2012 Toyota Tacoma Complaint Log

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

P2440-P2442 ERROR CODE. SECONDARY AIR INJECTION VALVES AND PUMP. A POORLY ENGINEERED PART THAT CONTINUES TO BREAK AND TOYOTA WONT ADDRESS THE ISSUE LIKE IT HAS ON THE TUNDRA & SEQUANA (SP). THEY KNOW THEY HAVE A BAD PART .

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.

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.

I WAS DRIVING TO WORK THIS MORNING AND WHEN ENTERING A HIGHWAY MY TRUCK COMPLETELY STOPPED ACCELERATING AND WOULD NOT GO OVER 40 MPH, ANF WOULD NOT GO OVER 1200 RPMS. I HAVE RESEARCHED THE CODES THAT POPPED UP FROM MY CHECK ENGINE LIGHT, AND HAVE FOUND A TON OF OTHER PEOPLE ARE HAVING THE SAME ISSUE. THE CODE IS P2442, AND INDICATES A FAILED AIR INJECTOR THAT THE MANUFACTURER HAS NOT ISSUED A RECALL OR SAFETY ADVISORY.

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.

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!

TL* THE CONTACT OWNS A 2012 TOYOTA TACOMA. WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE FAILED TO ACCELERATE. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO DAYTON TOYOTA (2291 US-130, DAYTON, NJ 08810, 732-329-9191), BUT THE FAILURE COULD NOT BE DUPLICATED. THE FAILURE RECURRED SEVERAL TIMES AND THE VEHICLE WAS TAKEN BACK TO THE SAME DEALER. THE TECHNICIAN DIAGNOSED THAT THE CLUTCH NEEDED TO BE REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURES AND OFFERED TO COVER THE COST OF THE PARTS WHILE THE CONTACT COVERED THE LABOR COST. THE FAILURE MILEAGE WAS 33,000.

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.

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.

CHECK ENGINE LIGHT AND TRAC OFF APPEARED AND TRUCK ENTERED LIMP MODE. CODES P2440/P2442 ON DIAGNOSTICS. SECONDARY AIR INVERTER FAILED ALONG WITH AIR PUMP. EMISSIONS CONTROL PROBLEMS. TOYOTA DID NOT ACKNOWLEDGE ANY RESPONSIBILITY.

CEL CODE P2442,P2445 DEALERSHIP SAYS THE AIR SWITCHING VALVE NEEDS TO BE REPLACED. I HAVE 75K MILES ON TRUCK. DEALER IS CHARGING ME 1200$

A PROBLEM COMMON TO TOYOTA'S OCCURRED WITH MY VEHICLE. THE SECONDARY AIR INJECTION PUMP FAILED. THE TACOMA DID NOT HAVE SUFFICIENT POWER AND WOULD NOT REACH CERTAIN RPM'S. THE BILL IS $2,500. THE DEALERSHIP TOLD ME IT HAPPENS QUITE OFTEN WITH TOYOTAS. THEY HAVE SAID THIS IS NOT PART OF THE POWERTRAIN WARRANTY.

2012 TOYOTA TACOMA W 47K MILES 4 YRS OLD. BOUGHT BRAND NEW FROM TOYOTA. I WAS DRIVING THE VEHICLE TO WORK AND CHECK ENGINE LIGHT AND TRAC OFF BOTH CAME ON. ATTEMPTED TO ACCELERATE UP A HILL OVER A BRIDGE AND COULD NOT GO BEYOND 20 MPH WITH ACCELERATOR ALL THE WAY DOWN!. VEHICLES SPEEDING UP ON ME, PULLED OFF INTO EMERGENCY LANE. VEHICLE TOWED AND BROUGHT TO DEALERSHIP WHERE THEY TOLD ME A 'BANK 1 SECONDARY AIR INJECTION SWITCHING VALVE' NEEDS TO BE REPLACED AT ABOUT $900. NOT COVERED UNDER WARRANTY OR A RECALL. RESEARCH ON INTERNET SHOWS THAT THIS IS A COMMON AND DANGEROUS PROBLEM FOR THIS YEAR MAKE AND MODEL. TOYOTA CC CALLED WITH REPORT FILED. SOMETHING NEEDS TO BE DONE BEFORE THERE IS A SERIOUS INJURY OR MORTALITY DUE TO THE VEHICLE NOT BEING ABLE TO ACCELERATE IN A VULNERABLE POSITION.

