE TO SEIZE UP AND DECREASE ENGINE SPEED. THIS HAPPENED ON I-90 IN HEAVY TRAFFIC CAUSING OTHER MOTORISTS TO APPLY BREAKS QUICKLY. CONTACTED TOYOTA AND THEY ARE AWARE OF THE ISSUE BUT HAVE NO PLANS TO INITIATE A RECALL.

RECENTLY I WAS DRIVING MY 2012 TOYOTA TACOMA ON THE HIGHWAY AT A SUSTAINED SPEED OF 70 MPH. A CHECK ENGINE LIGHT CAME ON AND MY CAR INSTANTLY DROPPED IN SPEED TO LESS THAN 40 MPH WHILE IN FAST MOVING TRAFFIC. I WAS ALMOST REAR ENDED BY A LARGE TRUCK AND WAS FORCED TO CROSS MULTIPLE LANES OF TRAFFIC TO GET TO THE BERM AND ASCERTAIN THE SITUATION. AS I COULD FIND NO ISSUES UPON INSPECTION, I PRECARIOUSLY DROVE THE VEHICLE TO A SERVICE STORE TO READ THE ERROR CODES. THE VEHICLE SHOWED P2440 P2442 ERROR CODES INDICATING SECONDARY AIR INJECTION FAILURES. APPARENTLY, THE VEHICLE WENT INTO LIMP MODE UPON THROWING THESE CODES WHICH LIMITS SPEED AND ENGINE RPM. THIS ALMOST CAUSED A HUGE ACCIDENT AND PUT ME INTO A A VERY DANGEROUS SITUATION. ADDITIONALLY UPON RESEARCHING THESE ISSUES, IT SEEMS THIS IS A WELL DOCUMENTED ISSUE CAUSED BY MANUFACTURING DEFECTS ISOLATED TO THE 2012 MODEL YEAR. APPARENTLY, THE SYSTEM IS DEFECTIVE IN MULTIPLE WAYS. FIRST, A PIECE OF FOAM IS INSIDE THE SECONDARY AIR PUMP WHICH DEGRADES AND IS SUCKED INTO THE FAN WHICH NOT ONLY CAUSES STOPPAGE AND BURNING OUT THE FAN MOTOR BUT ALSO ALLOWS FOR STINKY RESIDUE AND DEBRIS TO ENTER THE VALVES CAUSING THEM TO JAM OPEN OR CLOSED. ADDITIONALLY, THE SYSTEM ALLOWS MOISTURE TO BE SUCKED INTO THE VALVES ADDING TO CORROSION AND DEGRADATION OF THE VALVES LEADING TO THEM TO BE STUCK. THIS IS A ROUGHLY 1500.00-2000.00 REPAIR. IT IS A QUITE FREQUENT PROBLEM WITH THIS MODEL YET IS NOT COVERED UNDER RECALL OR SERVICE BULLETIN. TOYOTA HAS ACKNOWLEDGED THE ISSUE YET NOT TAKEN ANY ACTION. ADDITIONALLY, THEY HAVE HAD SIMILAR PROBLEMS WITH THE TUNDRA/SEQUOIA AND OFFERED REMEDY TO OWNERS VIA EXTENDED WARRANTY. THIS IS NOT ONLY A QUALITY CONTROL ISSUE BUT MORE IMPORTANTLY A SEVERE SAFETY ISSUE WITH THE AUTOMATIC REDUCTION TO A SLOW SPEED IN FAST HEAVY TRAFFIC.

MY 2012 TACOMA IS THROWING LIGHTS ON FOR A NEW SECONDARY AIR INJECTOR VALVE , PARTS P2440 AND P2442. THE TOYOTA MECHANIC SAID THIS IS A COMMON PROBLEM WITH THESE OVER THE PAST FEW YEARS AS THE 2012'S HOLD MOISTURE AFTER SHUT DOWN AND THE VALVES BREAK DOWN. I SEE THIS IS A COMMON PROBLEM ONLINE AND A VERY EXPENSIVE FIX FOR US ALL. THIS SHOULD BE COVERED FIX, JUST BECAUSE IT DOESN'T CAUSE IN IMMINENT HEALTH HAZARD DOESN'T MEAN IT'S NOT A PROBLEM THAT TOYOTA SHOULD COVER. THE ISSUE WITH THE VEHICLE ONCE A SENSOR DETECTS THIS PROBLEM IS THAT IT PUTS IT IN A LIMP MODE, AND MAKES THE VEHICLE VERY SLUGGISH EVEN DIFFICULT TO ACHIEVE 45 MPH.

ERROR CODE P2442 SECONDARY AIR INJECTION VALVE STUCK OPEN. TRUCK IMMEDIATELY GOES INTO "LIMP' MODE AND WILL NOT ACCELERATE OVER 20MPH. EXTREMELY UNSAFE TO HAVE THE VEHICLE DECELERATE ON A HIGHWAY FOR A KNOWN ISSUE THAT HAS PROMPTED WARRANTY EXTENSIONS ON TOYOTA TUNDRA'S.

FAULT CODES P2440 AND P2442, POWERTRAIN - AUXILIARY EMISSION CONTROLS. AIR PUMP FAILING AT 41,000 MILES. DEALER REPAIR COST IS $1,900. VEHICLE GOES IN TO "LIMP MODE" WHEN STARTED, THAT DRASTICALLY REDUCES POWER.

SECONDARY AIR INJECTION SWITCHING VALVE MALFUNCTION RELATED TO EMISSIONS. CODE P2440 & P2442,

TL* THE CONTACT OWNS A 2012 TOYOTA TACOMA. AFTER STARTING THE VEHICLE, THE CHECK ENGINE, TRACTION CONTROL, AND MAINTINENCE INDICATORS REMAINED ILLUMINATED. WHILE DRIVING, THE VEHICLE WOULD NOT ACCELERATE PAST 25 MPH. THE VEHICLE WAS TAKEN TO AUTONATION TOYOTA IN HOUSTON, TEXAS WHERE IT WAS DIAGNOSED THAT THE ENGINE AIR PUMP AND AIR VALVE WERE FAULTY AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 45,000.

TL* THE CONTACT OWNS A 2012 TOYOTA TACOMA. WHILE DRIVING 62 MPH, THE CHECK ENGINE INDICATOR ILLUMINATED AND THE VEHICLE BEGAN TO LOSE POWER. THE CONTACT STATED THAT THE VEHICLE EXPERIENCED A LIMP HOME SETTING. THE CONTACT STATED THAT HE WAS AES CERTIFIED. THE CONTACT STATED THAT THE TOW HITCH WAS IN USE WHEN THE FAILURE OCCURRED. THE VEHICLE WAS TAKEN TO A LOCAL DEALER (FIORE TOYOTA VOLKSWAGEN 1000 S. LOGAN BLVD, HOLIDAYSBURG, PA 16648) WHERE IT WAS DIAGNOSED THAT THE SECONDARY AIR INJECTION SWITCHING VALVE FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED BY THE CONTACT. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE, BUT DID NOT OFFER ANY ASSISTANCE. THE FAILURE MILEAGE WAS APPROXIMATELY 88,000.

