2015 Toyota Tacoma: check engine light

Filed Apr 9, 2023 · Electrical, Engine · FL

TRAC OFF & ENGINE lights came on. Removed gas cap and put it back on. Removed cables to the battery and left them off. Replaced battery cables. Lights remain on. Went to dealership and they charged $100 to scan vehicle. They don't know what's wrong and said it'd be another $800 to check further. They said maybe a rodent had chewed through a cable??? Have seen several reports of this vehicle condition and the battery cable resetting took care of the problem a lot of the time. Not this time. Don't feel comfortable A. driving the truck with these lights on and B. Don't feel comfortable with handing over $800 for them to look into it. What to do?????????????

When starting vehicle (2015 Tacoma TRD Sport) on a cold morning, received check engine light and trac light. Used code reader and received code P0418 Secondary Air Injection System Control A Circuit error. I reset the code and it came back immediately. I did some research and it is a known issue. I also contacted a local Toyota Dealer (Kool Toyota) and they stated there is no open recalls on my vehicle and that they have replaced this on some vehicles but mine is not included on the recall. In review this is a known issue with the Secondary Air Injection System failing with Tacomas yet Toyota fails to do anything about it. It is an expensive fix for a known issue. Toyota has recalled 2012s and have a service notice for a fix but it is expensive. The Service notice was created because of the issue however they fail to do anything about it besides a service notice.

The engine light and the track off warning light came on at the same time as i started the engine when i got off work. on the way home i noticed acceleration was not happening as it should when i pressed the gas pedal. I had a mechanic code it and he said it was the switching valve and the air injection pump which would cost about 1200 dollars to fix. My 2015 Toyota Tacoma only have 35000 miles on it. After during so research i found that this is a problem with other toyota truck owners. This could be a safety problem while driving in a situation where you would need to accelerate in fast moving traffic and maintain speed without slowing the traffic behind you

Secondary air injection system (sais) - one way flapper below injector valve sticks either open/closed, throws off whole sais and sets car in limp mode with corresponding check engine light code.

I was driving straight away going up a slight hill on the hwy excelling and pressing the gas pedal when the power suddenly dropped and went down to 20 MPH while I pressed the gas pedal even more the engine sounded like it was revving but the speed stayed at 20 MPH or less.- the check engine light, vsc & trac lights all came on. I immediately pulled over and decided to turn around and not continue up the hill. While driving on the straight away (still on the hwy) the vehicle's speed improved a little but only in spurts- going upwards to 40 MPH then falling again to 20 MPH at least 3 times in the 20 minute drive home. The vehicle sounded and felt like it was straining for power. All of the fluids, oils etc.. Was filled and in good standings- this vehicle is only 6 months old and has 4434 miles on it. I took the vehicle to the toyota dealer the very next day and they found that this was a manufacturing problem. The codes p2445 and p2441 was found faulty and was replaced- in the report it was stated that the car is down, considered unsafe to drive because the vehicle may go into limp mode for this condition while driving. I am submitting a portion of the report with my personal information covered.