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.

CHECK ENGINE AND TRAC OFF INDICATOR LIGHTS CAME IN, AND VEHICLE WENT INTO FAIL CODE MODE ALSO KNOWN AS"LIMP MODE" WHILE DRIVING DOWN A TOWN ROAD. VEHICLE WAS UNABLE TO ACCELERATE ABOVE 40 MPH. MANAGED TO GET VEHICLE TO DEALERSHIP, WAS TOLD THE PROBLEM WAS A "SECONDARY AIR PUMP AND VALVE". VEHICLE HAS 56,700 MILES ON IT. TOYOTA WAS CONTACTED AND A COMPLAINT WAS FILED, BUT THEY WOULD NOT ACKNOWLEDGE A FAULT IN THE PART IN THIS MODEL VEHICLE. TOYOTA TUNDRAS HAVE HAD THE SAME ISSUE AND TOYOTA PROVIDED A FIX FOR THIS MODEL. WHEN ASKED IF THE REPLACEMENT PART WOULD FAIL IN 50,000 MILES I WAS TOLD THAT THE NEW PART WAS "UPDATED" SO IT SHOULDN'T HAVE THE SAME ISSUE. WHY DID TOYOTA ALLEGEDLY UPDATE THE REPLACEMENT PART IF THERE WAS NO FAULTS IN THE ORIGINAL PART?

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.

VEHICLE LOST POWER WHILE ON THE HIGHWAY, IMMEDIATELY REDUCED SPEED TO AROUND 40 MPH. THE "TRAC OFF" INDICATOR LIGHT CAME ON AND THE TRUCK WENT INTO "LIMP MODE", SO I WAS ABLE TO TAKE THE NEXT EXIT AND I TOOK IT TO THE AUTO PART STORE FOR A CODE READER. P2440/ P2442 CAME UP IN ERROR, SECONDARY AIR INJECTION SYSTEM STUCK OPEN. THIS WAS AN 800$ PART FROM THE DEALERSHIP AND I DID THE WORK.. TOYOTA TACOMA 4X4 2012 SR5 V6 4.0L 59,965 MILES

AT 57000 MILES CHECK ENGINE AND GETTING P2442 CODE AT START-UP. CHECKED AND IT IS A BAD SECONDARY INJECTION PUMP. CHECKED ON INTERNET AND THERE ARE MANY OTHERS WITH THE SAME PROBLEM AND TOYOTA SAYS IT'S NOT UNDER WARRANTY $1900 TO FIX

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

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.

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

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

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.

THE ENGINE LIGHT CAME ON - TOOK TO DEALER - WAS TOLD SECONDARY AIR FLOW AND PUMP NEED TO BE REPLACED.

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.

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

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

VEHICLE STUMBLED AND ENGINE ALMOST DIED WHILE MAKING A TURN IN FRONT OF INCOMING TRAFFIC WITH MY ONE YEAR OLD DAUGHTER IN THE TRUCK. MIL ON WITH CODE P2442 REPORTED, SECONDARY AIR INJECTION MALFUNCTION. THIS 2012 TACOMA IS TOYOTA CERTIFIED WITH 34,216 MILES, SPOKE WITH MULTIPLE TOYOTA REPRESENTATIVES AND ALL HAVE STATED THIS IS NOT A WARRANTIED ITEM. THIS MALFUNCTION IS COMMON ON OTHER TOYOTA TRUCKS WHICH HAVE EXTENDED WARRANTIES ON THE SAME EMISSION COMPONENT IN QUESTION. THIS PROBLEM IS BOTH A SAFETY HAZARD AND AN EMISSIONS HAZARD. IT NEEDS TO BE ADDRESSED.