I WAS LEAVING WORK AND PULLING ONTO THE HIGHWAY WHEN I NOTICED MY CHECK ENGINE LIGHT CAME ON, AS WELL AS THE TRAC OFF LIGHT. I WENT TO PULL INTO TRAFFIC AND IMMEDIATELY REALIZED THAT WHATEVER WAS WRONG PUT MY TRUCK INTO LIMP MODE AND HAD A 2500 RPM LIMIT. THIS WAS A 60 MPH HIGHWAY AND I COULDN'T GO MORE THAN 35 MPH. THE TRAFFIC COMING WAS IMMEDIATELY UPON ME AND I HAD TO PULL OVER AND PUT ON MY HAZARD LIGHTS AS THESE VEHICLES HAD TO SLAM ON THEIR BRAKES, HONK, AND SWERVE AROUND ME. I BROUGHT IT INTO THE DEALERSHIP AND THEY READ CODE P2442. WHICH IS FOR A STUCK SECONDARY AIR INJECTION VALVE. THEY FOUND WATER IN THE VALVES AND THEY HAD TO BE REPLACED. DOING SOME RESEARCH I FOUND THIS IS A VERY COMMON ISSUE IN 2ND GEN TACOMAS, MOSTLY THE 2012. THIS A VERY WELL KNOWN ISSUE, ESPECIALLY TO TOYOTA, AND THEY HAVE SO FAR DONE NOTHING ABOUT IT. THIS LED TO A VERY DANGEROUS NEAR CRASH INCIDENT WHICH I THEN HAD TO PAY OVER 1200 DOLLARS TO FIX. THIS IS COMPLETELY UNACCEPTABLE. TOYOTA MUST AT LEAST TAKE OWNERSHIP OF THEIR POORLY DESIGNED PARTS AND COVER THE REPLACEMENT OF THESE VALVES AND PUMPS. THIS IS HAPPENING ALL OVER THE COUNTRY ON A CONSISTENT AND PERSISTENT BASIS. PLEASE MAKE TOYOTA ADDRESS THIS, THEIR CUSTOMERS DESERVE SO MUCH BETTER.

SECONDARY AIR INJECTION SYSTEM (P2442). THIS HARDWARE DEFECT HAS BEEN A RECALL FOR TUNDRA BUT NOT FOR TACOMA. THE PART IS DEFECTIVE ON MOST 2012 TACOMA AND VERY EXPENSIVE TO REPLACE. THERE ARE SAFETY ISSUE AS THE VEHICLE UNABLE TO ACCELERATE, BUT ONLY ABLE TO LIMP. THERE ARE MANY DISCUSSIONS ABOUT THIS ISSUE BUT TOYOTA HAS NOT DONE ANYTHING ABOUT THIS.

FAILURE OF THE SECONDARY AIR INJECTION PUMP AND VALVE EMISSION SYSTEM PROMPTED ENGINE TO RUN IN A REDUCED POWER MODE, AND THIS OCCURRED ON A ON A RELATIVELY NEW VEHICLE WITH BELOW AVERAGE MILEAGE. WHILE SETTING MAY PROTECT ENGINE, THIS CREATED AN UNSAFE DRIVING ENVIRONMENT FOR VEHICLE WITHIN FAST MOVING TRAFFIC. MY COMPLIANT IS NOT RELATED TO THE REDUCED DRIVING MODE THAT MAY HAVE PROTECTED THE ENGINE, BUT RATHER THE POOR DESIGN OF THE AIR-PUMP/VALVE SYSTEM THAT PREMATURELY FAILED CAUSING THE REDUCED POWER MODE.

MY TRUCK'S CHECK ENGINE LIGHT AND TRAC OFF LIGHT CAME ON AND I TOOK IT TO MY LOCAL REPAIR SHOP. THE MANAGER TOLD ME THAT AFTER THE LEVEL 1 DIAGNOSTIC, A P2442 ERROR CODE APPEARED (SWITCHING VALVE STUCK). THE VALVES, AND AIR PUMP ARE PART OF THE SECONDARY AIR INJECTION SYSTEM WHICH DIVERTS SOME EXHAUST BACK INTO THE ENGINE TO REDUCE EMISSIONS OUTPUT. AS PART OF THE TRUCK'S EMERGENCY SYSTEM, THE TRUCK LIMITED THE ENGINE OPERATION PARAMETERS TO ABOUT 2000RPM, AND ABOUT 40MPH MAXIMUM. EXPRESS OIL CHANGE AND TIRE ENGINEERS QUOTED THE PARTS AT AROUND $1500, NOT INCLUDING LABOR. THE DAY OF DIAGNOSIS, THE TRUCK HAD 72,952 MILES AND WAS PURCHASED NOV. 2011. CURRENTLY UNABLE TO SAFELY DRIVE MY TRUCK IN NORMAL TRAFFIC. FACING A NEARLY $2K BILL, I DECIDED TO DO SOME DIGGING INTO EMISSIONS WARRANTY INFORMATION AND FOUND THAT THOSE PARTS WERE NOT GOING TO BE COVERED BY THE 8YR/80,000 MILE FEDERAL EMISSION CONTROL WARRANTY AS OUTLINED IN MY WARRANTY AND MAINTENANCE GUIDE, EVEN THOUGH THESE ARE A CRITICAL PART OF THE SYSTEM. WHILE ONLINE, I READ SEVERAL POSTS ON TACOMAWORLD.COM WHERE SEVERAL OTHERS WERE HAVING THE SAME ISSUES. WHAT WAS MORE CONCERNING WAS THAT THIS VERY SAME ISSUE WAS VERY COMMON IN TOYOTA TUNDRA NOT LONG AGO AND THE MANUFACTURER EXTENDED THEIR WARRANTIES TO COVER THE COSTS BECAUSE IT WOULD APPEAR TO BE A MANUFACTURER DEFECT. NOW, THE VERY SAME THING IS HAPPENING WITH TACOMA BUT THE EXTENDED WARRANTY HAS NOT BEEN EXTENDED TO MY TRUCK. THE SERVICE LIGHTS HAVE SINCE COME BACK ON AND THE TRUCK IS NOT DRIVABLE, I HAVE YET TO GET A HOLD OF TOYOTA BUT BECAUSE OF THE HOLIDAY, I WILL HAVE TO WAIT UNTIL THE MORNING BUT NOT EXPECTING MUCH. WHO WILL PAY FOR MY RENTAL CAR WHILE I'M PAYING THIS BILL? HTTPS://WWW.TACOMAWORLD.COM/THREADS/SECONDARY-AIR-INJECTION-SYSTEM-P2440-AND-P2442.370792/ HTTP://WWW.TUNDRAHEADQUARTERS.COM/BLOG/TOYOTA-WARRANTIES-AIR-INJECTION-PUMP/

