Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to prevent electrical shorts during repairs.

Tools Required:

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

2. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a clean cloth to remove carbon deposits from the throttle body.
Ensure the throttle plate moves freely without obstruction.
Reinstall the intake duct securely.

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

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector from the TPS.
Remove the screws holding the TPS in place.
Install the new TPS, ensuring it aligns correctly.
Reconnect the electrical connector.

4. Check and Replace Mass Airflow Sensor (if necessary)

Disconnect the MAF sensor from the air intake duct.
Remove the screws and take out the MAF sensor.
Inspect the sensor for damage; replace it if necessary.
Reinstall the MAF sensor and reconnect the electrical connector.

5. Reconnect Battery and Clear Error Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear any stored error codes.
Perform a throttle relearn procedure if required by the vehicle's service manual.
