Circuit Description
WARNING: This page is about a different car, the 1998 Buick Riviera. However, it is still accessible from the selected car via links, so may be relevant.
Throttle Position (TP) sensor measures amount of throttle opening. PCM uses TP sensor information for fuel delivery calculations. TP sensor readings during acceleration are much higher than those during deceleration or idle.
Conditions required to set DTC are:
- Engine running and throttle steady.
- No MAP or TP sensor DTCs are set
- Throttle angle steady.
- Predicted throttle angle not close to actual throttle angle.
- Conditions present for at least 10 seconds.
