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 terminal to prevent electrical shock.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft cloth, socket set.
Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner onto a soft cloth and clean the inside of the throttle body, removing any carbon build-up.
Allow it to dry before reassembling.

3. Replace Throttle Position Sensor (if necessary)

Tools Required: Socket set, screwdriver, torque wrench.
Disconnect the electrical connector from the TPS.
Remove the mounting screws using a socket set and carefully take out the TPS.
Install the new TPS, ensuring it is aligned properly.
Torque the TPS mounting screws to the manufacturer’s specifications (consult the service manual).
Reconnect the electrical connector.
