What does code P22D0 mean?

Q: What does code P22D0 mean?

Turbocharger Turbine Inlet Valve Control Circuit Low. P22D0 indicates that the powertrain control module has detected a low-voltage condition on the control circuit for the turbocharger turbine inlet valve, which is the valve that regulates exhaust gas flow to the turbine. The circuit is reading below the expected voltage threshold, which can prevent the valve from actuating and may reduce turbocharger performance.
