Differential Pressure Feedback EGR (DPFE) Sensor Operation
Differential Pressure Feedback Electronic (DPFE) EGR Sensor:
The Differential Pressure Feedback EGR (DPFE) sensor converts a varying exhaust gas pressure signal into a proportional analog which is digitized by the Electronic Control Assembly (ECA). The ECA uses the signal receives from the DPFE sensor to optimize the EGR flow.
