Powertrain Control Module

WARNING: This page is about a different car, the 2005 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.

The powertrain control module (PCM) determines the drivers intent and then calculates the appropriate throttle response. The accelerator pedal position (APP) sensor 1 enables the PCM to provide a target value to the TAC module in response to accelerator pedal movement. The throttle position (TP) sensor 1 input enables the PCM to determine whether the throttle valve opening is correct for the desired engine operation at that moment.
