This code means that the car's computer is having trouble getting a clear signal from the sensor that tells it if the gas cap door is open or closed.
The P04CC code is triggered when the vehicle's computer detects an inconsistent or erratic signal from the fuel fill door sensor or switch.
The P04CC code indicates that the signal from the fuel fill door open request sensor or switch is intermittent or erratic. This sensor is responsible for communicating the status of the fuel fill door to the vehicle's control module. If the signal is not consistent, the control module will set this code.
• Check engine light is on
• Fuel fill door warning light may be on
• Inability to open or close the fuel door properly
• Faulty fuel fill door sensor
• Damaged wiring or connectors
• Faulty control module
Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
OBD-II: On-Board Diagnostics, a standardized system in vehicles for self-diagnosing and reporting.
• Inspect the fuel fill door sensor and its wiring for damage.
• Check the connectors for corrosion or loose connections.
• Test the sensor for proper operation using a multimeter.
• Replace the faulty fuel fill door sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the control module if necessary.

Check with your vehicle manufacturer for specific warranty coverage on sensors and electrical components.
This code has been more prevalent in vehicles with electronic fuel door release systems.
Low – This issue does not affect immediate drivability but should be addressed to ensure proper fuel system operation.
Driving with this error code is generally safe, but it may lead to fuel system issues if not addressed.
• Vehicle must be in park.
• Fuel fill door must be operated to test the sensor.
The fuel fill door sensor is typically located near the fuel door latch mechanism.
