Solution

1. Preparation

Gather tools: socket set, screwdrivers, multimeter, cleaning supplies (throttle body cleaner), and safety gloves.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner to gently clean the throttle plate and surrounding area.
Inspect the throttle body for any mechanical binding; ensure it opens and closes smoothly.
Reinstall the air intake duct securely.

3. Check and Adjust Throttle Cable (if applicable)

Locate the throttle cable at the pedal assembly and throttle body.
Check for proper tension and ensure there are no kinks or frays in the cable.
Adjust or replace the throttle cable if necessary, ensuring it has adequate slack for full pedal movement.

4. Replace Throttle Position Sensor (if faulty)

Disconnect the wiring harness from the throttle position sensor.
Remove the old sensor using a socket set.
Install the new throttle position sensor, ensuring it is correctly aligned.
Reconnect the wiring harness securely.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and check for normal pedal operation.
Conduct a test drive to ensure the gas pedal returns to the resting position and the vehicle accelerates smoothly.
