Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool down before starting any work.

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 carbon buildup or debris.
Use throttle body cleaner and a soft cloth to clean the interior surfaces, ensuring the throttle plate moves freely.
Reinstall the air intake duct and ensure all connections are secure.

3. Check and Replace Throttle Cable (if necessary)

Locate the throttle cable connected to the accelerator pedal and throttle body.
Inspect for any signs of damage or binding; if found, proceed to replace.
To replace, disconnect the old cable from the throttle body and accelerator pedal.
Route the new throttle cable in the same path as the old one, ensuring it is not pinched or kinked.
Attach the new throttle cable securely to both the throttle body and accelerator pedal.

4. Test Throttle Position Sensor

Locate the throttle position sensor on the throttle body.
Disconnect the sensor's electrical connector.
Use a multimeter to measure the voltage across the sensor terminals while manually moving the throttle plate.
Compare readings with manufacturer specifications; if out of range, replace the throttle position sensor.

5. Reconnect and Test

Reconnect the battery.
Start the engine and check for any abnormal throttle response.
Conduct a test drive to verify that the throttle operates smoothly and there are no warning lights.
