Accelerator Pedal Sender

Print

The accelerator pedal sender is used on EML equipped vehicles. This is the sensor that tells the EML unit how far the accelerator pedal has been depressed. This takes the place of the throttle cable.

Anytime the accelerator pedal sender is adjusted or replaced, the external safety path check must be made. Be sure to have the tester tool 12 7 010 or equivalent, is available for use before starting these procedures.

REMOVAL & INSTALLATION



  1. Turn the ignition switch OFF .
  2.  
  3. Remove the lower dash trim from around the accelerator pedal location.
  4.  
  5. Unscrew the nut from the sender shaft and pull off the pedal lever.
  6.  
  7. Remove the 2 bolts from the sender and disconnect the electrical connector. Note the positions of the spacers, if equipped, for installation.
  8.  
  9. Rotate the sender until the eye can pass through the opening, then rotate until the other mounting eye can pass through the opening. Tilt the sender so the clips can pass through the opening. Turn the sender so the eyes align with the mounting holes and remove completely.
