Q: What does code P2A24 mean?

Alternative Fuel Tank Shutoff Valve B Control Circuit Low. P2A24 indicates that the powertrain control module has detected a low-voltage condition on the control circuit for the alternative fuel tank shutoff valve B, which is used to isolate the alternative fuel tank from the engine during certain conditions. The computer monitors the circuit for expected voltage and sets this code when the signal is below the normal threshold, indicating a short to ground, an open circuit, or a faulty component.