AS I WENT FROM SIDE ROAD TO MAIN ROAD, TRUCK WOULD NOT ACCELERATE TO FULL SPEED EVEN WITH FOOT ON THE PEDAL, INDICATORS TRAC OFF AND CHECK ENGINE WERE LIT. WENT TO MECHANIC AND ERROR CODES P2440 AND P2442 INDICATED MALFUNCTION IN SECONDARY AIR INJECTION SYSTEM. WAS TOLD NEW AIR PUMP AND DIVERTER VALVE REQUIRED AT COST OF $2K. TRUCK HAS LESS THAN 30K ON IT,BUT IS 5 YEARS OLD. GOING INTO LIMP MODE IS DANGEROUS AS THE MAIN STREET IS 55MPH. TOYOTA STATES TUNDRAS HAVE SAME ISSUE THAT IS NOW COVERED BY 10 YEAR/150K WARRANTY, BUT NOTHING FOR TACOMA OWNERS. SO I AM QUITE ANGRY WITH THAT AS WELL. HAVE READ ONLINE THAT MANY OTHER OWNERS ARE HAVING SAME ISSUES. TOYOTA SHOULD RECALL THESE DEFECTIVE PUMPS AND VALVES IN ADDITION TO DISABLING THE LIMP MODE AS IT IS VERY DANGEROUS.

SECONDARY AIR INJECTION VALVE QUIT WORKING AND PUT MY TRUCK INTO A 'LIMP MODE.' DURING THIS TIME MY SPEED WAS CUT NO MORE THAN 40 M.P.H. I WAS MERGING ONTO THE HIGHWAY AT THE TIME AND IT CREATED A VERY UNSAFE CONDITION. I STARTED RESEARCHING THE ISSUE AND SAW A TON OF OTHER PEOPLE HAD THE EXACT SAME ISSUE. I'M SURE TOYOTA KNEW ABOUT IT AS WELL, BECAUSE THE MECHANIC AT THE DEALERSHIP DID. WHY DIDN'T THEY PUT OUT AN ALERT OR RECALL??

2012 TOYOTA TACOMA. THE VEHICLE HAS CODES P2440, P2441, P2442 RELATING TO THE SECONDARY AIR INJECTION SYSTEM (SAIS) VALVES BEING STUCK OPEN/CLOSED. THIS APPEARS TO BE A COMMON PROBLEM WITH 2012 TACOMA VEHICLES AND SEVERAL YEARS FOR TUNDRA VEHICLES. FOR THE TUNDRA, TOYOTA INSTITUTED A CUSTOMER SUPPORT PROGRAM AND EXTENDED THE WARRANTY COVERAGE FOR THE SAIS. WITH THE VEHICLE HAVING ONLY 47,391 MILES, IT IS OUTRAGEOUS THAT THE SAIS WOULD HAVE ISSUES OR FAILURES ESPECIALLY BEING A TOYOTA. SINCE THE TRUCK IS IN LIMP MODE AND NOT SAFE TO DRIVE, IT WILL HAVE TO BE TOWED TO A DEALERSHIP. BETWEEN THIS ISSUE AND A NOISE AND PULLING PERIODICALLY FROM THE FRONT DIFFERENTIAL/DRIVETRAIN, WE ARE VERY DISAPPOINTED IN THIS VEHICLE.

MY 2012 TOYOTA TACOMA FIRST STARTED THROWING A P2442 ERROR CODE AND I HAD A MECHANIC CLEAR IT TWICE. NOW IT IS THROWING A P2440 AND P2442 ERROR CODE. THIS IS THE SECONDARY AIR INJECTION SYSTEM VALVE ASSEMBLY. BOTH BANK 1 AND BANK 2 VALVES ARE STUCK OPEN. I CALLED TOYOTA CORPORATE (1-800-331-4331) AND FILED A COMPLAINT AFTER SEEING ALL OF THE OTHER 2012'S WITH THE SAME PROBLEM. THEY JUST WANT ME TO GET IT TO A TOYOTA DEALERSHIP TO READ THE CODE AND THEN GO FROM THERE. UNFORTUNATELY I DON'T LIVE NEAR A DEALERSHIP AND THEY WANT TO CHARGE ME FOR A DIAGNOSTIC TEST THAT MY LOCAL MECHANIC JUST PERFORMED. THE TRUCK IS IN LIMP MODE WITH THE CHECK ENGINE AND TRAC OFF LIGHTS ILLUMINATED.

2012 TACOMA WITH 24K MILES. CHECK ENGINE LIGHT AND TRC LIGHT CAME ON WITH TRUCK IN LIMP MODE WHEN I STARTED IT TO GO TO WORK. CODES P0412 P2433 P2438 P2442. TOYOTA WONT COVER THIS AND ITS A DEFECT IN MANY MANY 2012 TACOMAS.

CEL AND TRAC OFF LIGHTS CAME ON AND TRUCK WENT INTO LIMP MODE. I WAS ONLY ABLE TO DRIVE 25-35MPH IN LIMP MODE. TOOK 2012 TOYOTA TACOMA TO LOCAL MECHANIC AND THE TROUBLE CODE WAS P2442, SECONDARY AIR INJECTION SYSTEM BANK 2 VALVE STUCK OPEN. CONTACTED TOYOTA DEALER BUT NO HELP EVEN THOUGH TOYOTA CORPORATE IS AWARE OF THE PROBLEM ON 2012 TOYOTA TACOMAS AS WELL AS OTHER MODELS.

EMISSIONS AIR PUMP VALVE WENT OUT WITH 60,200 MILES ON THE TRUCK. THE TRUCK IS BONE STOCK AND HAS BEEN VERY WELL MAINTAINED. AFTER RESEARCH ITS SEEMS THAT NUMEROUS PEOPLE ARE HAVING ISSUES WITH THIS SAME EXACT PART ON THE 2012 TACOMAS. TOYOTA EXTENDED A RECALL ON THE TUNDRA'S BECAUSE OF THIS PART, BUT NOT THE TACOMAS. THE TRUCK IS CURRENTLY IN LIMP MODE AND WILL NOT GO PAST 40MPH, AND THE DEALER WANTS $1,075 TO FIX IT. THIS OCCURRED ON MY WAY TO WORK THIS MORNING WHILE GETTING ON THE FREEWAY, AND WAS QUITE SCARY TO NOT BE ABLE TO GO OVER 40MPH ON A BAY AREA FREEWAY WITH CARS HONKING AND FLYING PAST ME.

