Electrically driven throttle assembly: removal and installation

The electrically driven throttle assembly of the distributed fuel injection system is secured to the receiver.

It meters the amount of air entering the intake pipe.

The air supply to the engine is metered by the electrically driven throttle valve controlled by the controller.

The throttle assembly contains two throttle position sensors and an electric drive associated with them.

Removal of the throttle assembly

  1. Prepare the vehicle and disconnect the negative terminal of the battery.
  2. Remove the decorative engine cover.
