Solution

1. Preparation

Gather Tools and Parts: Ensure you have an OBD-II scanner, multimeter, socket set, throttle body cleaner, and a set of basic hand tools.
Safety Precautions: Disconnect the negative battery terminal to prevent any electrical shorts.

2. Clean the Throttle Body

Remove the air intake duct to access the throttle body.
- Tools: Socket set
Use throttle body cleaner to spray inside the throttle body.
- Ensure the throttle plate is fully open during cleaning.
Wipe the inside with a clean cloth to remove any carbon deposits.
Reattach the air intake duct securely.

3. Inspect and Replace Accelerator Pedal Position Sensor

Locate the accelerator pedal position sensor, typically found near the accelerator pedal assembly.
Disconnect the electrical connector from the sensor.
Remove the sensor using the appropriate socket.
Install the new sensor by reversing the removal steps.
