2012 TOYOTA TACOMA Engine Problems

June 1st 2021 I went to park in a parking space at a local mall. My truck instead of stopping it accelerated out of control jumped two stone curbs, drove though a fence and landed into a swamp. Call Toyota and they have opened a new case # 210602000065. Police report # 21-374-AC. This isn't the first time that this has happen with this truck. It happen in Aug 2019. I contacted Toyota case number 1908060035. They sent out EAA Engineering Analysis Ass. out who did a ACM.CDRX file a month later. Toyota came back said they couldn't find anything wrong and my case was closed. Another incident in winter of 2016 where my truck was stopped and it accelerated on its own and It drove in the 4 way intersection where it caused an accident. lots of damage to cars. Toyota was contacted and they sent me to a...

I BROUGHT TRUCK TO TOYOTA DEALERSHIP AS PART OF RUSTED FRAME RECALL TO BE VERIFIED. THEY STATED TRUCK WAS NOT RUSTED ENOUGH UNDERNEATH FOR TOYOTA TO APPROVE RECALL. THAT WAS A COUPLE OF MONTHS AGO. I HAVE RECENTLY BROUGHT IT TO A FEW MECHANICS TO DO SOME WORK ON A/C AS THE A/C STOPPED WORKING AND THAT REFUSE TO WORK ON IT AS THE TRUCK IS SO RUSTED UNDERNEATH!! THEY SAID IT WOULD CRUMBLE. NOT EVEN WORTH IT.

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...

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...

I WAS ON THE THE HIGHWAY TODAY AND SUDDENLY I LOST POWER AND WON'T PASS SPEEDS OVER 40 MPH VERY DANGEROUS HAVE HEARD THIS HAPPEND TO A LOT OF TACOMAS/ TUNDRAS AND HAS TO DO SOMETHING WITH THE EMISSIONS I THINK I NEED A NEW DIVERTER VALVE WHICH TOYOTA SHOULD COVER

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

DURING NORMAL DRIVING, THE CHECK ENGINE LIGHT AND TRACTION CONTROL OFF LIGHT CAME ON AND TRUCK IMMEDIATELY WENT IN TO LIMP-HOME MODE. I HAD IT SCANNED FOR CODES AT THE LOCAL AUTO PARTS STORE AND IT CAME BACK WITH P2440 AND P2442 WHICH SEEMS LIKE A COMMON ISSUE WITH A VALVE IN THE SECONDARY AIR INJECTION SYSTEM. I QUICK GOOGLE SEARCH SHOWED THAT SOME 2012 TACOMA OWNERS ARE GETTING THIS COVERED UNDER A SPECIAL WARRANTY EXTENSION, SO I PUTTERED OVER TO THE TOYOTA DEALERSHIP EXPECTING TO HEAR THE SAME STORY, BUT THEY ARE TELLING ME THE ECM COMPUTER IS BAD. WHICH I AM TRYING TO GET CLARIFICATION ON SINCE I CAN'T FIND ANY ECM FAILURE ISSUES FOR THIS MAKE AND MODEL YEAR.

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

THE SECONDARY AIR INJECTION SYSTEM WENT OUT

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.

TL* THE CONTACT OWNS A 2012 TOYOTA TACOMA. WHILE DRIVING VARIOUS SPEEDS AND DEPRESSING THE ACCELERATOR PEDAL, THE VEHICLE FAILED TO ACCELERATE. ALSO, THE TRACTION CONTROL AND CHECK ENGINE WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE SECONDARY AIR INJECTION VALVE FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE VEHICLE WAS NOT TAKEN TO A DEALER. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 45,000.

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

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.

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.

