Q: What does code P2A22 mean?

Alternative Fuel Tank Shutoff Valve B Control Circuit/Open. P2A22 is a generic powertrain code indicating that the powertrain control module (PCM) has detected an open circuit or control fault on the control circuit for the alternative fuel tank shutoff valve B. The PCM commands the valve to open or close during fuel system transitions, and when the circuit current or voltage falls outside the expected range, the PCM stores this code and may disable alternative fuel operation.
