FUEL SYSTEM
RAIL PRESSURE SENSOR (RPS)
INSPECTION
E0734AD3
FUNCTION AND OPERATION PRINCIPLE
Rail Pressure Sensor (RPS) is installed at the end of the
common rail and measures the instantaneous fuel pres-
sure in the common rail by using its diaphragm. Its sens-
ing element (semiconductor device) mounted on the di-
aphragm converts the fuel pressure to an electric signal.
