2012 Toyota Tacoma Complaint Log

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.

I WAS PULLING OUT ON TO THE HIGHWAY AND MY TRUCK FAILED TO EXCEED 30 MPH WITH ONCOMING TRAFFIC WHICH NEARLY CAUSED AN ACCIDENT. UPON INSPECTION BY MY TOYOTA DEALERSHIP, THEY EXPLAINED THAT MY SECONDARY AIR INJECTION VALVES WERE STUCK OPEN (P2440, P2442) WHICH CAUSED THE TRUCK TO LOSE ALL POWER. I WAS THEN TOLD THAT SINCE I AM NO LONGER UNDER WARRANTY (MY TRUCK IS ONLY 5 YEARS OLD WITH 48,000 MILES ON IT) THAT TOYOTA WOULD NOT COVER THE 2,000 DOLLAR COST TO HAVE THE PART REPLACED. UPON FURTHER RESEARCH, COUNTLESS OTHERS WERE HAVING THE SAME ISSUE. THE TOYOTA TUNDRA ALSO HAD THIS ISSUE AND AN EXTENDED WARRANTY WAS OFFERED FOR THOSE VEHICLES. SINCE TOYOTA KNOWS THIS IS AN ISSUE IT IS MY BELIEF THAT THEY SHOULD STAND BY THEIR PRODUCT AND FIX THE DEFECTIVE PART WHICH IS A HUGE SAFETY ISSUE AS I FOUND OUT. FURTHERMORE, THERE IS NO REASON THIS EMISSIONS PART SHOULD EVER SHUT DOWN THE POWER TO THE TRUCK WHILE DRIVING. THANK YOU FOR YOUR TIME.

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.

SECONDARY AIR INJECTION SYSTEM FAILURE CAUSED MY VEHICLE TO ENTER LIMP MODE IN A HIGH SPEED/HIGH TRAFFIC AREA. "LIMP MODE" RENDERS THE VEHICLE INCAPABLE OF SPEEDS HIGHER THAN 30 MPH. CAUSING A HAZARD TO OTHER MOTORISTS, I EXITED THE HIGHWAY AS QUICKLY AS POSSIBLE. UPON RESEARCHING THE TOPIC I CAN PLAINLY SEE THIS IS SOMETHING THAT IS QUITE COMMON WITH MY PARTICULAR VEHICLE. HOWEVER, OTHER MODELS MADE BY THE SAME MANUFACTURER ARE BEING RECALLED AND REPAIRED WHILE THE MODEL I OWN IS NOT. IN ADDITION TO MODEL, THE YEAR OF MY VEHICLE SEEMS TO BE EXPERIENCING AN UNUSUALLY HIGH VOLUME OF FAILURES. FILING A COMPLAINT HERE IS ONLY APPROPRIATE AND APPROPRIATELY, THE AUTOMOTIVE MAKER SHOULD BE HELD RESPONSIBLE.

I START UP THE TRUCK AND PULL OUT IN TO THE STREET. WHETHER AT AN INTERSECTION OR MAKING A TURN, I PUSH ON THE ACCELERATOR AND NOTHING HAPPENS. THE RPMS DON'T INCREASE, ENGINE MAKES NO SOUND - AND I AM LEFT SITTING IN THE MIDDLE OF THE ROAD. I PUSH THE ACCELERATOR TO THE FLOOR AND EVENTUALLY THE ENGINE COMES TO LIFE AND THE TRUCK MOVES FORWARD. HAPPENS MORE OFTEN THAN NOT WHEN THE VEHICLE IS "COLD" - WITHIN THE FIRST 20-30 MINUTES OF OPERATION. THE ACCELERATOR IS NOT LINKED DIRECTLY TO THE ENGINE THROUGH A CABLE BUT IS A DRIVE BY WIRE. I HAVE MAINTAINED MY TACOMA METICULOUSLY SINCE PURCHASE INCLUDING TUNE UPS, OIL CHANGES, ETC. I HAVE CLEANED THE MASS AIR FLOW SENSOR WITH NO CHANGE. THE PROBLEM STILL PERSISTS. IT IS VERY DANGEROUS TO BE IN THE MIDDLE OF AN INTERSECTION WITH A VEHICLE THAT HAS LOST POWER.

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 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).

