The crankcase ventilation sensor is a hall effect sensor mounted on the crankcase ventilation hose at the turbocharger air inlet connection. The crankcase ventilation separator is mounted on the driver side rocker cover, with the crankcase ventilation hose connecting the separator to the crankcase ventilation sensor at the air inlet of the turbocharger. The crankcase ventilation hose on the separator side has a tamper proof connector. The crankcase ventilation sensor monitors the crankcase ventilation hose connection at the air inlet of the turbocharger. The crankcase ventilation sensor signal to the PCM indicates if the crankcase ventilation hose is connected or disconnected.
