Crankcase Pressure Sensor
FUNCTIONS WITHIN THE SYSTEM
ECM detects malfunction of crankcase ventilation system by operating crankcase ventilation valve and control inside pressure of crankcase.
INDIVIDUAL FUNCTION WITHIN THE SYSTEM
Crankcase pressure sensor outputs pressure difference between the internal pressure of engine crankcase and the ambient pressure.
INDIVIDUAL OPERATION
Crankcase pressure sensor use piezoelectric element on its diaphragm and output voltage changes by changing of relative pressure inside and outside of engine.
COMPONENT LOCATION
The crankcase pressure sensor is installed to the upper of front cover.
