2012 TOYOTA TACOMA Engine Problems

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...

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....

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...

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.

CODE P2440 AND P2442. AIR INJECTION SYSTEM VALVES ARE STUCK OPEN (RELATED TO EMISSIONS CONTROL UNIT) WHICH CAUSES THE VEHICLE TO GO INTO 'LIMP' MODE ABRUPBTLY. THIS RENDERS THE VEHICLE UNDRIVEABLE, AND CAN OCCUR IN THE MIDST OF DRIVING CAUSING SERIOUS DANGER TO THE DRIVER AND FELLOW DRIVERS ON THE ROAD. TOYOTA IS UNWILLING TO COVER UNDER ANY POWERTRAIN OR EMISSIONS WARRANTY. THIS ISSUE IS PERVASIVE AMONG 2012 TACOMA OWNERS AND TOYOTA REDESIGNED THE SYSTEM AS EARLY AS 2013 WHICH IMPLICATES THEIR KNOWLEDGE OF SUCH A DEFECT.

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.

SECONDARY AIR INJECTION VALVE STUCK OPEN CAUSING LIMP MODE. HAPPENED NEAR VERY DANGEROUS INTERSECTION AND LOST ALL POWER IN TRUCK. AS OTHERS HAVE STATED, TRUCK ONLY HAS 50K MILES AND REQUIRED A $500+ REPAIR (PART ONLY) FOR A COMPONENT OF THE EMISSION SYSTEM WHICH IS ONLY USED ON STARTUP AND INCLUDES A WARRANTY OF ONLY 2 YEARS.

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.

ENGINE/ALL POWER IS LOST WHEN ENGINE HAS REACHED A CERTAIN RPM. CODE READER STATES "CRANKSHAFT POSITION SENSOR "A" CIRCUIT MALFUNCTION".

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

2012 TACOMA WITH 91,000 MILES: WHILE LEAVING WORK AND TRYING TO ACCELERATE ONTO HIGHWAY THE "CHECK ENGINE" AND "TRAC OFF" LIGHTS ILLUMINATED. VEHICLE WENT INTO "LIMP MODE" AND WOULD NOT GO FASTER THAN 35 MPH. I HAD TO QUICKLY PULL OFF THE ROAD AS TO NOT CAUSE AN ACCIDENT. I TOOK VEHICLE TO MAC HAIK TOYOTA AND RECEIVED THE CODE P2445. I HAD TO REPLACE AIR SWITCH VALVE ASSEMBLY $690, AIR W/BRA PUMP ASSEMBLY $813, AIR TUBE GASKETS $132, LABOR $610. TOTAL $2063!!!! FROM RESEARCHING, THIS IS A KNOWN PROBLEM WITH 2012 TACOMAS, AND HAD PREVIOUSLY BEEN AN ISSUE WITH OLDER TUNDRAS, WHICH TOYOTA ISSUED A TSB FOR. TOYOTA REFUSES TO REPAIR THIS UNDER WARRANTY (FEDERAL EMISSIONS) EVEN THOUGH THE FAILED PART IS DIRECTLY TIED TO THE EMISSIONS SYSTEM! "THE SYSTEM IS USED TO PUMP ADDITIONAL AIR INTO THE EXHAUST MANIFOLD UPON STARTUP TO DILUTE THE OVER-RICH CONDITIONS THAT LEAD...

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...

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...

HEADED TO WORK TO FIND CHECK ENGINE LIGHT ILLUMINATED. TRUCK HAS LESS THAN 41,000 MILES. WENT TO AUTOZONE, CODE READER PROVIDED P2442 AND P2440 ERRORS RELATED TO THE SECONDARY AIR INJECTION SYSTEM VALVES. FOLLOWED UP WITH LOCAL TOYOTA DEALER. DEALER RAN DIAGNOSTIC AND FOUND SECONDARY AIR INJECTION SYSTEM VALVES STUCK OPEN IN BANKS 1 AND 2. DEALER WANTS TO REPLACE PARTS 17600-0P040: PUMP ASSEMBLY; 25710-31022: VALVE ASSEMBLY; AND THE 4 RELATED GASKETS, PART 17377-31010. QUOTE WAS FOR ALMOST $2400. AGAIN, THE VEHICLE IS 2012, LESS THAN 41K MILES! RESEARCHING THE TACOMA FORUMS ONLINE, THIS APPEARS TO BE A COMMON PROBLEM WITH THIS GENERATION MODEL AND MORE EVEN MORE SO WITH 2012'S. ONE OF THE DEALER'S SERVICE ADVISORS INFORMED ME THAT THIS IS ALSO A COMMON PROBLEM WITH TUNDRAS. FURTHERMORE, WHILE DRIVING, THE VEHICLE WOULD GO IN AND OUT OF "LIMP MODE" AND I HAD NO WARNING AS TO WHEN IT...

