The DPFE sensor is the back pressure sending sensor that controls the EGR valve.
The Location ( on a 99 E150 ) is on the driver's side upper rear area of the engine.
It is best to remove the inside engine cover to get to it. You can see it from the hood area if you shine a light and look back to the area looking above the mass air flow sensor then along where the 3rd back spark plug is. Look for a silver rectangular device about 2 " tall X 4" long 1" thick. It has a plug to the rear on the face and two 3/8" hoses coming out and going down from it. To replace or check voltage etc. take the inside engine cover off ( some people refere to this as the "Dog House" ) . Hope this helps. I know I could not find the location on the net so I thought I would share.
on the 4.2l it is on top of the egr valve. you have to buy the whole thing its about 170 bucks.
On my 1995 Ford Explorer with the 4.0 liter OHV engine the DPFE sensor ( differential / or delta pressure feedback Egr sensor ) is located on the upper intake manifold on the drivers side of the engine
I'm not a mechanic / technician but I had the DPFE sensor changed on my Ford Explorer . As far as I know it is used to control the amount the Exhaust Gas Recirculation ( EGR ) valve opens
P1401 is DPFE sensor circuit high, check out this tutorial to replace the sensor on your Ford
YES - www.motorcraft.com lists a DPFE sensor for all available engines on a 1996 Ford Ranger
On the 4.0 L - OHV engine , the DPFE sensor is on the drivers side of the engine , mounted below the idle air control valve
Ford is the only American car company that uses a DPFE sensor. GM dpfe sensor are built into the EGR.
Where is the DPFE sensor located in a 1999 Ford Exployer? I had my oil changed yesterday and was told that the hose connected to this sensor is off.
where is the DPFE sensor located on a 2002 ford crown victoria?
There is only one coolant temperature sensor on a 1999 Ford E150 6 cylinder. The sensor is on the front of the engine just below the valve cover.
From what I understand , it is the sensor that the Powertrain Control Module uses to determine exactly how much the EGR valve opens at all driving conditions
