Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and a flashlight.
Ensure the vehicle is turned off and in a safe working environment.

2. Inspect Charge Port Door

Visually check the charge port door for any debris or obstructions.
Open and close the charge port door manually to ensure it moves freely.

3. Check Alignment

If misaligned, adjust the hinges or mounting points of the charge port door.
Tighten any loose screws or fasteners that may affect door operation.

4. Test Charge Port Door Sensor

Disconnect the charge port door sensor connector.
Use a multimeter to check for voltage at the connector with the vehicle on.
- Expected voltage should be around 12V.
If there is no voltage, trace the wiring back to the control module for faults.

5. Replace Charge Port Door Sensor (if necessary)

If the sensor is faulty, remove it by unscrewing the retaining screws.
Replace it with a new sensor and reconnect the wiring.
Ensure all connections are secure and check for proper operation.
