What does code P2A7C mean?

Q: What does code P2A7C mean?

Alternative Fuel Hydraulic Pressure Sensor Circuit Low. P2A7C indicates that the powertrain control module (PCM) has detected a voltage signal from the alternative fuel hydraulic pressure sensor that is lower than the expected range for the current operating conditions. This sensor monitors hydraulic pressure in alternative fuel systems, and a low signal typically points to a circuit fault, a sensor issue, or low actual pressure.
