This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the sensor that tells how much fuel is in the tank is getting too much electricity. It's like when a toy gets too many batteries and doesn't work right.
The P25DA code is triggered when the Powertrain Control Module (PCM) detects a high voltage condition in the Fuel Level Sensor C circuit.
This code indicates that the voltage reading from the Fuel Level Sensor C circuit is higher than the expected range. The fuel level sensor is responsible for measuring the amount of fuel in the tank and sending this information to the vehicle's computer. A high circuit reading suggests an electrical issue, such as a short circuit or a faulty sensor.
• Inaccurate fuel gauge readings
• Check Engine Light illuminated
• Possible fuel delivery issues
• Faulty fuel level sensor
• Wiring issues such as a short to voltage
• Defective PCM
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use a scan tool to verify the code and check for other related codes.
• Inspect the wiring and connectors for damage or corrosion.
• Test the fuel level sensor for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the fuel level sensor if faulty.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Silverado
• GMC Sierra
• Ford F-150
• Regularly inspect and maintain fuel system components.
• Avoid overfilling the fuel tank.
• Keep electrical connections clean and secure.
Sensor Issue
• Check your fuel gauge regularly for accuracy.
• If the Check Engine Light is on, have the vehicle inspected promptly.
Repairs may be covered under the vehicle's powertrain warranty if applicable.
This code has been associated with vehicles experiencing electrical issues in the fuel system, often due to wiring problems.
Moderate – While the vehicle may still be drivable, inaccurate fuel readings can lead to unexpected fuel shortages.
Driving with an inaccurate fuel gauge can lead to running out of fuel unexpectedly, which could be dangerous.
• Vehicle is turned on.
• Fuel system is pressurized.
The fuel level sensor is typically located inside the fuel tank.
Q: Can I drive with a P25DA code?
A: While you can drive with this code, it's not recommended as it can lead to inaccurate fuel readings.
Q: How do I reset the Check Engine Light after fixing the issue?
A: The Check Engine Light can be reset using an OBD-II scanner after the issue is resolved.
