 Electronic throttle control system

The ECM cuts off throttle actuator current and the throttle valve is returned to a 7.5° throttle position by the return spring.

    - Fuel cut is performed on the malfunctioning cylinder.

  2. Under a high load and at a high engine speed:

    - Throttle valve opening angle control is performed.

    - Fuel cut is performed on all cylinders or the malfunctioning cylinder.

Tech Tips


  • *1: The vehicle can be driven slowly when the accelerator pedal is depressed firmly and slowly. If the accelerator pedal is depressed quickly, the vehicle may speed up and slow down erratically.

  • *2: Misfire-related fail-safe operations occur when catalyst overheat malfunctions occur.
