What does code P22C6 mean?

Q: What does code P22C6 mean?

Turbocharger Compressor Outlet Valve Control Circuit Low. P22C6 indicates that the powertrain control module (PCM) has detected a low-voltage condition on 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, and the circuit voltage stays below the expected threshold, so the computer flags the circuit as faulty.
