This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble reading how much fuel is in a special tank that uses a different kind of fuel, not regular gas.
The P2A65 code is triggered when the vehicle's computer detects a problem with the signal from the level sensor in the alternative fuel tank C, indicating that the sensor is not providing a valid reading.
The alternative fuel tank level sensor is responsible for measuring the amount of alternative fuel in the tank and sending this information to the vehicle's engine control module (ECM). If the ECM detects that the sensor's signal is out of the expected range or not performing as expected, it will set the P2A65 code.
• Check engine light is on
• Inaccurate fuel gauge reading
• Possible drivability issues if the vehicle relies on the alternative fuel
• Faulty fuel level sensor
• Wiring issues such as damaged wires or poor connections
• Faulty ECM or software issues
ECM: Engine Control Module, the computer that controls engine functions
OBD-II: On-Board Diagnostics, a system that monitors vehicle performance
• Use an OBD-II scanner to confirm the code
• 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 faulty fuel level sensor
• Reprogram or replace the ECM if necessary
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regularly inspect and maintain the fuel system
• Ensure proper connections and wiring integrity
• Use quality fuel to avoid sensor contamination
Sensor Issue
• Do not ignore the check engine light; get it checked soon
• Monitor fuel levels manually if possible
• Consult a professional mechanic if unsure
Check with your vehicle manufacturer as some components may be covered under warranty.
This code is relatively uncommon and typically associated with vehicles using alternative fuels.
Moderate – It should be addressed soon to avoid potential drivability issues.
Driving with an unresolved issue related to fuel sensors can lead to unexpected vehicle behavior. Always address check engine light warnings promptly.
• Vehicle must be running
• Ensure alternative fuel tank is not empty
The alternative fuel tank level sensor is typically located inside the alternative fuel tank, which may be under the vehicle or in the trunk area.
Q: Can I still drive my car with this code?
A: Yes, but it's best to have it checked soon to avoid potential issues.
Q: Will this affect my fuel economy?
A: It might, as the vehicle may not accurately track fuel usage.
