Solution

1. Preparation

Gather necessary tools and parts.
Tools Required: Socket set, screwdrivers, OBD-II scanner, multimeter.
Parts Required: Throttle position sensor (if defective), throttle body cleaning spray.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Inspect Gas Pedal Assembly

Remove the lower dash panel covering the pedal area using a screwdriver.
Check for any debris or foreign objects stuck around the pedal assembly.
If necessary, clean the area with a soft cloth.

3. Check Throttle Cable or Electronic Control

If the vehicle has a throttle cable, inspect it for fraying or kinks. Replace if damaged.
For electronic throttle control, disconnect the battery before removing the throttle body connector.
Inspect the connector for corrosion or loose connections. Clean and reconnect if necessary.

4. Clean the Throttle Body

Remove the throttle body from the intake manifold (if applicable).
Use throttle body cleaning spray to clean any carbon deposits on the throttle plate and housing.
Reinstall the throttle body and torque bolts to the manufacturer’s specification.

5. Reassemble and Test

Reattach any panels or covers that were removed.
Reconnect the battery and clear any diagnostic codes using the OBD-II scanner.
Start the engine and test the gas pedal for proper function. Ensure it returns to idle position smoothly.