BOUGHT TRUCK NEW IN 2012 AND MAINTAINED 100% RECOMMENDED MAINTENANCE AT DEALER. AT 64,500 MILEAGE, CHECK ENGINE LIGHT CAME ON WHILE DRIVING, AND WE DROVE TRUCK STRAIGHT TO DEALER SERVICE GARAGE. DEALER DETERMINED SECONDARY AIR INJECTION PUMP HAD CONTAMINATED WITH WATER, RESULTING IN RUST IN SYSTEM (VALVES ALSO). REPLACED PUMP AND VALVE ASSEMBLY AND GASKET. SERVICE ADVISOR SAID THE SAME PARTS WERE USED AND RECALLED IN RESPONSE TO REPORTS OF AIR INDUCTION PUMP ASSEMBLIES AND/OR AIR INJECTION SWITCHING VALVES ISSUES ON THEIR 2007-2010 TUNDRA AND 2008-2010 SEQUOIA MODELS, TOYOTA HAS DECIDED TO INCREASE ITS WARRANTY ON THESE PARTS AND IS EVEN OFFERING A REIMBURSEMENT IF YOU ALREADY HAD THIS ISSUE FIXED. TACOMA'S NEED TO BE INCLUDED IN THE RECALL REIMBURSEMENT! WHEN WE ASKED ABOUT HOW TO PREVENT FUTURE ISSUES, SERVICE TECH INFORMED US THE PART HAS BEEN "RE-DESIGNED" TO PREVENT THE PROBLEM FROM RE-OCCURRING. TOTAL BILL FROM DEALER WAS $1968.29. THIS VEHICLE HAS NEVER BEEN OFF ROAD, NEVER BEEN IN FLOOD CONDITIONS, AND IS A COMMUTER VEHICLE ON PAVED ROADS.

SECONDARY AIR INJECTION VALVE STUCK OPEN CAUSING TRUCK TO ENTER "LIMP-MODE" WHILE COMMUTING ON CONGESTED FREEWAY SYSTEM. THIS PRESENTED A SAFETY HAZARD TO MYSELF AND MY FAMILY TRYING TO MERGE OFF THE FREEWAY THROUGH TRAFFIC WITHOUT ANY POWER.

4.0L V6, DCSB, AT, OR PACKAGE, 4X4, 41.5K MILES, CEL ON, TCL ON, LIMP MODE ON, CODES P2440 P2442. REFERENCES A SECONDARY AIR PUMP VALVE ISSUE. TRUCK WAS STARTED IN THE MORNING, REVERSED OUT OF DRIVEWAY, CEL, TCL, AND LIMP MODE ACTIVATED WHEN PUT INTO DRIVE. UNABLE TO REACH SAFE OPERATING SPEEDS DUE TO LIMP MODE. VEH WAS ON CITY STREET WHEN CODES TRIGGERED LIMP MODE. FAILURE OF POORLY DESIGNED VALVES AND SYSTEM CAUSES VALVES TO REMAIN STUCK OPEN ALLOWING A LARGER THAN NORMAL VOLUME OF EXHAUST FUMES TO RECIRCULATE TO THE INTAKE THROUGH ALL OPERATING RANGES INSTEAD OF JUST ENGINE START UP. POTENTIAL FOR ENGINE FAILURE AND FIRE.

AS I READ THROUGH THE COMPLAINTS ON HERE, IT SEEMS MOST ARE FOR THE SAME ISSUE I HAVE SEEN. AS IT IS THE BIGGEST COMPLAINT ITEM FOR 2012 TACOMA ON THIS WEBSITE, AND THE FACT THAT THERE IS A RECALL ON TUNDRA FOR THE SAME ITEM, AND THAT 2013 TACOMA WERE REDESIGNED TO FIX, THIS IS CLEARLY A KNOWN ISSUE OF A FAULTY PART/DESIGN OF THE THE AIR INJECTION PUMP VALVE. IT IS UNACCEPTABLE THAT NOTHING IS DONE ABOUT THIS AND THE DANGER IT POSES. LIKE THE OTHERS, I GOT A CHECK ENGINE LIGHT/TRAC OFF ONE EVENING WHEN I STARTED MY TRUCK. MY TRUCK STARTED UP FINE, AND I DIDN'T NOTICE A PROBLEM UNTIL I TRIED TO MERGE ONTO A 60 MPH ROAD. I TRIED TO ACCELERATE AND MERGE BUT I ALMOST CAUSED A PILE UP AS I COULD NOT ACCELERATE BEYOND 35 MPH. LUCKILY, ALL I GOT WAS A BUNCH OF HONKING. THIS IS A VERY DANGEROUS SITUATION! AFTER FURTHER RESEARCH, I SAW THE CODES P2440 AND P2442 AND UNDERSTAND IT IS A LIMP MODE DUE TO AN EMMISIONS ITEM AT STARTUP. BEFORE BEING ABLE TO FIX, I HAD TO WORK A SHIFT AT MY SECOND JOB OF SKI PATROL IN THE ROCKY MOUNTAINS. AS MY TRUCK OBVIOUSLY COULDN'T MAKE IT UP THE CANYON, I WAS FORCED TO BORROW ANOTHER CAR, AND ALL I COULD GET WAS A 2 WHEEL DRIVE. THERE WAS A LATE SEASON STORM, AND BECAUSE I DIDN'T HAVE MY 4X4 TRUCK I GOT STUCK OVERNIGHT IN THE MOUNTAINS. I SURVIVED, BUT TWICE BECAUSE OF THIS ISSUE I WAS FACED INTO A DANGEROUS SITUATION. I BOUGHT A NEW 4X4 FOR THE VERY REASON TO AVOID DANGERS LIKE THESE. GRANTED I HAVE 65K MILES NOW, BUT I DON'T EXPECT A VEHICLE TO HAVE MAJOR PROBLEMS LIKE THIS. IT IS EVEN WORSE TO FIND OUT THAT IT IS A KNOWN ISSUE AND NO ONE IS DOING ANYTHING ABOUT IT. IT IS A DISAPPOINTMENT THAT WITH A KNOWN ISSUE TOYOTA HAS NOT DONE SOMETHING ABOUT THIS FOR THE TACOMAS, BUT I AM EQUALLY SURPRISED THAT THERE ARE SO MANY COMPLAINTS AND EXAMPLES OF DANGEROUS SITUATIONS AND THE NHTSA HASN'T DONE ANYTHING EITHER.

SECONDARY AIR PUMP AND VALVE FAILURE. SECOND TIME IN 1 YEAR.

WHILE DRIVING ON A CITY STREET THE CHECK ENGINE LIGHT AND TRAC OFF LIGHT ILLUMINATED AND TRUCK WOULD NOT GO OVER 25 MPH. BROUGHT DIRECTLY TO MECHANIC THAT FOUND DIAGNOSTIC TROUBLE CODE P2442 - SECONDARY AIR INJECTION SYSTEM MALFUNCTION. AT 61K MILES THIS FAULTY PART WAS NOT COVERED UNDER ANY WARRANTY. THE PART COST ALONE WAS $1321 AND THEN ADD TAX AND LABOR FOR A TOTAL OF $1709! SO DISGUSTED WITH TOYOTA FOR NOT TAKING ACCOUNTABILITY FOR THIS FAULTY PRODUCT.

ECL CODE P2442, SECONDARY AIR HANDLER, EPA PART BUT TOYOTA DEALERS WON'T COVER UNDER EPA WARRANTY.

