Solution

1. Preparation

Tools Required: OBD-II scanner, flathead screwdriver, torque wrench, cleaning supplies (throttle body cleaner), safety gloves.
Ensure the vehicle is parked on a level surface and the engine is off. Disconnect the battery negative terminal to prevent electrical shorts.

2. Disconnect the Throttle Position Sensor

Locate the throttle position sensor on the throttle body.
Using a flathead screwdriver, carefully release the locking tab of the connector and unplug the sensor.
Remove any mounting screws or bolts securing the TPS, noting their locations for reinstallation.

3. Clean the Throttle Body

Use throttle body cleaner to remove any carbon buildup around the throttle body and the sensor mounting area.
Wipe clean with a lint-free cloth and allow the area to dry completely.

4. Install the New or Existing Throttle Position Sensor

Position the throttle position sensor back onto the throttle body and secure it with the mounting screws/bolts. Torque to manufacturer specifications (usually around 8-10 ft-lbs).
Plug the electrical connector back into the TPS until it clicks into place.

5. Reset the Throttle Position Sensor

Reconnect the battery negative terminal.
Turn the ignition key to the "ON" position without starting the engine for about 2 seconds, then turn it off again.
Repeat this process three times to allow the ECU to recognize the throttle position sensor.

6. Test Drive the Vehicle

Start the engine and allow it to idle for a few minutes.
Test drive the vehicle to ensure smooth acceleration and proper throttle response.