THE ABS ACTUATES PREMATURELY DURING CORNERING ON FREEWAY ON/OFF RAMPS AND IN CORNERS RESULTING IN SUSPENSION DIVE, AN UNDER STEER CONDITION, AND LOSS OF VEHICLE CONTROL. THIS OCCURS WHEN THE VEHICLE IS IN MOTION AT POSTED SPEED LIMITS ON DRY PAVEMENT. I HAVE CONTACTED TOYOTA/BEEN TO THE DEALERSHIP SEVERAL TIMES ABOUT THIS ISSUE WITH NO RESOLUTION. THEY CLAIM THAT THE LEVELING KIT AND AT TIRES ARE TO BLAME. I RELATED THAT I HAD THIS ISSUE WITH THE TRUCK WHEN IT WAS BRAND NEW WITH NO MODIFICATIONS.

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

HORN QUIT WORKING, ONLY WORKS WHEN THE WHEEL IS TURNED TO THE LEFT, FUSES ARE GOOD AND SO ARE THE RELAYS.

CHECK ENGINE LIGHT ON, TRAC OFF LIGHT ON, ENGINE POWER WEAK CHECK ENGINE CODE- P2441. THIS HAS BEEN A COMMON ISSUE WITH TOYOTA SUVS, AND TRUCKS! CAR IS PUT INTO LIMP MODE. EXTENDED WARRANTY ON TUNDRA WITH SAME PART PROBLEM. NOT TACOMA. SHAMEFUL AND DANGEROUS FOR TACOMA OWNERS.

WHILE COMMUTING TO WORK THE ENGINE LIGHT AND TRACTION CONTROL LIGHT CAME ON, CAUSING MY TRUCK TO SLOW DOWN, VERY SLOW. IT WOULD NOT LET ME ACCELERATE AND DISABLED MY PROGRESS TO AROUND 2000 RPMS. THIS COULD HAVE BEEN A VERY SERIOUS OR A DANGEROUS SITUATION ESPECIALLY IF I WAS TOWING A LOAD OR IN A MAJOR TRAFFIC SITUATION. CODES - 2440 AND 2442 WERE THE CAUSES OF THIS SCARY ACCOUNT.

SECONDARY AIR PUMP FAILED AT 47,000 MILES, SHORTLY AFTER WARRANTY EXPIRED. IT FAILED AS I WAS PULLING OUT ONTO A MAJOR FAST-MOVING HIGHWAY AND PROMPTLY WENT INTO "LIMP" MODE, LIMITING ACCELERATION. IT TOOK OVER A HALF MILE TO GET THE VEHICLE TO 40 MPH. MEANWHILE, VEHICLES BEHIND ME WERE BRAKING ABRUPTLY TO AVOID COLLIDING WITH ME. AS I UNDERSTAND IT THE SECONDARY AIR PUMP IS PART OF THE EMISSION CONTROL SYSTEM AND I DON'T BELIEVE THAT THIS SHOULD EFFECT THE PERFORMANCE OF THE ENGINE IN THIS MANNER. THIS SEEMS MORE LIKE A SOFTWARE INDUCED FAILURE, WHICH, IN THIS CASE, CAUSED A POTENTIALLY DANGEROUS SITUATION. AFTER SOME BACK AND FORTH TOYOTA AGREED TO REFUND ME 1/2 OF THE $2500 THAT I WAS CHARGED FOR THE REPAIR. UPON SEARCHING THE INTERNET, I FOUND DOZENS OF INSTANCES OF THIS FAILURE ON 2012 TACOMA'S WITH SIMILAR MILEAGE.

SECONDARY AIR INJECTION ERROR CODES P2440, P2441,P2442. LOSS OF POWER DUE TO AIR INJECTOR STUCK. VEHICLE WILL NOT ACCELERATE BEYOND 20-30 MPH. THIS IS AN EMMSISIONS REQUIREMENT BUT WARRANTIES ON TACOMAS WILL NOT COVER BEYOND 3YRS/35K MILES. TUNDRAS HAVE TUNDRAS HAVE SAME KNOWN ISSUES AND TOYOTA INCRWASED WARRANTY TO 10 YRS/150K MILES. SUDDEN LOSS OF POWER IS ALSO A SAFETY ISSUE WHILE DRIVING ON HIGHWAYS. OWNERS ARE PAYING THOUSANDS IN REPAIRS FOR SOMETHING THAT SHOULD BE COVERED UNDER WARRANTY.

