What does code P022F mean?

Q: What does code P022F mean?

Charge Air Cooler Bypass Control B Circuit High. P022F means the powertrain control module (PCM) has detected a high-voltage condition on the electrical circuit that controls the charge air cooler bypass valve, which is the flap that routes intake air around or through the intercooler. The PCM commands the valve to move and then watches the circuit voltage; when the voltage stays above the expected range for the commanded state, it logs this code.
