DPFE Sensor
For those of you who need to replace the DPFE sensor you can get it from Ford for their quoted price of $141.56 or go to Napa and get their EGR Pressure Feedback Sensor for $55.80. Same sensor, slightly different name. While your down at Ford you might want to order a new set of Firestones while your there.

DPFE Sensor
What year is your truck? Because on my 95 Explorer this part went out and Autozone had it for $71.50 but had to order it not in stock and the Dealership had it in stock for $72. So I bought it from the dealership, so just wondering.

My289,
Mine is a 94 Explorer XLT with 4.0L engine. I saw the one from Autozone also, but like you state, it was more expensive. Apparently dealers charge whatever they feel they can get away with. For what its worth the dealer who quoted $141.56 was Heller Ford in Escondido, CA. I put the NAPA part on last night and the code 332 I was getting has not repeated.
By the way, the one I got from NAPA looks identical to the one I replaced, right down to having the OEM number on it.

What Error code did you get? I'm getting a 402 or 420, the EGR valve. I had the O2 sensor replaced over a year ago, but the Check Engine light is on again and I was told it's the EGR valve. Any input greatly appreciated.
FYI, I have a '96 XLT V8.

I believe the codes for a 94 differ from the 96 but for discussion sakes it was 322 "EGR valve not opening". I first confirmed there was nothing wrong with the EGR valve itself. Then I confirmed I had a voltage at the EGR switch and measured the switch's coil resistance. It appeared fine. Then I monitored the DPFE switch input voltage (Okay) and output voltage while driving it and the switch was not registering the rise in voltage it should produce as the backpressure changes due to the EGR valve opening. This led me to believe the switch was the problem but it was still a gamble because I did not have any way to be sure the valve was aactually opening when it should. I gambled the valve was opening and the DPFE switch was not acknowledging it and guessed right. I was using the Haynes manual for reference.
Hope this helps.

I have '98 Ford Expedition. When my check engine light came on, I took in to my Ford dealer and they told me "Needs Dpfe sensor, clean ports, & reprogram PCM". I found the dpfe sensor and figured I could replace it myself. But what does "clean ports, and reprogram PCM" involve. Is this something I can do myself?
Thanks for any help.

If the 98 is anything like the 94 they are talking about cleaning the two tubes and their connections that hook up to the sensor. They have a tendency to clog over time. I am not sure how codes are cleared on a 98. I would imagine it is detailed somewhere here on the message board. Might be as simple as disconnecting the battery for a few minutes.

DPFE Sensor
I picked mine up at the counter at Napa. They had it in stock. The number on the one I got from them matched the one I replaced but, come to think of it, I don't know if the one I replaced was OEM. Regardless if it looks the same it probably is. Ford will sometimes change their numbers as a product is upgraded or improved. My main intent was to let everyone know that Ford calls it a DPFE (Differential Pressure Feedback Electronic)sensor and Napa calls it as an EGR Pressure Feedback Sensor. If that is what Napa sold you you should be fine.

I am having the same problem with my Check Engine Light. It just stays on now. I have a big problem getting parts since I live in Belgium (for another six months). I also have a 96 Explorer XLT, V8, 5.0L. Unless I am mistaken, there is no DPFE Sensor, but instead it is called an EGR Valve Position Sensor. Did you get your problem fixed and if so, what did you do? Thanks.

I am not sure the V8 is the same but post #4 on this thread explains how I went about it. Check all the hoses going to the EGR for blockages first. If your EGR is not functioning you probably can drive it 6 months without much of a problem as long as you aren't having it smogeed. If its the sensor I don't think it would matter anyway other then the annoyance of having the light on. Did you check the codes. I think for the 96 you have to have a code reader to do so. 94's only needed a jumper. Just my $.02.
