Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: Socket set, screwdriver set, multimeter, cleaning supplies (brake cleaner, rags), lubricant (silicone spray or white lithium grease).
Safety Warnings: Ensure the vehicle is in park and the ignition is off to prevent accidental acceleration.

2. Inspect Gas Pedal Assembly

Remove any floor mats or obstructions that may interfere with the gas pedal movement.
Visually inspect the gas pedal for any physical damage or binding points.
If necessary, remove the gas pedal assembly by unscrewing the mounting bolts.

3. Clean and Lubricate

Use brake cleaner and a rag to clean the pivot points of the gas pedal and the area around it.
Apply a light coat of silicone spray or white lithium grease to the pivot point to ensure smooth movement.
If the throttle cable is present and appears binding, lubricate it accordingly or replace if damaged.

4. Inspect Throttle Position Sensor (TPS)

Disconnect the TPS connector.
Use a multimeter to check the voltage output while slowly pressing the gas pedal. The voltage should change smoothly without spikes.
If the TPS is faulty, replace it with a new unit.

5. Reassemble and Test

Reattach the gas pedal assembly and ensure all bolts are torqued to manufacturer specifications.
Reconnect the TPS and all other connectors removed during the inspection.
Test the gas pedal by pressing it multiple times to ensure smooth operation and that it returns properly.