DRIVING AT HIGH WAY SPEED; THE ABS LIGHT, PARKING BRAKE LIGHT, TRACTION LIGHT, LOST POWER TO WINDOWS, A/C, RADIO, POWER STEERING, ENGINE WAS RUNNING ROUGH, THEN THE CHECK ENGINE LIGHT CAME ON. COULD BE A SAFETY ISSUE OF CONTROL OF VEHICLE FOR DRIVERS NOT PAYING ATTENTION. TOYOTA DEALER SAID THE ROOT CAUSE WAS A BAD CELL IN BATTERY THAT CAUSED THE IGN#2 FUSE TO BE BLOWN. THESE BATTERIES HAVE KNOWN ISSUES TO BE BAD FROM THE FACTORY. REPORTED EARLIER ABOUT 30000 MILES THE FACTORY BATTERY WOULD NOT START VEHICLE AND DEALER SAID THEY REPLACED BECAUSE OF A BAD CELL. I OWN A 2008 TOYOTA TACOMA ALSO , SAME MODEL AND MAKE AS BEING REPORTED AND THAT BATTERY HAS BEEN REPLACED 2 TIMES FOR SAME REASON.

AT START UP "CHECK ENGINE" AND "TRAC OFF" LIGHTS WERE ON. TRUCK HAD NO ACCELERATION AND TRANSMISSION WOULD NOT SHIFT. I TOOK THE CAR TO THE DEALERSHIP AND DIAGNOSTIC CODES P2440 AND P2442 WERE DETECTED. DEALER HAD TO REPLACE THE AIR INJECTION SYSTEM BANK 1 AND BANK 2. DURING RESEARCH, I DISCOVERED NUMEROUS OTHER OWNERS OF 2012 TACOMA'S COMPLAING ABOUT THE SAME ISSUE. SOME EVEN LOST POWER WHILE DRIVING. ALSO, THE TUNDRA APPARENTLY HAD A SIMILAR ISSUE BEING REPORTED

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.

I HAVE 27,000 MILES ON MY TRUCK AND THE REAR DIFFERENTIAL IS DEFECTIVE. I AM AFRAID IT WILL LOCK UP AT HIGH SPEEDS, 55 MPH + AND CAUSE AN ACCIDENT!! TOYOTA WON'T FIX IT

WHEN THE VEHICLE IS IN MOTION THE BACK END CREAKS LOUDLY OVER THE REAR TIRES. THIS IS ESPECIALLY NOTICEABLE AT LOW SPEEDS AS THE TRUCK BOUNCES OVER THE ROAD. WHEN THE VEHICLE IS STATIONARY AND I AM IN THE BED OR ON THE TAILGATE, THE TRUCK BOUNCES EASILY AND CREAKS LOUDLY OVER THE REAR TIRES. I HAD NEW LEAF SPRINGS INSTALLED IN JULY 2018 BECAUSE THAT IS WHAT MY MECHANIC DIAGNOSED THE PROBLEM TO BE. NOW, LESS THAN A YEAR LATER THE SAME ISSUE PERSISTS. THE SOUND IS METAL IS RUBBING ON METAL, AND I SUSPECT ANOTHER PART OF THIS VEHICLE'S SUSPENSION IS BAD.

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.

I HAVE CHECK ENGINE LIGHT ON AND THE TRAC OFF LIGHT ON. THIS COMMON PROBLEM WIYHE TUNDRA MODEL. ALOT OF TACOMA OWNER HAVE SAME PROBLEM BUT TACOMA DOE NOT HAVE EXDENDED WARRANTY LIKE THA TUNDRA. MY TRUCK ONLY HAVE 59K MILES IT'S ONLY 5YEARS AND 3 MONTHS OLD THEY SAID WON'T COVER THE PROBLEM. PROBLEM 1 SECONNDARY INJECTION SYSTEM VALVE I HAVE TO CODE P2440 P2442.

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.

P2442 TOYOTA SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE STUCK OPEN BANK 2 I HAVE GOT THIS CODE THREE TIMES NOW AND THE SECONDARY AIR INJECTION PUMP AND VALVES WILL HAVE TO BE REPLACED. THERE IS 33,282 MILES ON THE TRUCK RIGHT NOW. MANY, MANY, MANY COMPLAINTS ONLINE ABOUT THIS ISSUE BUT TOYOTA IS IGNORING IT. $1900 FIX IS VERY STEEP FOR A TRUCK WITH 33K MILES.

