What does code P2A2C mean?

Q: What does code P2A2C mean?

Alternative Fuel Tank Shutoff Valve D Control Circuit Low. P2A2C means the powertrain control module has detected a low-voltage condition on the control circuit for the alternative fuel tank shutoff valve, identified as valve D. The circuit is reading below the expected voltage threshold, which usually points to a short to ground, an open circuit, or a failed valve solenoid rather than a mechanical fuel delivery problem.
