Q: What does code P2A5F mean?

Alternative Fuel Tank B Level Sensor Circuit. P2A5F indicates that the powertrain control module (PCM) has detected an electrical fault in the circuit for the alternative fuel tank B level sensor, which monitors the fuel level in a secondary or alternative fuel tank. The PCM compares the sensor signal voltage to expected values and sets the code when the circuit is out of range, open, or shorted.
