Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
This code leads to either a short in the wiring to the throttle actuator,the throttle body itself (in this case yours has been replaced already) or the PCM (engine and transmission computer at fault).
In most cases when the throttle body is replaced and the issue has not been corrected it is either a fault with a loose connection at the throttle body with bent open pins in the connector needing re bent or replaced or a wiring fault leading from the PCM to the throttle body.This needs inspected closely.
If you would like I can post the entire diagnostic procedure on this as well as the wiring diagram for the throttle actuator control just let me know if this is something you would like me to do.
