Print

Operation



The driver supplies the torque requirements for the engine by operating the accelerator pedal in accordance with the desired speed or acceleration. The pedal sensor converts the mechanical operation of the pedal into an electrical signal and sends the information to the PCM. The PCM adjusts the quantity of the fuel that is injected into the engine.

Removal & Installation



  1. Before servicing the vehicle, refer to the Precautions section
  2.  
  3. Disconnect negative battery cable.
  4.  
  5. Disconnect electrical connectors, if equipped with adjustable pedals remove the adjuster cable at accelerator adjuster motor.
