REMOVAL PROCEDURE
NOTE: Handle the electronic throttle control components carefully. Use cleanliness in order to prevent damage. Do not drop the electronic throttle control components. Do not roughly handle the electronic throttle control components. Do not immerse the electronic throttle control components in cleaning solvents of any type.
1. Remove the left instrument panel (IP) lower closeout insulator panel.
2. Disconnect the APP sensor harness connector.
3. Remove the accelerator pedal mounting bolts.
4. Remove the accelerator pedal.
INSTALLATION PROCEDURE
1. Install the accelerator pedal to the steering column support bracket.
NOTE: Refer to the Fastener Notice in Service Precautions.
IMPORTANT: Always use a torque wrench in order to obtain the proper torque.
2. Install the accelerator pedal mounting bolts.
Tighten
Tighten the accelerator control assembly to floor fasteners to 20 N.m (15 lb ft).
3. Connect the APP sensor harness connector.
4. With the vehicle not in reduced engine power, turn ON the ignition, with the engine OFF. Test for proper throttle opening and closing range by operating the accelerator pedal and monitoring the throttle angles using a scan tool. The accelerator pedal should operate freely without binding between full closed throttle and wide open throttle (WOT).
5. Inspect the carpet fit under the accelerator pedal.
6. Install the left IP lower closeout insulator panel.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
