Description & Operation: Description

• 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 signal 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.
