2012 TOYOTA TACOMA Complaints

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.

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 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??

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

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.

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.
