Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface, and the engine is off and cool.
Disconnect the battery to prevent electrical shorts.

2. Remove Throttle Body

Tools Required: Socket set, torque wrench, screwdriver set
Remove the air intake duct connected to the throttle body by loosening the clamps and detaching it.
Disconnect the electrical connectors from the throttle body.
Unscrew the throttle body mounting bolts using the socket set, and carefully remove the throttle body from the intake manifold.

3. Clean Throttle Body

Inspect the throttle body for carbon buildup or debris.
Tools Required: Throttle body cleaner, soft cloth, and a brush
Spray throttle body cleaner inside and around the throttle plate, and scrub gently with a soft cloth or brush to remove any buildup.
Ensure the throttle plate can move freely without obstruction.

4. Inspect and Replace Throttle Position Sensor (if necessary)

If testing indicated a faulty TPS, remove it from the throttle body.
Tools Required: Socket set
Install the new throttle position sensor by aligning it properly and securing it with screws.
Reconnect the electrical connector.

5. Reinstall Throttle Body

Position the cleaned or replaced throttle body back onto the intake manifold.
Secure it with the mounting bolts using the torque wrench, applying the manufacturer’s specified torque.
Reconnect the electrical connectors and air intake duct.
