Solution

1. Preparation

Tools Required: OBD-II scanner, screwdriver set, socket set, multimeter, throttle body cleaner, cleaning cloths.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Inspect Throttle Body

Remove the air intake duct connected to the throttle body by loosening the clamps and disconnecting any sensors.
Clean the throttle body using throttle body cleaner and a cloth to remove any carbon deposits or obstructions.
Ensure the throttle plate moves freely without sticking.

3. Check Throttle Cable

Locate the throttle cable connected to the throttle body.
Inspect the cable for fraying or binding. If damaged, replace the throttle cable.
If the cable is intact, ensure it is properly adjusted and has the correct amount of slack.

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

Disconnect the electrical connector from the throttle position sensor.
Using a multimeter, check the resistance and voltage output of the TPS while moving the throttle plate.
If the TPS readings are out of specification, replace the throttle position sensor.

5. Reassemble and Test

Reattach the air intake duct and ensure all connections are secure.
Reconnect the negative terminal of the battery.
Start the engine and allow it to idle, checking for smooth throttle response.
