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 detects a fault with EEPROM or the TAC module detects a low voltage while the voltage on the powertrain control module (PCM) is not low or the TAC module detects the vehicle ID from TAC module does not agree with the vehicle ID from the PCM, DTC P2107 sets.