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.

VEHICLE WAS IN MOTION ON RAINY, WET HIGHWAY WHEN CHECK ENGINE LIGHT WENT ON AND TRACTION CONTROL WAS SHUT OFF. THE SECONDARY AIR INJECTION SWITCHING VALVE IS APPARENTLY STUCK CLOSED, WHICH FOR SOME REASON SHUTS OFF THE TRACTION CONTROL. IT IS MY UNDERSTANDING FROM SPEAKING WITH OTHER TACOMA AND TUNDRA OWNERS THAT HAD THE VALVES GOTTEN STUCK OPEN, THE VEHICLE GOES INTO "LIMP MODE" WHICH AUTOMATICALLY DECREASES SPEED TO 20MPH. OBVIOUSLY, EITHER OF THESE OCCURRENCES ARE PARTICULARLY UNSAFE IN RAINY AND WET CONDITIONS, AND THE DECREASE IN SPEED IS UNSAFE DURING ANY HIGHWAY TRAVELING. THIS IS APPARENTLY A BIG ENOUGH ISSUE ON THE TUNDRA MODELS FOR TOYOTA TO EXTEND THE WARRANTY TO 150,000MI, YET THEY HAVE DONE NOTHING FOR THE TACOMAS WHICH HAVE AN IDENTICAL SYSTEM AND PARTS.

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.

THE SECONDARY AIR INTAKE SYSTEM GOES OUT FAIRLY QUICKLY. MY VEHICLE IS AT 72,500 MILES. THIS CAUSES THE CAR TO GO INTO "LIMP" MODE WHICH MAKES THE CAR GO A MAXIMUM OF 40MPH. THIS CAN BE VERY DANGEROUS IF IT WERE TO KICK IN WHILE ENTERING THE HIGHWAY. IT IS AN EMISSIONS ITEM, BUT TOYOTA IS NOT COVERING IT UNDER THE EMISSIONS WARRANTY.

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?

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 PUMP. RECEIVING P2442 CODE AND TRUCK IS GOING IN TO LIMP MODE

TL* THE CONTACT OWNS A 2012 TOYOTA TACOMA. WHILE DRIVING APPROXIMATELY 55 MPH, THE VEHICLE LOST POWER AND THEN IMMEDIATELY REGAINED POWER. THE CHECK ENGINE WARNING INDICATOR ILLUMINATED. THE FAILURE RECURRED TWICE. THE CONTACT COASTED THE VEHICLE TO A SERVICE STATION, RESTARTED IT, AND WAS ABLE TO DRIVE. WHILE DEPRESSING THE ACCELERATOR PEDAL, THE VEHICLE WOULD NOT ACCELERATE PAST 25 MPH. THE VEHICLE WAS TAKEN TO TOYOTA OF POWAY (13631 POWER RD, POWAY, CA 92064) WHERE IT WAS DIAGNOSED THAT THE AIR SYSTEM VALVE NEEDED TO BE REPLACED. THE CONTACT WAS ALSO INFORMED THAT THE AIR INJECTION PUMP MAY EVENTUALLY NEED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND THE CONTACT WAS REFERRED TO NHTSA. THE APPROXIMATE FAILURE MILEAGE WAS 133,472.

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.

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??

WHILE DRIVING ON THE FREEWAY MY VEHICLE LOST PARTIAL POWER TO THE ENGINE. I TOOK IT TO THE SERVICE CENTER AND THEY RAN A DIAGNOSTIC SAYING THAT I HAVE A "FAILED ENGINE AIR SYSTEM PUMP AND VALVE." IT WAS VERY DANGEROUS LOOSING CONTROL OF THE SPEED OF THE VEHICLE ON THE FREEWAY.

P2442

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.

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.

