Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, cleaning cloth
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Throttle Body Cleaning (if necessary)

Remove the air intake duct connected to the throttle body by loosening the clamps.
Use a throttle body cleaner and a clean cloth to wipe the throttle body and remove any carbon deposits.
Ensure the throttle plate moves freely and is not sticking.

3. Reconnect Throttle Body

Reattach the air intake duct, ensuring all clamps are secured.
Reconnect the negative battery terminal and ensure it is tightened.

4. Throttle Body Reset Procedure

Insert the key into the ignition and turn it to the "ON" position without starting the engine.
Wait for about 10 seconds to allow the throttle body to reset its position.
Start the engine and let it idle for about 10 minutes without any load.
During this time, avoid pressing the accelerator pedal to allow the throttle body to calibrate.

5. Final Steps

After the idle period, turn off the engine and then restart it to ensure proper operation.
Perform a test drive to confirm that the throttle response is normal.
