P2135 Chevrolet - aveo

Question

A7E code or p 2135 .engine light is coming on and off all the time more it's in the morning

Answer 1

Hi there,

This code is for the throttle position sensor. If it's more common in the morning then I would assume you have a connection issue. You may be able to disconnect the TPS and reconnect it to give it a better or cleaner connection. The TPS is part of the electronic throttle body and itn's servicable without replacing the throttle body.

GM also has a TSB for this code, so it might be wise to give them a call.
