Circuit Description

WARNING: This page is about a different car, the 1996 Oldsmobile Ninety-Eight and 1996 Buick Park Avenue. 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.
