Solution

1. Preparation

Gather tools and parts needed.
Disconnect the battery to prevent electrical shorts.
Allow the engine to cool before starting work.

Tools Required:

OBD-II scanner
Multimeter
Socket set
Screwdrivers
Throttle body cleaner
Torque wrench

2. Clean the Throttle Body

Remove the air intake duct by loosening the clamps and disconnecting any sensors.
Detach the throttle body by removing the mounting bolts (usually 4-6 bolts).
Clean the throttle body using throttle body cleaner and a soft cloth. Ensure the butterfly valve operates smoothly.
Reinstall the throttle body and tighten the bolts to the manufacturer’s torque specifications.

3. Replace Throttle Position Sensor (if needed)

If the TPS is faulty, disconnect the electrical connector and remove the screws holding the sensor in place.
Install the new TPS, ensuring it aligns correctly with the throttle body.
Reconnect the electrical connector.

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

Locate the accelerator pedal position sensor under the dashboard.
Disconnect the electrical connector and remove the mounting screws.
Install the new sensor and reconnect the electrical connector.

5. Reconnect Battery and Reset ECU

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any error codes and reset the ECU.
