Q: What does code P22C5 mean?

Turbocharger Compressor Outlet Valve Control Circuit/Open. P22C5 indicates that the powertrain control module (PCM) has detected an open circuit or excessive resistance in the control circuit for the turbocharger compressor outlet valve, which is often an electronic recirculation or bypass valve. The PCM commands the valve to open or close to manage boost pressure and prevent compressor surge, but the circuit's electrical feedback does not match the expected command.
