Contour L4-122 2.0L DOHC VIN 3 SFI (1995)
Differential Pressure Feedback EGR Sensor: Description and Operation
Differential Pressure Feedback EGR (DPFE) Sensor
PURPOSE
The Differential Pressure Feedback (DPFE) EGR sensor converts a varying exhaust pressure signal into a proportional analog voltage which is
digitized by the Powertrain Control Module (PCM).
OPERATION
The PCM uses the signal received from the DPFE sensor to compute the optimum EGR flow.
