However i cannot locate it, can anyone give me some info as to where it is? Thanks

Re: DPFE sensor location
My manual listed P0401 as EGR related. the diagram showed the Differential Pressure Feedback Sensor (DFPE) connected to the EGR by two vacuum hoses and the wire harness go directly to the Power Control Module (PCM). I have a 99 Ranger 4.0L and the DFPE is mounted right above the driver side wheel well between the battery and the brake cylinder. When you find it, disconnect the harness and see if you're getting reference voltage. Then check all your vacuum connections including the EVR Solenoid (if equipped) which recieves EGR vacuum signal in reference to the vacuum source.

Re: DPFE sensor location
when u locate it just look down the tube holes and look to see if there is crud or dirt in there.. i have replaced 15 or 20 just by looking down the tubes and its always worked...

Re: DPFE sensor location
I was looking at a 4.0 liter tonight and had alittle problem finding it to. I remember all you have to do is look down near your egr tube and you should see two small hoses attach to the main hose coming up to your dpfs. This dpfs was lot smaller than the old ones were. Its about 1.5 inch square with the two line going to it. located on the left hand side of engine valve cover fwd side. Good luck
