Taurus V6-183 3.0L VIN U FI (1993)
Pressure Feedback Exhaust Sensor: Description and Operation
Differential Pressure Feedback Electronic (DPFE) EGR Sensor
Pressure Feedback Electronic (PFE) EGR Sensor
The Pressure Feedback EGR (PFE) and Differential Pressure Feedback EGR (DPFE) sensors convert a varying exhaust gas pressure signal into a
proportional analog signal which is digitized by the Powertrain Control Module (PCM). The PCM uses the signal received from the PFE or DPFE
sensor to optimize the EGR flow.
