2. Inspect and Clean Throttle Body

Tools Required: Throttle body cleaner, soft brush, cloths.
Remove the air intake duct from the throttle body by loosening the clamps.
Spray throttle body cleaner into the throttle body and use a soft brush to scrub away carbon deposits.
Wipe clean with a cloth and ensure the throttle plate opens and closes freely.
Reattach the air intake duct securely.

3. Inspect Throttle Cable

Tools Required: Socket set.
Locate the throttle cable at the accelerator pedal and throttle body.
Examine the cable for any signs of wear, binding, or kinks.
If damaged, replace the throttle cable with a new one.

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

Tools Required: Multimeter, socket set.
Disconnect the electrical connector from the throttle position sensor.
Use a multimeter to check the resistance values according to the service manual specifications.
If the TPS is faulty, remove it by unscrewing the mounting bolts and replace it with a new sensor.
Reconnect the electrical connector.
