Wow! Finally a how to test video. Excellent video, did you happen to make one for TPS

[@diagnosticsdoneright]

i did not, but that test would functionally be the same just to ensure no internal shorts.

[@ronaldoguerrero-jw2on]

My Camaro has the same problem already replaced ecu throttle body and pedal any luck on urs?

[@diagnosticsdoneright]

a p2138 code on that model would indicate a short to voltage. there's likely some wires rubbed through and touching somewhere.