AIR VALVES IN EMISSION SYSTEM WENT BAD, WAS REDUCED TO DRIVING 35MPH IN HEAVY TRAFFIC, VERY UNSAFE. WAS QUOTED $2500 IN REPAIRS FOR REPAIRS RESULTING FROM FAULTY DESIGN. REPORTS RAMPANT ON THE INTERNET OF THIS PART FAILING. TPYOTA FIXED THE ISSUE ON LATER MODEL TACOMAS AND RECALLED TUNDRAS WITH THE SAME ISSUE BUT HAVE IGNORED THIS MAKE/MODEL/YEAR.

ON THE WAY HOME FROM A RECENT CAMPING TRIP MY CHECK ENGINE LIGHT AND TRAC LIGHT CAME ON IN MY TRUCK. THE TRUCK WENT INTO "LIMP" MODE WOULD NOT ACCELERATE UP A HILL ABOVE 20 MILES PER HOUR. WE DROVE TO THE NEAREST AUTO ZONE, THEY PULLED THE CODES P2436 AND P2442. I WAS ABLE TO CLEAR THE CODES AND MAKE IT HOME. I STARTED RESEARCHING THIS AND FOUND THE SECONDARY AIR SWITCHING VALVES TO BE A COMMON FAILURE ON TACOMAS AND TUNDRAS. I FEEL THIS PART NEEDS TO BE RECALLED AND UPGRADED, THIS COULD BE A MAJOR SAFETY ISSUE IF THE VEHICLE WENT INTO "LIMP" MODE IN HEAVY TRAFFIC OR WHILE CROSSING ACROSS HEAVY TRAFFIC. THE REPLACEMENT PART 25710-31022 WAS ORDERED FROM THE DEALERSHIP TODAY. I ALSO FILED A COMPLAINT WITH TOYOTA CUSTOMER SERVICE.

DRIVING HOME FROM WORK ON THE FREEWAY WHEN THE CHECK ENGINE LIGHT CAME ON, THEN THE ENGINE STARTED TO SLOW DOWN AND WOULD NOT GO ABOVE 35 MILES/HOUR ON THE FREEWAY. TOOK TO DEALER AND WAS TOLD SECONDARY AIR INJECTION SWITCHING VALVE STUCK OPEN (BANK 1 & 2) REQUIRING REPLACEMENT.

I HAVE A 2012 TOYOTA TACOMA 4X4 SPORT DOUBLE CAB LONGBED WITH 28860 MILES. I STARTED THE ENGINE AND NOTICED THE "CHECK ENGINE" AND "TRAC CONTROL" LIGHTS ON IN THE CLUSTER. AS I WAS DRIVING I NOTICED A LACK OF POWER IT WAS IN "LIMPED MODE". MADE IT TO MY MECHANIC WHO DID A CODE CHECK WITH READER, CODES P2440 AND P2442 SHOWN WHICH IS SECONDARY INJECTION PUMP VALVE MALFUNCTION. THE CONCERNING ASPECT IS THAT WITH SUCH LOW MILAGE THIS MALFUNCTION OCCURS THAT MAKES THE TRUCK GO INTO LIMP MODE WHICH CAN BE DANGEROUS IN ANY GIVE SITUATION ON THE HIGHWAYS. TOYOTA MUST REALLY CONSIDER INVESTIGATING THIS DEFECT.

PULLED ONTO THE INTERSTATE AND THE TRUCK WOULD NO ACCELERATE. PUT ON MY HAZARDS AND TRIED TO AVOID GETTING HIT. GOT OFF ON THE NEXT EXIT. HAD TO GO UP A HILL TO GET HOME AND TRUCK WAS STRUGGLING TO MAINTAIN 20 MPH. TOOK IT TO THE DEALER WHO SAID IT WAS THE AIR INJECTION VALVES AND THAT THE TRUCK HAD GONE INTO LIMP MODE BECAUSE OF THE EMISSIONS PROBLEM. CODES WERE P2440, 2442. DEALER SAID PROBLEM IS NOT COVERED BY POWERTRAIN WARRANTY AND EMISSIONS WARRANTY EXPIRED.

WHILE DRIVING AND TURNING ONTO A HIGHWAY, "CHECK ENGINE"AND "TRAC OFF" WARNING LIGHTS CAME ON AS I PULLED INTO TRAFFIC. TRUCK WENT INTO LIMP MODE SO I COULDN'T ACCELERATE. ONCOMING TRAFFIC WORKED AROUND ME AS I TURNED ON MY HAZARD LIGHTS. SECONDARY AIR INJECTION SYSTEM P2440 AND P2442 ARE THE ERROR CODES ASSOCIATED WITH THE VALVES STUCK OPEN.

2012 WITH ONLY 24,900 MILES AND MY VEHICLE HAS THE SAME ISSUE AS THE TOYOTA TUNDRA ISSUE RELATING TO SECONDARY AIR INJECTION PUMP. DEALER SAYS IT'S NOT COVERED. THE ARE AN AWFUL LOT OF PEOPLE WITH THE SAME PROBLEM ON THEIR TACOMA'S. IT'S NO FAIR!

CODE P2442: SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE STUCK OPEN BANK 2. THIS HAPPENED ON A VEHICLE THAT DOES NOT TOW, DRIVE OFF ROAD, AND IS IN WARM WEATHER CLIMATE, AUSTIN, TX. MY COMMUTE TO WORK IS 5 MILES, EACH WAY. TOYOTA SAYS THIS IS NOT COVERED UNDER POWER TRAIN OR EMISSIONS WARRANTY. THIS IS A $2,000 FIX FOR A VEHICLE WITH ONLY 59,000 MILES.

SECONDARY AIR INJECTION SYSTEM FAILURE. IF YOU LOOK IN LINE IT IS AN EPIDEMIC WITH 2012 AROUND 50,000 MILES. 2000 $ REPAIR. THEY DON'T COVER. LOST POWER AT 75 ON THE HIGHWAY AND ALMOST GOT KILLED.

CHECK ENGINE CODE- P2442. THIS HAS BEEN A COMMON ISSUE WITH TOYOTA SUVS, AND TRUCKS!

THE ENGINE CHECK AND TRAC OFF LIGHTS ON WHEN I DRIVE ON HIGHWAY. THE SECONDARY AIR INJECTION SYSTEM FAILURE THE DEALER CHECKED, IT WILL COST $2000 TO FIX IT, IT IS ONLY 69K MILES AND 5 YEARS OLD VEHICLE. I COULD NOT ACCELERATE THE VEHICLE ON HIGHWAY AND IT SUDDENLY SLOW DOWN.

