Pressure Feedback Exhaust Sensor: Description and Operation

Pressure Feedback Electronic (PFE) EGR Sensor

The Pressure Feedback EGR (PFE) Sensor is a ceramic capacitive-type pressure sensor. Exhaust pressure or vacuum is converted into a proportional
analog voltage signal, which is digitized by the Electronic Control Assembly (ECA).  The ECA uses the signal received from the PFE sensor to compute
optimum EGR flow rate, as well as to monitor EGR flow.
