Code P00C1 Ford Description

The P00C1 diagnostic trouble code (DTC) for Ford vehicles indicates a problem with the Turbocharger/Supercharger Bypass Valve 'B' Control Circuit being too low. The turbocharger/supercharger bypass valve is responsible for redirecting excess boost pressure back into the intake system to prevent over-pressurization of the engine. When the control circuit is reading low, it means that the valve may not be functioning properly, which can lead to performance issues and potential damage to the turbocharger/supercharger system.
