DIFFERENTIAL PRESSURE FEEDBACK (D.P.F.) EGR SENSOR CONSTRUCTION/OPERATION [YF (2.0L Zetec)]
BUE014018210N06
• Installed near the EGR valve.
• Induction pipes that go from downstream and upstream of the orifice in the middle of the EGR pipe are connected to the differential pressure feedback EGR sensor, and the sensor converts the difference in pressure formed downstream and upstream of the orifice into voltage.
• When the piezoelectric element in the sensor is strained due to differential pressure, an electric potential difference is created. The larger the strain, the higher the output voltage.
