What does code P2A93 mean?

Q: What does code P2A93 mean?

Alternative Fuel Tank Select Valve A Control Circuit Low. P2A93 indicates that the powertrain control module has detected a low-voltage condition on the control circuit for the alternative fuel tank select valve A, which is the valve that switches fuel supply between the primary and alternative fuel tanks. The computer expects to see a voltage near battery voltage on the control side of the valve circuit when the valve is commanded off, but the measured voltage is below the calibrated threshold, indicating a short to ground or an open circuit.
