p0638 throttle position CEL


Recommended Posts

i had an alignment done on sunday then got the p0638 on monday. the error seams to be that the peddle sensor and throttle position sensor have a reading that is more than 0.15V off. is there a quick fix or change to the tune i can ask for? it as it seams to be reading 0.16V off when i data logged and everything else is working fine.

re update, it came back so i took it back to GST (where i just had it tuned a couple months ago,) since the car worked fin cold and hot it was determined that the coolant loop that changed the car from cold to hot was not working (there is a sensor in the throttle body that controls it.) so the cel was removed from the tune and it should just idle a bit rough when warm but not up to temp.
