This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is getting a signal that the fuel level is too high, which might not be true. It's like your gas gauge is saying the tank is full when it's not.
The P0463 code indicates that the fuel level sensor is sending a voltage signal to the engine control module (ECM) that is higher than expected, suggesting an incorrect fuel level reading.
The fuel level sensor is part of the fuel pump assembly and is responsible for sending a voltage signal to the ECM that corresponds to the amount of fuel in the tank. A 'circuit high' condition means that the voltage is higher than the expected range, which could be due to a faulty sensor, wiring issues, or a problem with the ECM.

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect fuel system components
• Keep electrical connections clean and secure
• Use quality fuel to prevent sensor contamination
Sensor Issue
• Monitor fuel gauge for accuracy
• Address Check Engine Light promptly
Repairs may be covered under the vehicle's powertrain warranty if applicable.
This code is commonly associated with aging vehicles where the fuel level sensor has worn out or been damaged.
Moderate – While the vehicle may still operate, inaccurate fuel readings can lead to running out of fuel unexpectedly.
Driving with an inaccurate fuel gauge can lead to unexpected stops and potential safety hazards.
• Vehicle parked on a level surface
• Ignition in the 'On' position
The fuel level sensor is typically located within the fuel tank, attached to the fuel pump module.
Q: Can I drive with a P0463 code?
A: Yes, but it's not recommended as you may run out of fuel unexpectedly due to inaccurate gauge readings.
Q: How do I reset the Check Engine Light after repairing the issue?
A: You can use an OBD-II scanner to clear the code after confirming the issue is resolved.
