The Electric Throttle Control (ETC) Actuator consists of the Throttle Control Motor, Accelerator Pedal Position (APP) Sensor, Throttle Position Sensor (TPS), etc. The actuator sends a signal to the Engine Control Module (ECM), and ECM sends signals to Transmission Control Module (TCM) with Controller Area Network (CAN) communication.