THE CHECK ENGINE LIGHT AND THE TRAC OFF LIGHT CAME ON AS I WAS MERGING ONTO THE INTERSTATE. I IMMEDIATELY STOPPED THE VEHICLE, PULLED OVER, AND TOOK MY 2012 TOYOTA TACOMA WITH 78,000 MILES TO THE MECHANIC WHERE I LEFT IT OVERNIGHT FOR THEM TO LOOK AT IT IN THE MORNING. RUNNING A DIAGNOSTIC THEY FOUND CODE P2443 - SECONDARY AIR INJECTION SWITCHING VALVE STUCK. I ASKED IF THEY HAD DEALT WITH THIS BEFORE AND THEY SAID THIS IS A COMMON PROBLEM FOR TOYOTA AND THEY HAVE DONE RECALLS ON BOTH THE TUNDRA AND SEQUOIA MODELS THAT HAVE HAD THESE ISSUES, BUT THE TACOMA HASN'T HAD A RECALL YET, EVEN THOUGH IT SEEMS TO BE JUST AS COMMON WITH THE SAME PARTS. THEY SAID THE COST OF PARTS AND LABOR WOULD BE AROUND $2,000. WHEN I ASKED THEM IF THE VEHICLE WAS SAFE TO DRIVE OFF THEIR LOT THEY SAID...

AT LESS THEN 50K MILES ON THE ODOMETER AND 900 MILES FROM HOME MY TRUCK DECIDED TO GET A CHECK ENGINE LIGHT AND TRAC OFF LIGHT CAUSED BY CODES P2440 AND P2442 AND P2445. MERRY CHRISTMAS TO ME. THESE CODES PUT ME INTO LIMP MODE WHILE ON THE FREEWAY IN SNOWY AND ICY CONDITIONS. I COULD NOT MAINTAIN SPEED WITH THE FLOW OF TRAFFIC AS I WAS TRYING TO GET TO THE SHOULDER WITH TRAFFIC ZOOMING ALL AROUND ME, DANGEROUS AND SCARY! TOYOTA WANTS $2000 TO REPAIR IT. INTERNET RESEARCH HAS SHOWN ME THAT IT IS A COMMON PROBLEM THAT TOYOTA FAILS TO RECOGNIZE FOR TACOMAS BUT HAS ISSUED A TSB AND EXTENDED WARRANTIES FOR TUNDRAS. SHAME ON TOYOTA. NOW I GET TO ENDURE THE COST OF REPAIR AFTER THE HOLIDAY SEASONS AND I'M SURE MY BOSS WILL LOVE TO HEAR I WONT BE RETURNING TO WORK ON TIME.

ALMOST LOST CONTROL OF VEHICLE WHEN THE TRUCKS PERFORMANCE JUMPED INTO LIMP MODE "TRAC OFF" AS I WAS DRIVING. LOSS OF SPEED AND PERFORMANCE CAUSED ME TO BE A DRIVING HAZARD. 2 VENDORS TODAY FOUND THE CODES P2440 AND P2442, WHICH APPEAR TO HAVE TRIGGERED MY TRUCK INTO "TRAC OFF" AND "CHECK ENGINE" LIGHT ON. MODE CAUSES MY TRUCK TO ONLY DRIVE ABOUT 45 SIGNIFICANTLY IMPACTS PERFORMANCE AND DANGEROUS TO DRIVE. THIS IS A SAFETY HAZARD,I HAD NO WARNING THAT THE LOSS OF PERFORMANCE WAS GOING TO HAPPEN INITIALLY WHEN I WAS TRAVELING.THERE IS ANOTHER PROBLEM THAT APPEARS TO BE ON A LARGER SCALE.I HAVE BRIEFLY SCANNED THE INTERNET IN THE LAST HOUR AND SPOKE WITH VARIOUS VENDORS ABOUT THE PROBLEM & I HAVE CALLED MY DEALERSHIP & EVEN THE MAIN TOYOTA LINE AND EVERYONE IS AWARE OF THE ISSUE. THE CODES ARE P2440 & P2442. AFTER FINDING OUT THE...

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...

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...

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...

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.

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

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.

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...

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.
