Accelerator Controls
WARNING: This page is about a different car, the 2009 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.
An electronic throttle control (ETC) system or throttle actuator control (TAC) system is used to control the throttle valve opening. The accelerator pedal receives input from the driver and the accelerator pedal position (APP) sensors send this information to the PCM. The PCM commands the desired throttle valve opening to the TAC motor on the throttle body. For additional information on the operation of this system, refer to Throttle Actuator Control (TAC) System Description .
