2. Remove the Fuel Tank Pressure Sensor

Locate the fuel tank pressure sensor, usually found on the top of the fuel tank.
Disconnect the electrical connector from the sensor.
Use an appropriate socket to remove the screws or bolts securing the sensor to the fuel tank.
Carefully pull the sensor out of its mounting position.

3. Inspect and Replace

Inspect the old fuel tank pressure sensor for signs of wear or damage.
Compare the old sensor with the new replacement sensor to ensure compatibility.
Install the new sensor by aligning it properly with the mounting position and securing it with screws or bolts to the manufacturer’s specified torque settings.

4. Reconnect Electrical Connections

Reattach the electrical connector to the new fuel tank pressure sensor.
Ensure that the connection is secure and that there are no loose wires.

5. Reconnect Battery and Test

Reconnect the vehicle's battery.
Start the engine and monitor the dashboard for the check engine light. Ensure it is off after a few moments.
Test drive the vehicle to confirm that all symptoms have been resolved.
