Ok. Everyone talks about DPFE sensor. Well, I have never heard that acronym. What does it stand for? D_____ P_____ F______ Egr? I have the wonderful p0401 EGR Low flow code. But I also want to go ahead and change that sensor but I cant when I dont know the name for it.

IIRC, it stands for Differential Pressure Flow EGR. If you go to a Ford Parts Department and ask them for a DPFE sensor for your year Ranger, they'll know what you're talking about (at least, the one I went to did). Be prepared, it cost me about $75.
Oh, one other thing. I had the same code on my truck last fall. Checked under the hood, and the stinkin DPFE sensor had MELTED!!!! Replaced it, and everything was fine. Nobody could tell me why it happened either.

 

OK as stated above, well done Tracy!, your gonna wanna go get your self a new one. But in advance, get the plastic one because the aluminum one turns to junk faster....plus if your careful you can take the plastic one apart, clean it and then reinstall it if your p0401 CEL ever comes back. Mine costed me $65 from Napa.

 

Yeah, good call Andrew, forgot to mention that. The metal ones are junk, you want the plastic one. The plastic one I got was a completely different beast than the original one on the truck. Smaller and heavier than original. Different part number too.
Hope we helped!

 

I just had this problem fixed by ford. Under Warranty for me. Only a 50$ part.

 

Good question Ski, and welcome to the site friend.

 

DPFE sensor means Differential Pressure Feedback EGR sensor and those are the names to use at a Ford dealer.

If you are shopping at an auto parts store, some of them sell aftermarket DPFE's that are catalogued as "EGR Position Sensors". The name is incorrect because a DPFE is a flowrate sensor - the EGR Position Sensor name is taken from earlier systems that actually had position sensors mounted on top of the EGR.

 

I took my truck in for inspection and to get the sensor replaced also last week, cost me 50$ because of my extended warranty, fixed the light. I did get the larger plastic one too!

 

well, the one that is on there now is a larger plastic one. however, I hope that I'm thinking of the right part. does it have a circular cap looking thing on it?

 

Your original 2002 DPFE should look like this:



The replacement may look the same or it might be larger.

 

I swear Bob, where on earth do you come up with all these awsome diagrams!

 

I don't remember where I got that one. When I see something that looks good I save it.

 

henry ford was reincarnated as bob lol

 

I believe it...

Imagine this: We start a library type thing, only its Bob in person....we can each check him out of this "library" for one week a year.....imagine the possabilities!!!!

 

lets see.. i'll need bob for a weekend in early july for my EATC. There, made my reservation

 

See its a friggin awsome idea isnt it!
