Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool before starting work to avoid burns.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Use throttle body cleaner and a soft cloth to clean the interior of the throttle body, ensuring that the throttle plate can move freely.
Reattach the air intake duct securely.

3. Inspect and Replace the Throttle Position Sensor (if necessary)

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector from the sensor.
Remove the screws securing the sensor using a Torx bit.
Install the new throttle position sensor in reverse order and reconnect the electrical connector.

4. Inspect and Replace the Throttle Cable (if applicable)

If the throttle cable is frayed or binding, remove it from the throttle body and accelerator pedal.
Install the new throttle cable, ensuring it is properly routed and adjusted for smooth operation.
