Basic error definition

Crankcase Ventilation System Disconnected

Cause of DTC

When the engine is running and not in boost, the crankcase ventilation hose provides filtered clean air from the clean air tube to the PCV system through the crankcase. During boost the flow reverses and PCV vapors are pushed from the crankcase, through the tube, into the clean air tube, then into the Supercharger, and eventually into the Intake Manifold where they are burned. If the crankcase ventilation hose is disconnected from the clean air tube, PCV vapors will leak into the atmosphere whenever the engine is in boost.
