Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery cable to prevent electrical shock.

2. Inspect and Clean Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner into the throttle body and use a soft cloth to remove carbon deposits.
Reattach the air intake duct and ensure it is securely fastened.

3. Replace Accelerator Pedal Position Sensor (if faulty)

Locate the accelerator pedal position sensor attached to the accelerator pedal assembly.
Disconnect the wiring harness from the sensor.
Remove the screws or bolts securing the sensor to the assembly.
Install the new sensor, ensuring it is aligned properly, and reattach the wiring harness.

4. Check and Repair Wiring

Inspect the wiring harness for any frays or damage.
Use a multimeter to check for continuity in the wires leading to the throttle body and accelerator pedal sensor.
Repair or replace any damaged wiring as necessary.

5. Reconnect Battery and Test

Reconnect the negative battery cable.
Start the engine and allow it to idle for a few minutes.
Test the throttle response by pressing the accelerator pedal gently.
