What does code P224F mean?

Q: What does code P224F mean?

Alternative Fuel Tank Shutoff Valve A Control Circuit High. P224F means the powertrain control module (PCM) has detected a high-voltage condition on the control circuit for the alternative fuel tank shutoff valve, often called valve A. The PCM commands the valve to close or open, and the circuit voltage stays above the expected threshold, so the computer flags the circuit as stuck high.
