Electronic Throttle Actuator: Testing and Inspection

ETC (ELECTRONIC THROTTLE CONTROL) SYSTEM

INSPECTION

FUNCTION AND OPERATION PRINCIPLE

The Electronic Throttle Control (ETC) System consists of a throttle body with an integrated control motor and throttle position sensor (TPS). Instead of
the traditional throttle cable, an Accelerator Position Sensor (APS) is used to receive driver input. The ECM uses the APS signal to calculate the target
throttle angle; the position of the throttle is then adjusted via ECM control of the ETC motor. The TPS sign& is used to provide feedback regarding
throttle position to the ECM. Using ETC, precise control over throttle position is possible; the need for external cruise control modules/cables is
eliminated.
