Circuit Description

WARNING: This page is about a different car, the 2004 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.

The throttle actuator control (TAC) module contains data, which is essential for proper TAC system operation. The TAC module continuously checks the integrity of this data. If the TAC module is unable to write or read data to and from random access memory (RAM) or the TAC module is unable to correctly read data from the flash memory or an internal TAC module processor fault is detected, DTC P2108 sets.
