Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during the repair.
Allow the engine to cool down if it has been running.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft brush, clean rags.
Remove the air intake duct to access the throttle body.
Spray throttle body cleaner onto the throttle body and use a soft brush to gently scrub away carbon deposits.
Wipe clean with a rag, ensuring there are no residues left.
Reattach the air intake duct securely.

3. Replace the Throttle Position Sensor (if faulty)

Tools Required: Socket set, wrench set, torque wrench.
Disconnect the electrical connector from the throttle position sensor.
Remove the screws or bolts securing the TPS and take it out.
Install the new throttle position sensor, ensuring it is properly aligned.
Tighten the screws or bolts to the manufacturer's specifications (usually around 7-10 ft-lbs).
Reconnect the electrical connector.

4. Inspect and Replace Accelerator Pedal Position Sensor (if faulty)

Tools Required: Socket set, torque wrench.
Disconnect the battery.
Remove the accelerator pedal assembly by unscrewing the mounting bolts.
Disconnect the electrical connector from the accelerator pedal position sensor.
Replace the sensor with a new one, reconnecting the electrical connector.
Reinstall the pedal assembly and secure it with bolts.
