P2176 Chevrolet -

Question

originally had 4 codes: P0107, 0113, P2135 and P2176. I cleaned the MAF sensor, throttle body and all connections and cleared codes. On start up, check engine light displays "reduced engine power" and the only remaining code is P2176. What is next step?

Answer 1

P2176 first of all check in live data the throttle pedals position sensor opening angle if above 9% than minimum throttle position learning failed so before calibration clean throttle body to bring it in below 9% opening angle than it should calibrated
