Solution

1. Preparation

• Remove the air intake duct to access the throttle body.
• Disconnect the electrical connector from the throttle body.
• Remove the throttle body mounting bolts and carefully detach it from the intake manifold.
• Clean the throttle body using throttle body cleaner and a soft brush to remove any carbon deposits.

• Reinstall the throttle body, ensuring a proper seal with new gaskets if required.

3. Replace Throttle Position Sensor (if needed)

• Tools Required: Socket set, multimeter.
• Locate the throttle position sensor on the throttle body.
• Disconnect the electrical connector from the sensor.
• Remove the sensor mounting screws and take out the old sensor.
• Install the new throttle position sensor, ensuring it is oriented correctly.
• Reconnect the electrical connector.