TRUCK NORMALLY STARTS RIGHT UP, CRANKED IT OVER NO START. TRIED IT AGAIN AND IT STARTED, BUT THE "CHECK ENGINE" AND THE "TRAC CONTROL" LIGHTS STAYED ON. TRIED GETTING ON THE FREEWAY AND HAD VERY LITTLE POWER GETTING ON THE ON-RAMP. PUT THE FLASHERS ON TO PREVENT CARS EXITING THE FREEWAY @ 65 MPH FROM CRASHING INTO ME AND MY LIMPING TACOMA. THEY ALSO PUT THEIR FLASHERS ON TOO. VERY UNSAFE! LIMPED TOWARDS HOME ON SURFACE STREETS....1 HOUR DRIVE TOOK ME 2. SCANNED THE ERROR CODES AND P2440 AND P2442 CAME UP, SWITCHES STUCK OPEN IN THE #1 & #2 BANK. AFTER SPENDING $1470.54 FOR PARTS I MADE THE REPAIRS. LOOKED @ A CO-WORKERS 2008 TACOMA AND THIS BAD IDEA IS NOT ON HIS TACOMA.....HHHHHMMMM. HE,S JUST LUCKY I GUESS. PLEASE HELP.VERY UNSAFE DESIGN, VERY EXPENSIVE REMEDY

REPLACEMENT AIR INJECTION VALVES AND PUMPS FOR SECONDARY EMISSIONS CONTROL SYSTEM. TOYOTA WANTS 2200 FOR AN ISSUE THEY ARE AWARE OF AND HAVE ALREADY RELEASED SERVICE BULLETINS FOR ON THE TUNDRA AND SEQUOIAS. ENGINE CODES P2442 AND P2446. WHEN THE CODES ARE THROWN THE CAR IS PUT INTO LIMP MODE AND DECELERATES TO 35 MPH, EVEN THOUGH THIS IS A NON-ESSENTIAL EMISSIONS SYSTEM.

SECONDARY AIR INJECTION SYSTEM FAILURE. FAILURE CODES OF P2440 AND 2442 OCCURRED DURING HIGHWAY DRIVING, CAUSING VEHICLE TO GO INTO LIMP MODE. THE VEHICLE AT THIS POINT WAS UNSAFE TO DRIVE DUE TO LIMITED THROTTLE CONTROL. RESEARCH HAS SHOWN THIS IS A VERY COMMON PROBLEM WITH 2012 TACOMA TRUCKS. *TR

AIR INJECTION SYSTEM FAILING PUTTING TRUCK INTO LIMP MODE (CODES P2442 AND P2440) AN UNSAFE DRIVING CONDITION. COMMON LOW MILEAGE PROBLEM THAT IS NOT COVERED BY EITHER FEDERAL EMISSIONS WARRANTY OR POWER TRAIN WARRANTY. *TR

DRIVING AT 55 MPH, CHECK ENGINE LIGHT CAME ON AND VEHICLE WENT INTO LIMP MODE. DECREASE IN SPEED AND POWER. MECHANIC COMPUTER SHOWED FAULT CODES 2440 AND 2442. SECONDARY AIR INJECTION PUMP AND VALVES FAILURE. THROUGH RESEARCH HUNDREDS OF TACOMA OWNERS ARE HAVING SAME PROBLEM. FAULTY MANUFACTURERS PART CAUSING VEHICLES TO GO INTO LIMP MODE. *TR

CHECK ENGINE AND TRAC OFF LIGHT ON WHEN STARTING VEHICLE. NOTICED IT WOULD NOT ACCELERATE MUCH AT 20MPH (LIMP MODE?), SO I PULLED OVER AND CALLED DEALER SERVICE AND TOOK FOR DIAGNOSIS. LUCKILY NOT IN HEAVY TRAFFIC OR BUSY STREET, JUST NEIGHBORHOOD. DEALER REPAIRED SECONDARY AIR INJECTION PUMP AND VALVES FOR $2,000. INDICATED NOT A NORMAL REPAIR. INTERNET SEARCH PROVED OTHERWISE AS ITS A EXTENSIVE ISSUE WITH PRIOR MODELS OF TOYOTA VEHICLES AND 2012 TACOMA'S.

SECONDARY AIR INTAKE SYSTEM FAILED DURING START UP. THE VEHICLE IS DRIVABLE BUT DANGEROUS CEL IS ON AND COMPUTER LIMITS THE VEHICLES POWER. THIS IS RELATED TO EMISSIONS. THE VEHICLE WAS 8 DAYS OUT OF WARRANTY WITH 39500K MILES. THIS SYSTEM HAS BEEN A PROBLEM IN OTHER TOYOTA VEHICLES INCLUDING THE 2012 V6 TACOMA. COST OF REPAIR ESTIMATED AT $1950.00

THE CHECK ENGINE LIGHT AND TRAC OFF LIGHTS CAME ON. THE VEHICLE LOST POWER AND NEARLY DID NOT MAKE IT UP A HILL. CODES WERE READ AT A LOCAL AUTO PARTS STORE INDICATING P2440 & P2442. TOOK IT TO THE TOYOTA DEALER WHO CONFIRMED THE CODES AND INDICATED THE SECONDARY AIR INJECTION VALVES WERE BURNED OUT AND STUCK OPEN, REQUIRING REPLACEMENT. THE PARTS WERE REPLACED AT A SIGNIFICANT COST TO ME. AN INTERNET SEARCH REVEALED THAT THIS CONDITION IS COMMON TO THE 2012 TOYOTA TACOMA. A SIMILAR ISSUE INVOLVING THE TOYOTA TUNDRA WAS ALSO DISCOVERED. *TR

I LEFT THE GYM YESTERDAY AND THE TRUCK HAD NO POWER AND WOULD NOT ACCELERATE, I ALMOST GOT T-BONED PULLING INTO TRAFFIC. I LOOKED DOWN AND THE CHECK ENGINE LIGHT WAS ON AS WELL AS THE TRACTION CONTROL LIGHT. RAN BY AUTOZONE AND HAD THEM SCAN THE OBD AND IT SHOWED P2442 ERROR CODE. I TOOK IT BY THE DEALER THIS MORNING AND THEY SAY BOTH BY-PASS VALVES ARE GONE AS WELL AS THE AIR INJECTION PUMP. ESTIMATE WAS $1,798. THIS IS A 2012 MODEL AS SEEMS TO BE THE NORM WITH THIS FAILURE. BUT WITH ONLY 35K MILES. I TOLD THEM THIS WAS RIDICULOUS FOR THIS TO HAPPEN ON THIS MODEL WITH THIS LOW OF A MILEAGE AND THAT THIS SHOULD BE COVERED UNDER WARRANTY. THE SERVICE REP SAID IT WASN'T AND HER HANDS WERE TIED. I TALKED TO THE SERVICE MANAGER AS WELL AS THE GM. SO FAR TOYOTA HAS REFUSED TO RESOLVE THIS ISSUE IN A FAIR MANNER. THIS IS A KNOW PROBLEM BY TOYOTA ON THE 2012 MODEL TACOMA'S. THEY ARE HAVING THE SAME ISSUE ON THE TUNDRA TRUCKS AND ARE COVERING THESE PARTS UNDER A 150,000 MILE EXTENDED WARRANTY. THERE ARE MANY REPORTS OF THIS SAME FAILURE WITH THE TACOMA'S BUT TOYOTA SO FAR IS REFUSING TO ADDRESS THIS ISSUE. WHEN THIS FAILURE DOES OCCUR THE VEHICLES GO INTO "LIMP" MODE. THIS CAN BE VERY DANGEROUS IF UNEXPECTEDLY YOU LOOSE POWER OR SPEED WHILE MERGING, PULLING INTO TRAFFIC OR ON THE FREEWAY. *TR

SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE ERROR CODE P2440 AND P2442 TRUCK IS NOW IN LIMP MODE AND UNDRIVEABLE

AIR INJECTION PUMP AND DIVERTER VALVE ASSEMBLY FAILED CAUSING VEHICLE TO ENTER LIMP MODE. VEHICLE WAS MOVING AT LOW SPEED FROM A FRESH START UP. TOYOTA HAS RECOGNIZED THE ISSUE ON THE TUNDRA TRUCK AND EXTENDED 150K MILE WARRANTY ON THE PART. THEY HAVE NOT EXTENDED THE SAME CONSIDERATION ON THE TACOMA. BASED ON RESEARCH AND DISCUSSION WITH DEALER IT IS A KNOWN ISSUE ON THE 2012 TACOMA. COST TO REPAIR I WAS $1484.14. *TR

I GOT THE ENGINE LIGHTS ON IN THE MORNING STARTING THE TRUCK ON NOV 3, AND TRUCK WENT INTO LIMP MODE. GOT IT HOME AND LET IT SIT FOR A BIT AND THEN IT SEEMED TO BE OKAY ACCELERATING BUT THE ENGINE LIGHTS WERE STILL ON. TOOK IT TO TOYOTA AND WAS READING THE DREADED P2442 SECONDARY AIR INJECTION SYSTEM CODE. THEY CLEARED THE CODE AND DROVE IT AROUND; CLEARED AGAIN THEY DEEMED IT OKAY AND CHARGED ME $60 FOR THE CODE READ. LEAVE TO DRIVE TO WORK AGAIN THIS MORNING AND BAM, THE LIGHTS BACK ON AND THE THING IS BACK INTO LIMP MODE WITH BARELY ANY POWER TO THE ENGINE. HAD TO DRIVE THIS TRUCK IN THIS UNSAFE CONDITION BACK TO MY HOUSE. I READ SO MUCH ONLINE ABOUT HOW MANY PEOPLE ARE AFFECTED WITH THIS SAME DEFECTIVE PART AND TOYOTA QUOTED ME $2300 CAD + 13% TAX TO FIX IT AND REPLACE THE SECONDARY AIR INJECTION PUMP/VALVE. NOT COVERED UNDER ANY WARRANTY NOR MY EXTRA CARE PROTECTION PLAN I PAID FOR.

MY 2012 TOYOTA TACOMA CHECK ENGINE AND TRACTION CONTROL LIGHT CAME ON. TRUCK WENT IN LIMP MODE, WHICH WAS VERY UNSAFE. TOOK MY TRUCK TO AUTO ZONE TO HAVE THE CODES READ. MY TRUCK CODE WAS P2442. AIR INJECTION SYSTEM SWITCH VALVE STUCK OPEN. THIS IS A KNOWN ISSUE TO TOYOTA TUNDRA TRUCKS BUT NOT FOR THE TACOMA.

DRIVING ON THE STREET TO WORK ONE MORNING, THE TRAC OFF AND CHECK ENGINE LIGHTS BOTH SUDDENLY APPEARED. I THEN NOTICED THAT MY TRUCK WAS NOT ABLE TO ACCELERATE PAST ~40 MPH. GOING UPHILL, MY TRUCK WAS LIMITED TO ONLY ~20 MPH. MY TRUCK WENT INTO THIS "SAFE MODE." I CONNECTED AN OBD DEVICE AND THE CAME UP WITH THE FOLLOWING TWO CODES: P2440 AND P2442. THE CODES REFER TO "SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE STUCK OPEN" FOR BANKS 1 AND 2, RESPECTIVELY. I DID SOME FURTHER RESEARCH ON THE CODES, AND IT TURNS OUT THIS IS A COMMON ISSUE ON 2012 TACOMAS. APPARENTLY, THE VALVE FOR THE SECONDARY AIR INJECTION SYSTEM IS STUCK OPEN DUE TO MOISTURE AND/OR CARB BUILD UP. I BELIEVE THIS IS A DESIGN/ENGINEERING ISSUE. PART REPLACEMENT COSTS ~$480 FOR EACH VALVE ASSEMBLY. LABOR CAN RANGE ANYWHERE BETWEEN $200-$500. IF THIS IS A KNOWN ISSUE THAT IS COMMON TO A LOT OF 2012 TACOMAS, THEN I BELIEVE TOYOTA SHOULD BE PROACTIVE SUCH AS RELEASING AN OFFICIAL RECALL OR EVEN IMPLEMENT SOME TYPE OF REIMBURSEMENT. NOTE THAT MY TRUCK HAS ~80,000 MILES ON IT. AS AN OWNER, I SHOULDN'T SUFFER FROM AN ENGINEERING DESIGN FLAW AND I SHOULDN'T BE FINANCIALLY RESPONSIBLE TO REPAIR/FIX THE ISSUE. ANY ASSISTANCE WOULD BE HELPFUL. THANK YOU AND HAPPY HOLIDAYS! *TR

ENGINE CODE P2442 & P2440: SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE BANK 2. TRUCK ONLY HAS 40,000 MILES ON IT. DEALER WHAT $1800.00 TO MAKE REPAIRS. TOYOTA HAS A PROBLEM WITH THE PART AND THEY NEED TO FIX IT. NOTHING LIKE HAVING NUMEROUS FAILURES AND LEAVING THE CUSTOMER TO PAY FOR THE POOR ENGINEERED PART. *TR

CHECK ENGINE AND TRAC OFF LIGHTS CAME ON. VEHICLE ACCELERATION BECAME VERY SLUGGISH. I FELT THE VEHICLE BECAME A SAFETY HAZARD AS IT HAD ALMOST NO ACCELERATION . MERGING INTO TRAFFIC BECAME DANGEROUS BECAUSE OF LACK OF ACCELERATION. HAD LOCAL SHOP CHECK TRUCK AND ERROR CODES RETURNED WERE P2440 AND P2442 WHICH THEY SAID INDICATED SECONDARY AIR INJECTOR PUMP NEEDS TO BE REPLACED. EST CHARGE ABOUT $2000!

