Crankcase Pressure Sensor - 6.7L

OPERATION





The Crankcase Pressure (CP) Sensor (5) is mounted on the valve cover (4). The CP sensor monitors crankcase pressure that builds up as the result of combustion gas blow-by. The Engine Control Module (ECM) uses data from the CP sensor to determine the condition of the crankcase breather (ventilation) filter. The ECM can also determine if a crankcase breather (ventilation) filter is present.
