EGR Insufficient Flow. Tried searching already.

Car: 2003 Zetec, Automatic
Issue: p0401 code (EGR Insufficient Flow)

After a long time of plucking at this...

I've tried cleaning the valve. It's spotless. I replaced the tube, absolutely free/clear of any buildup. I checked for leaks, none whatsoever. I replaced the DPFE sensor. Could this be it? I got a BWD from Advance Auto Parts when I worked there... Could this be it? I've heard that Foci are pretty picky when it comes to sensors... As far as O2's are concerned, I use strictly NTK's. Could the DPFE be just as "choosy"?
