Electronic Throttle Actuator: Description and Operation
ENGINE CONTROL COMPONENTS
Throttle Actuator Control (TAC) Motor
The TAC motor is a DC motor controlled by the PCM (requires two wires). The motor housing is integrated into the main housing. An internal spring
is used to return the throttle plate to a default position. The default position is typically a throttle angle of 7 to 8 degrees from the hard stop angle. The
closed throttle plate hard stop is used to prevent the throttle from binding in the bore. This hard stop setting is not adjustable and is set to result in less
airflow than the minimum engine airflow required at idle. For additional information, refer to the Torque Based Electronic Throttle Control (ETC).
