Circuit Description

The throttle actuator control (TAC) module contains data, which is essential for proper TAC system operation. The TAC module continuously tests the integrity of this data. If the TAC module detects a fault with electrically erasable programmable read only memory (EEPROM), 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 the TAC module does not agree with the vehicle ID from the PCM, DTC P2107 sets.