LIKE MANY OTHERS, MY 2012 TACOMA SUDDENLY LOST POWER ON THE HIWAY. REFUSED TO GO ABOVE 40 OR SO MPH. OTHER CARS HAD TO SLAM ON BRAKES TO AVOID ME. TOOK IT TO THE DEALER AND THEY WANTED NEARLY $2000.00 TO REPLACE THE SAME PARTS THAT HAVE BEEN IDENTIFIED IN THE TUNDRAS AS BEING DEFECTIVE. SECONDARY AIR INJECTION STUCK OPEN. THE CODES ARE P2440 AND P2442. THIS IS A SAFETY HAZARD AS THE VEHICLE SUDDENLY LOSES POWER. TOYOTA ISSUED A TSB AND EXTENDED THE WARRANTY TO 150K FOR THE TUNDRA BUT NOT THE TACOMA. SAME PARTS! MY TACOMA WAS IN MOTION WHEN SUDDENLY LOST POWER. THIS IS A SAFETY ISSUE. CHECK OUT CARCOMPLAINTS.COM

CHECK ENGINE LIGHT ON, TRAC OFF LIGHT ON, ENGINE POWER WEAK

THE TRAC OFF AND CHECK ENGINE LIGHTS CAME ON YESTERDAY AND I WAS UNABLE TO ACCELERATE OVER 40MPH. I RAN A DIAGNOTICS TEST ON IT AND IT CAME BACK P2440 AND P2442 WHICH IS THE SECONDARY AIR INJECTION SYSTEM FAILURE. ONE OF THE VALVES IS STUCK OPEN.

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.

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.

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.

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.

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.

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.

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.

SECONDARY AIR VALVE STICKS CAUSING LOSS OF POWER,,EMISSION SYSTEM WHILE DRIVING AND STAYS ON.

ERROR 2440/2442 CAME UP A FEW DAYS AGO WHEN STARTING THE TRUCK TO GO TO WORK(COOL MORNING) - SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE STUCK OPEN BANK 1/2. I FIRST NOTICED THAT IT INDEED PUT THE TRUCK INTO LIMP MODE, WHICH CAUSES THE ENGINE TO DECREASE POWER SO I COULD HARDLY ACCELERATE.(PRESSURE SENSOR IN EXHAUST WENT OFF BECAUSE VALVES WERE STUCK OPEN) I KNEW EXACTLY WHAT THE PROBLEM WAS DUE TO MANY HAVING THE SAME ISSUES ON A TACOMA FORUM I AM ON.(ALL WITH EARLY 2012'S, A REDESIGNED PUMP WAS MADE AND INSTALLED ON LATER BUILT 2012S) I TOOK APART THE SYSTEM AFTER GETTING A SHAFT FROM MY LOCAL DEALER SAYING IT WAS UNDER POWERTRAIN WARRANTY.(KNEW IT WAS UNLIKELY AS I HAVE ALMOST 70K MILES, BUT THOUGHT WHY NOT TRY) AFTER READING ABOUT OTHER'S WAYS OF SOLVING THE ISSUE, I TOOK APART BOTH THE AIR PUMP AND VALVE ASSEMBLY TO INSPECT THEM. I WAS AMAZED TO FIND A SOAKED AIR FILTER WITH WATER SITTING IN THE PLASTIC MOLDING UNDER IT, I ALSO FOUND THE RUBBER HAD BEEN BURNT UP IN THE VALVE ASSEMBLY, ALONG WITH DEPOSITS DUE TO MOISTURE.(PICTURES ATTACHED) FROM WHAT I HAVE READ, AND WHAT I HAVE SEEN, TOYOTA INSTALLED THIS DEFECTIVE SYSTEM ON EARLY 2012 TACOMA'S BEFORE A REDESIGNED PUMP(NOT SURE ON VALVES) AND PROGRAMMING THAT IS SUPPOSED TO RUN THE AIR PUMP AFTER THE ENGINE SHUTS OFF TO GET RID OF THE MOISTURE. I BOUGHT NEW VALVES FOR $479, BUT WILL ALSO HAVE TO BUY A BYPASS FOR $350 BECAUSE I KNOW THE AIR PUMP WILL STILL BRING IN MOISTURE AND CAUSE THE VALVES TO FAIL AGAIN, THIS BYPASS ALLOWS THE PUMP/VALVES TO COMMUNIATE TO ECU THAT THEY RUN OK BUT THE AIR PUMP NEVER RUNS. TOYOTA ISSUED A TSB FOR TUNDRA'S AND SEQUIOA'S FOR THE SAME REASON, YET THEY ARE IGNORING TACOMAS.(ATTACHED PDF) ALSO JUST NOTICED ON THIS TSB THEY WERE VERY QUICK ABOUT ISSUING IT AS WELL, CAN'T SEE HOW THEY DIDN'T KNOW THAT TACOMA'S HAD THE SAME SYSTEM INSTALLED.