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...

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

2012 TACOMA WITH 37,00 MILES: WHILE LEAVING A PARKING LOT AND TRYING TO ACCELERATE ON TO A BUSY HIGHWAY, (60MPH SPEEDS), TRUCK WOULD NOT ACCELERATE AND "CHECK ENGINE" AND "TRAC OFF" LIGHTS ILLUMINATED. VEHICLE WENT INTO "LIMP MODE" AND WOULD NOT GO FASTER THAN 35 MPH. I HAD TO QUICKLY PULL OFF THE ROAD AS TO NOT CAUSE AN ACCIDENT. IF THIS HAD THIS OCCURRED WHILE TRAVELING AT NORMAL HIGHWAY SPEED (60 MPH+), WOULD DEFINITELY BE IN A WRECK DUE TO THE SUDDEN DOWNSHIFT AND DECELERATION. I TOOK VEHICLE TO LOCAL AUTO PARTS STORE AND RECEIVED THE CODE P2442: SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE STUCK OPEN BANK 2. FROM RESEARCHING, THIS IS A KNOWN PROBLEM WITH 2012 TACOMAS, AND HAD PREVIOUSLY BEEN AN ISSUE WITH OLDER TUNDRAS, WHICH TOYOTA ISSUED A TSB FOR. TOYOTA REFUSES TO REPAIR THIS UNDER WARRANTY (EITHER POWERTRAIN OR FEDERAL EMISSIONS) EVEN THOUGH THE FAILED...

WHEN I WAS LEAVING WORK THE OTHER NIGHT MY 2012 TACOMA WENT INTO LIMP MODE AND PRESENTED THE CEL AND TRAC OFF LIGHTS ON THE DASH. AFTER REVIEWING THE MANY BLOGS ON THE SUBJECT AND TAKING THE VEHICLE TO THE MECHANICS, I HAVE FOUND OUT THAT THE SECONDARY AIR VALVE IS LIKELY STUCK IN THE OPEN POSITION. THE MECHANIC HAS QUOTED ME A PRICE OF $1,142 ($780 FOR THE PART) TO REPLACE THE WHOLE SYSTEM (VALVE NOT SOLD SEPARATELY). I UNDERSTAND THAT THIS IS A COMMON PROBLEM WITH TUNDRAS/SEQUOIAS AND 2012 TACOS. HOWEVER, ONLY THE TUNDRAS ARE UNDER ANY TYPE OF WARRANTY. I BOUGHT A TACOMA BECAUSE THE LAST TWO TOYOTA'S HAVE RUN 300K MILES + WITH REGULAR MAINTENANCE. THIS TYPE OF EXPENSIVE REPAIR DUE TO POOR ENGINEERING IS LUDICROUS AND SHOULD BE A WARRANTY ISSUE. I GUESS TOYOTA WANTS TO BE TERRIBLE LIKE EVERYONE ELSE. GREAT. *TR

CHECK ENGINE LIGHT CAME ON, TRAC OFF LIGHT IS ON. MY TRUCK HAS NO POWER AND IS UNSAFE TO DRIVE. THE DTC IS P2442. SECONDARY AIR INJECTION SYSTEM SWITCH VALVE STUCK OPEN BANK 2. TOYOTA KNOWS THEY HAVE A EMISSIONS ISSUE. MY VEHICLE IS AT THE DEALERSHIP NOW.

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!
