Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, cleaning supplies (throttle body cleaner, rags).
Ensure the vehicle is parked on a level surface, and the engine is cool before starting.

2. Disconnect Battery

Locate the negative terminal of the battery.
Use a socket wrench to loosen and remove the negative cable from the battery terminal.
Safety Warning: Always disconnect the battery before working on electronic components to avoid short circuits.

3. Clean Throttle Body and TPS

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a rag to clean the inside of the throttle body and the throttle plate. Ensure no debris enters the intake system.
Inspect the TPS for any signs of wear or damage; replace if necessary.

4. Reconnect Battery

Reconnect the negative battery terminal and tighten it securely.
Ensure that all components are properly reinstalled and secured.

5. Throttle Position Sensor Calibration

Start the engine and let it idle for a few minutes.
With the engine running, slowly accelerate and decelerate to allow the ECU to learn the new position of the throttle.
Drive the vehicle normally for a short distance to ensure the TPS is functioning correctly.
