EGR Differential Pressure Sensor
FUNCTIONS WITHIN THE SYSTEM
EGR differential pressure sensor is connected to EGR valve with pressure tube.
INDIVIDUAL FUNCTION WITHIN THE SYSTEM
EGR differential pressure sensor measures the differential pressure between upstream and downstream of the EGR valve. It converts into a voltage signal.
INDIVIDUAL OPERATION
ECM receives the signal via engine communication and estimates the EGR valve opening ratio or EGR valve position.
COMPONENT LOCATION
The EGR differential pressure sensor is mounted on the exhaust side of the cylinder head.
