The DPFE (Differential Pressure Feedback EGR) sensor on a Ford Taurus is typically located near the EGR valve, often mounted on the intake manifold or firewall. To replace it, first disconnect the negative battery cable, then unplug the electrical connector and remove the mounting screws to take out the old sensor. Install the new sensor in the reverse order, reconnect the electrical connector, and reattach the battery cable. Always consult your vehicle’s service manual for specific instructions related to your Taurus model.
I'm not aware that part was installed on Villagers. It would be on the EGR valve if it was.
its the DPFE sensor....39.99 at autozone....about 20 minutes to replace...
the dpfe is a small metal box on top of and behind the engine. It should be about 3in. wide by 2in. tall by 1in. deep. It has two screws that hold it on on the left and right side. There are two hoses that connect at the bottom of the sensor and one wire harness that plugs in. To replace, simply pull off the hoses and wire harness and unscrew the screws. When replacing, make sure you put the correct hoses in place (one has a smaller hole than the other). It is best to replace with an OEM part, but cheaper plastic ones can be used, although the don't fit very well.
The speedometer is driven by the vehicle speed sensor. See "Related Questions" below for more about where to find it, and how to replace one.

Here's an answer that was posted at Yahoo.Canada by cgriffin: I have to say it is correct for my 2000 Expedition. THANK YOU cgriffin!! It's a code referring to the DPFE sensor. IT could be that one of the hoses are unplugged or broken or plugged or Egr tube coul be damaged. Find your DPFE(about 1" by 3" little box. May be chrome or black plastic in color) To find it follow your exhaust manifold to the two small tubes that have short black hoses attached. These hoses lead(both of them) to the DPFE. I usually go to AutoZone and look at their parts pictures if I am unsure of what the part looks like that is the "evil do-er" on the OBD code.
It is important to keep up with a vehicle, to find out if there are issues a scanner will read codes. The code P1401 means DPFE Sensor Circuit High.
Contact your dealer.
The DPFE (Differential Pressure Feedback EGR) sensor on a 1996 Ford F-150 5.8 is typically located on the passenger side of the engine, near the firewall. It is mounted on the intake manifold and connected to the EGR system. You can usually find it attached to the EGR tube, which leads to the exhaust manifold. To access it, you may need to remove some components for better visibility.
