Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical issues.
Ensure the vehicle is on a flat surface and secure with wheel chocks.

2. Inspect and Clean the Accelerator Pedal Assembly

Remove the cover from the accelerator pedal assembly, if applicable.
Clean any debris or contaminants around the pedal mechanism using a soft cloth and a suitable cleaner.
Check for any loose connections and tighten them as necessary.

3. Check and Adjust the Throttle Cable (if applicable)

Inspect the throttle cable for kinks or frays. If damaged, replace the cable.
Adjust the throttle cable tension as per manufacturer specifications.
Ensure the cable moves freely without binding.

4. Replace the Throttle Position Sensor (if necessary)

If the TPS is malfunctioning, disconnect it from the wiring harness.
Remove the screws or bolts securing the TPS to the throttle body.
Install the new TPS in the same position as the old one and secure it with screws or bolts.
Reconnect the wiring harness to the new TPS.

5. Reassemble and Test

Reinstall any covers that were removed during the process.
Reconnect the negative battery terminal.
Start the vehicle and check for proper operation of the accelerator pedal and throttle response.
