How to replace the dpfe sensor on a Ford F150?
Learn how to turn off the the Ford F150 Check engine or Service engine light Code P1401. Replace the EGR sensor or the DPFE sensor to fix the problem. Buy the Ford Motorcraft part for this replacement. I had to replace the generic sensor a year later. Motorcraft part has been working good. Disclaimer:
Why is the Ford dpfe sensor and EGR system important?
To do that, they have developed exhaust gas re-circulation (EGR) valves and sensors to detect how well the EGR valve is working. The sensing portion of the system is important because the exhaust contains soot, and that soot can clog up the metering portion of the EGR valve.
What to do if your dpfe sensor is bad?
Remove both hoses from the DPFE sensor then re-attach the hose that used to go to the EGR Valve, to the “Ref” hose port on the DPFE Sensor. Doing this sort of tricks the system so that instead of opening the EGR valve when the PCM sends the signal, it will now apply vacuum to the “Reference” sensor for the DPFE.
Where does exhaust gas go in a Ford dpfe?
The vacuum pulls up on the diaphragm, lifting the pintle off the pintle seat. With the pintle off its seat, exhaust pressure forces exhaust gas up through the EGR tube, the EGR valve, and into the intake manifold at port 4. On the way up to the EGR valve, the exhaust gas passes through a restriction.

Where are the vacuum hoses on a dpfe sensor?
The sensor is a small square with two vacuum hoses on the bottom and a wire harness coming out from the side. The location will vary slightly from make and model. Check your repair manual for exact location and a detailed diagram. Disconnect the two vacuum hoses from the sensor by giving them a firm tug. Turn the ignition key to the “On” position.