SECONDARY AIR INJECTION SYSTEM TRUCK WOULD NOT ACCELERATE AND LOST POWER. I'VE NOTICED IT HAS DONE THIS SINCE NEW. I NOW HAVE 37,000 MILES ON IT AND HAVE RECEIVED MESSAGES CHECK ENGINE LIGHT AND TRAC OFF MESSAGES. THIS IS VERY DANGEROUS AS YOU HAVE NO ENGINE POWER WHEN ENTERING INTO TRAFFIC. THE TRUCK WILL NOT GO OVER 35 MILES AN HOUR AND TAKES FOR EVER TO GAIN SPEED.

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

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 WOULD OR WOULD NOT BE IN THIS MODE, OTHER THAN BY THE WAY THE VEHICLE WAS HANDLING. LIMP MODE WOULD ONLY ALLOW TRANSMISSION TO SHIFT INTO 2ND OR 3RD AND NO MORE THAN 30 MPH, LESS IF CLIMBING AN INCLINE. AT OTHER TIMES, VEHICLE WOULD DRIVE NORMALLY. THE SWITCHING IN AND OUT OF THIS PROTECTIVE MODE SEEMS PARTICULARLY DANGEROUS. *TR

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

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.

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 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 TO INCREASED POLLUTION. (HOW IS THAT NOT AN EMISSIONS RELATED PART?) THE FAILURE OR WARPING OF THE ONE-WAY CHECK VALVE CAUSES HOT EXHAUST GASES TO BACKFLOW INTO THE SOLENOID, AND MELTING THE GASKETS. THIS ENDS UP BLOCKING THE SEALING PLATE AND CAUSING IT TO REMAIN IN THE OPEN POSITION. THE DANGER IS THAT THE HOT EXHAUST IS THEN FED INTO A PLASTIC AIR PUMP CAUSING IT TO POTENTIALLY MELT OR CATCH FIRE! THE FACT THAT THIS FORCES THE VEHICLE INTO "LIMP MODE" IS ALSO A HUGE SAFETY CONCERN AS IT WILL NOT ALLOW THE VEHICLE TO TRAVEL ABOVE 35 MPH AND COULD LEAD TO SERIOUS ACCIDENTS IF TRAVELING AT HIGH SPEED ON THE INTERSTATE OR HIGHWAY DUE TO THE UNEXPECTED, SUDDEN DECELERATION. FAILED ASSEMBLY IS TOYOTA PART NUMBER : 25710-31020. THIS PART NUMBER HAS BEEN SUPERSEDED BY P/N: 25710-31022 AND TOYOTA CHARGES BETWEEN $1500-$3200 TO REPLACE. *TR

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

SECONDARY AIR INJECTION VALVE STUCK CODES P2440,P2442. TRUCK GOES INTO LIMP MODE AND YOU CAN ONLY GO A MAX OF 40 MPH.TOYOTA KNOWS ABOUT THESE ISSUES AND DOES NOTHING ABOUT IT

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

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 TO INCREASED POLLUTION. (HOW IS THAT NOT AN EMISSIONS RELATED PART?)

FAILED ASSEMBLY IS TOYOTA PART NUMBER : 25710-31020. THIS PART NUMBER HAS BEEN SUPERSEDED BY P/N: 25710-31022. *TR

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

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.

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

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

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.

WE JUST PAID TOYOTA A LITTLE OVER $2,000 TO REPLACE THE SECONDARY AIR INJECTION SYSTEM. THE SWITCHING VALVE WAS STUCK CLOSED ACCORDING TO TOYOTA. THIS IS A 4 YEAR OLD TRUCK. IT IS UNREAL TO SPEND THIS KIND OF MONEY THIS EARLY FOR THIS. THE TUNDRA HAS RECALLS FOR THIS SAME ISSUE.

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!
