Where is the DPFE sensor hose on a 2000 Ford Focus?

Answer 1

Feedback EGR Sensor The DPFE sensor is a ceramic, capacitive type pressure transducer. The sensor outputs a voltage to the PCM in direct proportion to the pressure drop across the orifice in the EGR pipe. In this way the PCM can make an accurate assessment of the gas flow through the tube. Two different sensors are in use, one metal cased and the other plastic. These sensors should not be interchanged - further, some sensors have a modified voltage output.
