Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is turned off.

2. Inspect and Clean the Accelerator Pedal Assembly

Remove any floor mats that may obstruct the pedal.
Visually inspect the accelerator pedal for debris or damage.
Clean the pedal assembly with a suitable cleaner to remove any dirt or grime.

3. Check the Throttle Cable

If applicable, inspect the throttle cable for signs of wear or binding.
Disconnect the throttle cable from the pedal and check for smooth movement by hand.
If the cable is damaged, replace it with a new one.

4. Examine the Pedal Position Sensor

Locate the pedal position sensor mounted on the accelerator pedal assembly.
Disconnect the electrical connector and use a multimeter to test for proper voltage output.
If the sensor is faulty, replace it with a new one, ensuring correct calibration.

5. Lubricate Linkages and Pivot Points

Locate all linkage components connected to the accelerator pedal.
Apply a suitable lubricant to all pivot points and moving parts to ensure free movement.
Operate the pedal several times to distribute the lubricant evenly.
