What does code P22CF mean?

Q: What does code P22CF mean?

Turbocharger Turbine Inlet Valve Control Circuit/Open. P22CF indicates that the powertrain control module (PCM) has detected an open circuit or abnormal voltage on the control circuit for the turbocharger turbine inlet valve, which is often part of a variable geometry turbocharger (VGT) or a wastegate control solenoid. The PCM commands the valve to move and monitors the circuit for expected electrical feedback; when the signal is missing or out of range, it sets this code and typically disables the valve's active control.
