Q: What does code P22C8 mean?

Turbocharger Compressor Outlet Valve Stuck Open. P22C8 indicates that the powertrain control module (PCM) has detected a fault in the turbocharger compressor outlet valve circuit, specifically that the valve is stuck open when it should be closed or modulated. The PCM commands the valve to a position and monitors the circuit and often the resulting boost pressure; if the valve does not respond as expected or the circuit indicates an open condition, the code is stored.
