This summary uses the existing diagnostic information shown in full below.
This code means that the computer in your car has detected a problem with the sensor or switch that tells it if the fuel door is locked or not. It's like when a light switch doesn't work right and the light won't turn on.
The P04C5 code is triggered when the vehicle's computer detects a low voltage signal from the fuel fill door lock position sensor or switch circuit.
The fuel fill door lock position sensor or switch is responsible for indicating the lock status of the fuel door. A low circuit signal could indicate an issue with the wiring, sensor, or switch, causing the vehicle's computer to log this code.
• Fuel door not locking or unlocking properly
• Warning light on the dashboard
• Inability to refuel the vehicle
• Faulty fuel fill door lock position sensor/switch
• Damaged or corroded wiring or connectors
• Faulty control module
Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
Circuit: A complete and closed path around which a circulating electric current can flow.
• Inspect the fuel fill door lock position sensor and wiring for damage.
• Check for corrosion or loose connections at the sensor.
• Test the sensor/switch for proper operation using a multimeter.
• Replace the faulty fuel fill door lock position sensor/switch.

Sensor Issue
• Check if the fuel door is operating manually.
• Consult a professional mechanic if the issue persists.
Check with your vehicle manufacturer for warranty coverage on sensors.
This code has been reported in vehicles with electronic fuel door locking systems, particularly in models with higher mileage.
Moderate – While not immediately critical, it should be addressed to avoid inconvenience at the fuel station.
Ensure repairs are conducted by a qualified professional to maintain vehicle safety and compliance.
• Vehicle parked and engine off
• Access to the fuel door area
The fuel fill door lock position sensor is typically located near the fuel door latch mechanism.
Q: Can I still drive my car with this code?
A: Yes, but you may experience issues with the fuel door locking mechanism.
Q: Will this code affect my fuel efficiency?
A: No, this code does not directly impact fuel efficiency.
