Question

I got the code P2135 on my 2003 Chevrolet 8.1L V8 what is the most common cause and common fix

Answer 1

The most common cause is a dirty throttle body, the most common fix is taking it apart and cleaning it up. Basically there are two TPS sensor circuits. If one of them disagrees with the other it will store this code.

Answer 2
