Electronic Throttle Control System (ETCS) |
ECM cuts off throttle actuator current and throttle valve returns to 6° throttle position by return spring. ECM then adjusts engine output by controlling fuel injection (intermittent fuel-cut) and ignition timing in accordance with accelerator pedal opening angle to allow vehicle to continue at minimal speed. |

Accelerator Pedal Position (APP) Sensor |
APP sensor has 2 sensor circuits: Main and Sub. If either of the circuits malfunctions, ECM controls engine using the other circuit. If both of the circuits malfunction, ECM regards accelerator pedal as being released. As a result, throttle valve is closed and engine idles. |
