Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Ensure the vehicle is on a flat surface and in park mode.

2. Inspect and Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use a throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
Reassemble the air intake duct securely.

3. Replace Accelerator Pedal Position Sensor (if faulty)

Locate the accelerator pedal assembly under the dashboard.
Disconnect the electrical connector from the sensor.
Remove the mounting screws and detach the old pedal position sensor.
Install the new sensor in the reverse order, ensuring it is aligned correctly.
Reconnect the electrical connector securely.

4. Inspect and Repair Wiring Harness

Visually inspect the wiring harness connected to the throttle body and accelerator pedal.
Repair any damaged or corroded wires with heat-shrink tubing or electrical tape.
Ensure all connections are secure and free from moisture.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and allow it to idle.
Gradually press the gas pedal to check for throttle response.
