Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello, my name is***** throttle position sensor is built into the throttle body assembly. This is about a $400 job to have repaired at a shop otherwise you can buy throttle body off ebay and install yourself for cheapest option. Let me know if you have more questions or if you would like replacement instructions. Thanks!
Yes, you need the throttle body assembly and not the accelerator position sensor. If accelerator position sensor was problem you wouldn't be getting this code. This code set when ECM detected the throttle position indicated by TP sensor 1 exceeded the throttle position indicated by TP sensor 2 by more than a predetermined value. The Throttle Actuator Control (TAC) system monitors the throttle position with a pair of sensors. Let me know if you have more questions, thanks.
