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.
