Q: What does code P2A26 mean?

Alternative Fuel Tank Shutoff Valve C Control Circuit/Open. P2A26 indicates 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 'C'. This valve is used on vehicles with alternative fuel systems to isolate the fuel tank for safety and to manage fuel flow, and the PCM expects a specific voltage or current on the control wire when commanding the valve. The code is set when the PCM sees a condition outside the expected range, typically an open circuit or a short to ground or power.
