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 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.

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.

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 THESE CODES CAN CAUSE THE TACOMA TO GO INTO "LIMP MODE" WHERE YOU CAN LOOSE POWER, ACCELERATION, AND WON'T BE ABLE TO GO OVER 45MPH. I HATE TO THINK WHAT COULD HAVE HAPPENED IF I HAD KEPT MERGING ONTO THE INTERSTATE AND TRIED TO GET UP TO SPEED ONLY TO "LIMP" INTO TRAFFIC OR IF THIS HAD HAPPENED A MINUTE LATER ON THE INTERSTATE! EVERY THREAD I READ ONLINE FROM MULTIPLE SOURCES SHOW PEOPLE HAVING SIMILAR ISSUES FROM AS LOW AS 1,000 MILES ON THE TRUCK. THE ISSUES WITH THE SECONDARY AIR INJECTION PUMP AND SWITCHING VALVES SEEMS MOST COMMON BETWEEN 50,000-80,000 MILES, BUT EVENTUALLY DOES HAPPEN IN THE 2012-2015 TOCOMA MODELS.

1EA19001 · Electrical Overstress
Opened Apr 19, 2019 · Closed Sep 19, 2024
Status: closed (inferred from source dates) · Air Bags: Air Bag/restraint Control Module
The Office of Defects Investigation (ODI) opened this investigation to determine if the failure of airbags to deploy during severe crashes, in certain vehicles, was the result of a safety related defect. During the investigation a complex failure was studied that can result in non-deployment of subject vehicle air bags and other restraint system devices in severe crash events. The subject vehicles may be equipped with an airbag control unit (ACU) for the supplemental restraint system (SRS) Electronic Control Unit (ECU) manufactured by ZF-TRW. The ECU receives signals from crash sensors mounted in the vehicle and deploys the vehicle air bags and seat belt pretensioners in accordance with manufacturer design specifications. The ECU in the subject vehicles contains a model DS84 application-specific integrated circuit (ASIC) which controls the communication of the crash sensor signal, firing commands (i.e., when to deploy the airbag(s) and/or pretensioners), and fault information (e.g., diagnostic trouble codes). In September 2016, FCA announced recall 16V-668 for certain model year (MY) 2010 to 2014 Chrysler, Dodge and Jeep products manufactured with the subject ZF-TRW ACU. In this recall, FCA discussed an EOS condition that resulted in a failure of the subject DS84 ASIC, which caused air bag non-deployment. FCA noted that the defect condition had only been observed in vehicles equipped with sensor harnessing routed across the front of the vehicle. Other FCA vehicles that also used the subject ACU, but were not equipped with cross-car harnessing, had not experienced EOS failures, despite similar time in service. During the course of this investigation, ODI sent two separate Information Request (IR) letters to six vehicle manufactures (including FCA, Hyundai, Honda, Kia, Mitsubishi, and Toyota) and one IR letter to ZF-TRW. These IR letters resulted in ODI receiving comprehensive data from these manufacturers and suppliers. Studies of this data found that the DS84 ASIC does not have sufficient protection against negative electrical transients or electrical overstress (“EOS”) that can be generated in certain severe crashes. An electrical transient occurs when the electrical power supplied to a circuit changes momentarily over a short duration of time. In these severe crash cases, the crash sensors and other powered wiring can be damaged and short circuited so as to create a negative electrical transient of sufficient intensity and duration (that are outside the vehicle manufacturer's specification) to damage the ASIC before the restraint device deployment signal is received by the SRS ECU. This damaged signal can lead to incomplete or nondeployment of the air bags and/or pretensioners. Airbag non-deployment and/or lack of pretensioner operation can increase the risk or severity of injury in a crash.A total of 8 fatalities and 14 injuries were associated with known EOS events. The common element in all investigated manufacturers vehicles is the SRS ECU containing a DS84 ASIC manufactured by ZF-TRW. The risk associated with the ASIC is equally shared among all OEMS involved in the investigation. The actual real-world risk can be mitigated by other factors which were assessed by ODI during this investigation. The first mitigating factor involves protections built into the ACU design which protect the DS84 ASIC from damage. There are multiple strategies and levels of protection employed by different OEMs that provide effective EOS mitigation. The two most common strategies at the ACU level are circuit protection diodes on the remote senor signal lines, and current limiting resistors that protect critical components. The second mitigating factor is found at the vehicle level and involves the location and routing of the wires leading from the crash sensors to the SRS ECU. If the wires are well protected in a crash and are not routed with other power wires carrying large currents, the risk for an EOS event is significantly reduced or eliminated. These design specific factors combine to produce a spectrum of risk for the vehicles equipped with ACUs using the DS84 ASIC. Given the many of years of field exposure, it is possible to divide the subject population into two groups; vehicles which have experienced EOS events, and vehicles which have not experienced EOS field events. Four of the six OEMs involved in this investigation have experienced EOS field events on at least one of their models equipped with a DS84 ASIC. All vehicle models (including the Toyota models identified in the Failure Report Summary of the opening resume for this investigation) with field events have been recalled. In an abundance of caution, ODI kept this investigation open five years to monitor field performance and did not identify any field events on vehicles not included in existing safety recalls. Given the spectrum of risk identified in this investigation and that all vehicles with a demonstrated unreasonable risk have been recalled, ODI is closing this investigation. ODI is closing this investigation with the following manufacturer safety recalls: 16V-668, 18E-043, 18V-137, 18V-363, and 20V-024. With the recall actions taken by the subject vehicle and equipment manufacturers, this investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exists on other model or model year vehicles outside of the recall scopes. The agency reserves the right to take further action if warranted by the circumstances.
