Removal Procedure


Object Number: 42165  Size: SH
  1. Remove the left instrument panel sound insulator. Refer to Instrument Panel, Gages and Console.
  2. Remove the accelerator cable from the accelerator pedal.
  3. Squeeze the accelerator cable cover tangs and push the accelerator cable through the bulkhead.
  4. Remove the cover from throttle modulator.
  5. Remove the accelerator cable from the throttle modulator.

Installation Procedure

Notice: Do not route flexible components (hoses, wires, conduits, etc.) within 50 mm (2 in) of moving parts unless flexible components can be securely fastened. This is necessary in order to prevent possible interference and damage to the component.


Object Number: 42165  Size: SH
  1. Install the accelerator cable through the bulkhead.
  2. Install the snap retainer through the bulkhead.
  3. Install the accelerator cable through the slot in the accelerator pedal lever.
  4. Seat the snap retainer in the accelerator pedal lever.
  5. Install the accelerator cable to the throttle modulator upper cam.
  6. Perform adjustment procedure as outline in this section.
  7. Install the modulator cover.
  8. Install the lower instrument panel trim.
  9. Apply heavy bodied sealer around accelerator cable at engine compartment side of bulkhead.
  10. Check for complete throttle opening and closing positions by operating the accelerator pedal. Also check for poor carpet fit under the accelerator pedal.
  11. The throttle should operate freely, without binding, between full closed and wide open throttle.

Accelerator Controls Pedal

Removal Procedure


Object Number: 12287  Size: SH
  1. Remove the left instrument panel sound insulator. Refer to Instrument Panel, Gages and Console.
  2. Remove the accelerator cable from accelerator pedal.
  3. Remove the accelerator pedal fasteners and accelerator pedal.

Installation Procedure


Object Number: 12287  Size: SH
  1. Install the accelerator pedal with attaching fasteners.
  2. Install the accelerator cable to the accelerator pedal
  3. Install the left instrument panel sound insulator. Refer to Instrument Panel, Gages and Console.
  4. Check for complete throttle opening and closing positions by operating the accelerator pedal. Also check for poor carpet fit under the accelerator pedal.
  5. The throttle should operate freely without binding between full closed and wide open throttle.

Accelerator Controls Modulator

Removal Procedure


Object Number: 42185  Size: SH
  1. Remove the throttle modulator cover.
  2. Remove the accelerator cables from throttle modulator cams.
  3. Remove the bolts attaching throttle modulator to throttle modulator bracket.
  4. Remove the throttle modulator.

Installation Procedure


    Object Number: 42185  Size: SH
  1. Install the throttle modulator over stud on throttle modulator bracket.
  2. Install the throttle modulator attaching bolts.
  3. Tighten
    Tighten the throttle modulator attaching bolts to 3.5 N·m (31 lb in).

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  4. Install the accelerator cables to throttle modulator cams.
  5. Perform adjustment procedure as outlined in this section.
  6. Install the throttle modulator cover.

Accelerator Controls Accelerator Cable Adjustment

Adjustment Procedure


Object Number: 42187  Size: SH
  1. The cruise control cable must be adjusted prior to performing this procedure.
  2. The accelerator control cable adjustment procedure must be followed each time the accelerator cable is disconnected from the throttle body and when any components in the remote progressive throttle system are replaced.
  3. Lift the adjustment lever on the accelerator cable up to the unlocked position.
  4. Hold the throttle in the closed position while pulling the cable conduit towards the throttle body to adjust the slack.
  5. Push the adjustment lever down to the locked position.
  6. Check for complete throttle opening and closing positions by operating accelerator pedal. Also check for proper carpet fit under the accelerator pedal. The throttle should operate freely without bind between full closed and wide open throttle.
  7. Using the Scan Tool, check throttle angle percentage by depressing the accelerator pedal. When the accelerator pedal is released, throttle opening should return to 0%. If proper results are not obtained, check modulator and cables for damage or kinks and repeat procedure.

Accelerator Controls Cruise Cable Adjustment

Adjustment Procedure

  1. Unlock cable conduit at accelerator cable bracket.
  2. With the throttle closed, lock the cable conduit by pressing down on the cable lock.
  3. When the cable is in the unlocked position, and the throttle is closed, the cable adjustment spring removes the appropriate amount of slack.
  4. Cable lock must be fully extended to allow proper adjustment spring operation prior to locking.
