Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner onto a clean cloth and wipe the inside of the throttle body to remove carbon buildup.
Ensure the throttle plate moves freely; if it sticks, further cleaning may be required.
Reattach the air intake duct and torque to specifications (usually around 7-10 ft-lbs).

3. Check and Adjust Throttle Cable

Locate the throttle cable connected to the throttle body.
Inspect for any signs of wear or binding; if damaged, replace the cable.
If the cable is intact, adjust the tension if necessary according to the manufacturer's specifications.

4. Inspect the Throttle Position Sensor (TPS)

Disconnect the TPS connector and remove the sensor using a Torx screwdriver.
Test the TPS with a multimeter to ensure it provides a smooth voltage range as the throttle is opened.
If faulty, replace the TPS with a new unit and torque to manufacturer specifications.

5. Reassemble and Final Checks

Reconnect the negative battery terminal.
Start the engine and let it idle to ensure proper operation.
Check for any error codes or warning lights that may reappear.
