Operation
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 Powertrain Control Module (PCM) uses data from the CP sensor to determine the condition of the crankcase breather
(ventilation) filter. The PCM can also determine if a crankcase breather (ventilation) filter is present.
