Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is turned off.
Disconnect the battery to prevent any electrical issues.

2. Inspect Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Clean the throttle body using throttle body cleaner and a soft cloth to remove carbon buildup.
Check the throttle plate for free movement; manually open and close it to ensure it’s not sticking.

3. Examine Throttle Pedal Assembly

Remove the plastic cover from the throttle pedal assembly if applicable.
Inspect the pedal linkage for any obstructions or binding.
Lubricate pivot points with a suitable lubricant if there are signs of sticking.

4. Test Throttle Position Sensor

Disconnect the throttle position sensor connector.
Using a multimeter, measure the resistance across the sensor terminals while slowly moving the throttle plate.
Compare readings to specifications in the service manual; replace the sensor if readings are out of range.

5. Reassemble and Reconnect

Reattach the throttle body duct and ensure all connections are secure.
Reconnect the battery.
Clear any stored error codes using the OBD-II scanner.
