Solution

1. Preparation

Tools Required: Socket set, screwdriver set, throttle body cleaning spray, multimeter, and rags.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery's negative terminal to ensure safety.

2. Inspect and Clean Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Inspect the throttle body for any buildup of dirt or carbon.
Spray throttle body cleaner into the throttle body while manually opening the throttle plate to clean both sides.
Wipe away any residues with a rag.
Reattach the air intake duct securely.

3. Check Throttle Cable (if applicable)

Locate the throttle cable at the throttle body and check for any binding or fraying.
If the throttle cable is damaged, remove it by detaching it from the throttle body and the accelerator pedal linkage.
Install a new throttle cable and adjust it according to the manufacturer's specifications.

4. Test Throttle Position Sensor (TPS)

Locate the TPS on the throttle body and disconnect the electrical connector.
Use a multimeter to test the sensor's output voltage while moving the throttle plate.
If the readings are outside the specified range, replace the TPS.

5. Reconnect Battery and Final Checks

Reconnect the negative terminal of the battery.
Start the engine and let it idle to ensure the throttle operates smoothly.