MY CHECK ENGINE LIGHT CAME ON AND MY VEHICLE ENTERED "LIMP MODE," WHICH KEEPS THE CAR UNDER ABOUT 35MPH AND PREVENTS IT FROM ACCELERATING QUICKLY. THE CEL READ AS A SECONDARY AIR INTAKE SYSTEM PROBLEM (P2440 AND P2442). JUDGING BY THE MULTITUDE OF SIMILAR COMPLAINTS I HAVE FOUND, THIS IS A SYSTEMIC PROBLEM THAT TOYOTA REFUSES TO RECTIFY FOR TACOMAS BUT HAS ALREADY ADMITTED TO FOR TUNDRAS. THIS IS A SERIOUS DANGER TO DRIVERS IF THE VEHICLE ENTERS "LIMP MODE" WHILE THEY ARE DRIVING THROUGH AN INTERSECTION OR IN HEAVY TRAFFIC. IT ISEEMS ALSO RIDICULOUS FOR TOYOTA TO EXPECT TACOMA OWNERS TO SPEND THOUSANDS OF DOLLARS TO FIX THEIR POORLY DESIGNED PART, ESPECIALLY CONSIDERING THE PART IS NOT VITAL TO THE PERFORMANCE OF THE ENGINE.

2012 WITH 78,000 MILES, THREW CODES P2440, P2442. SAME AS EVERY OTHER TACOMA OWNER IN THIS YEAR RANGE. BAD VALVES AND PUMP ON THE SECONDARY AIR INJECTION UNIT. COST TO REPAIR AROUND 1,000 DOLLARS DOING THE WORK MYSELF. VERY DISAPPOINTED AS THIS IS MY THIRD TACOMA AND HAD PLANNED ON KEEPING THIS ONE FOR A LONG TIME.

57,000 MILES ON TRUCK WENT INTO LIMP MODE, P2440 AND P2442 CODE SHOWED SECONDARY AIR INJECTION VALVE DEALER QUOTED $2000, SAID THEY WOULDN'T COVER ANYTHING

THE SECONDARY AIR INJECTION PUMP FAILED AT 62,000 MILES. FOR SPECIFICS IT SHOWED THE CODES P2440 AND P2442. THIS WAS KNOWN PROBLEM ON THE PREVIOUS MODEL TUNDRAS, THE SERVICE MGR AT RODLAND TOYOTA SAID THEY HAD ALREADY REPLACED THREE PUMPS ON TRUCKS OF THE SAME YEAR THAT WEEK.

THE SECONDARY INJECTION PUMP WENT OUT.

I WAS DRIVING ON A50MPH HIGHWAY AN CHECK ENGINE LIGHT COMES ON AND TRUCK SLOWS TO 40MPH WONT GO ANY FASTER.

THIS IS A PROBLEM WITH THE SECONDARY AIR INJECTION PUMP AND SOLONOID...IT LEFT ME STRANDED ON THE ROADSIDE...24000 MILES ON A TRUCK IS NOT EVEN BROKE IN..RELIABILITY?..I HANDLED IT..ONLY BECAUSE IVE BEEN A MECHANIC FOR 25 YEARS...WHAT IF IT WAS MY WIFE AND KIDS BROKE DOWN IN GETTO TOWN...THIS IS A HUGE PROBLEM FOR MANY AND IS SO COMMON..IVE CLEARED THE CODES SEVERAL TIMES BUT THEY ALWAYS REAPPEAR...THIS IS A DEFINATE RECALL...MAKE IT SO...24000 9N A TRUCK AND I CANT DRIVE IT...MY LOYALTY IS FADING FAST...TRY TO IMAGINE DRIVING YOUR TRUCK DOWN A ST.LOUIS 6 LANE FREEWAY AND YOUR TRUCK SAYS...NOPE YOU STAYING HERE..ON THE SIDE OF THE ROAD...DONT GET OUT...YOULL GET RAN OVER...MAYBE TOYOTA SHOULD HAVE A DISPLAY ON THE INFO CENTER CONCOLE THAT TELLS YOU THAT...AND THEN WISHES YOU GOOD LUCK...

AIR PUMP AND VALVES ON THE EMISSION SYSTEM FAILED. TRUCK WENT INTO LIMP MODE WITH LIMITED ACCELERATION AND SPEED. THIS IS A SAFETY HAZARD. THIS IS A COMMON PROBLEM ON 2012 TACOMA. TUNDRA AND SEQUOIA VEHICLES HAVE HAD THE SAME EXACT ISSUE AND REPAIRS COVERED BY TOYOTA. HOWEVER, TOYOTA WILL NOT COVER THIS SAME ISSUE ON THE TACOMA.

CODES P2440 & P2442 THESE ARE FOR THE AIR INJECTION SYSTEM ON START UP. THE VALVES FAIL AND THIS IS A EMISSIONS PART. OUT OF WARRANTY AND ONLY HAVE 65,000 MILES. TUNDRA HAD THIS ISSUE AND GOT A 10 YEAR WARRANTY ON THE COMPONENTS.

TL* THE CONTACT OWNS A 2012 TOYOTA TACOMA. AFTER THE VEHICLE WAS STARTED, THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE SECONDARY AIR INJECTION VALVE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 56,000. THE VIN WAS NOT PROVIDED.

TL* THE CONTACT OWNS A 2012 TOYOTA TACOMA. WHILE DRIVING 55 MPH, THE VEHICLE SEIZED AND THE SPEED DECREASED TO 20 MPH. THE VEHICLE STALLED IN THE MIDDLE OF THE HIGHWAY. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE AIR PUMP NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACURER WAS NOT NOTIFIED OF TH FAILURE. THE FAILURE MILEAGE WAS 68,000. THE VIN WAS NOT AVAILIABLE.

ENGINE OIL LIGHT COMES ON AND FLASHES A FEW TIMES AFTER STARTUP, BEYOND THE NORMAL TIME FOR ALL THE OTHER LIGHTS WHILE IN THE STARTING MODE, DEALER COULD NOT DUPLICATE

THE TRUCK STARTED TO MAKE A RATTLING NOISE UNDER THE HOOD ON THE DRIVERS SIDE WHEN REACHING 15MPH. TOOK IT TO DEALER TO HAVE IT EXAMINED. THEY SAID TO TRY DIFFERENT GAS NOT CHEAP GAS. "I WAS ALREADY USING SHELL GAS" BUT I DID WHAT THEY SAID. STILL MAKING THE NOISE NOW FROM 20-40MPH. TAKE IT BACK TO DEALER NOW THEY TAKE A TEST DRIVE WITH MYSELF TO VERIFY THE NOISE. COMES BACK THAT IT HAS A TAS CASE# THERE'S NOTHING THEY CAN DO ABOUT IT. I CALL TO FILE A COMPLAINT TO FIND OUT THERE IS NO REPAIR AND THEY WILL NOT TOUCH IT TILL IT BECOMES A RECALL. JUST TOOK IT BACK FOR THE THIRD TIME BECAUSE THE RATTLING IS LOUDER AND LONGER. STILL DID NOTHING. THE RATTLING CAN GET SO LOUD THAT IT SOUNDS LIKE SOMETHING IS GOING TO FALL OUT FROM UNDER THE HOOD. *TR
