Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello and welcome! My name isCustomerand I can assist you with your question. This problem is caused by a software issue with the PCM. The PCM will need to be updated or programmed to the latest calibration in order to fix this code. Once this is done, the code will no longer come up.
The best place to get the computer flashed is at the Chevy Deaership. This cost about 70 to 80 bucks.
If the vehicle is ilding high and is pulling forward more than usual, I suspect the engine has an air or a vacuum leak that needs to be addressed or the TPS is bad and will need to be replaced.
They will only do what you ask or authorize them to do. You will need to make it clear which service you would like done. But be sure to get any engine performance issue fixed first before getting the PCM updated.
Generally speaking.. no, the TPS will not cause a EGR code. However, in rare cases, it is possible if the wiring is shorted that is shared by the TPS and EGR the computer may get confused and cause this code.
