P0120 Pontiac -

Question

Hi, I have the Throttle Position Sensor but can not find where it goes? Also my 2 codes are P0120 and P1516. How do I know which sensor to replace, the throttle position or the pedal sensor? I have a 2004 Pontiac Grand Prix GT. Thanks

Answer 1

P0120 Throttle Position sensor  /  switch "A" circuit malfunction

P1516 Reduced engine power

If the TPS sensor  set P1516 also set this is the TPS that is on the throttle bodywhich will require a replacement of the Throttle body.. At one time the ETC pedal was under a recall Recall TSB  # 05018.
