I have a 2002 Explorer with 103K miles. Had a P0401 EGR valve low flow. Changed the EGR valve and still got the Engine Light to come on. I reset the light and it came back on after a few miles. Do I need to change the DPFE sensor as well? Please help?

First, wrong section. Second, DPFE sensor is the most common failure.

had the same code, it was the flow sensor, also had it happen right after and turns out clogged cats back pressured to much messing with them, just cut the cats off and put a dual flowmaster set up under it :)

Hmm I just got a P0401 code. After searching around I think I am going to go with the DPFE sensor first. My truck has 51,000 miles.

The 02 Explorers fuel filter is built into the fuel pump--it needs to be brought into Ford to be serviced. I think mine needs the same thing after all the 1200.00dollars I put into it since I bought it in May-08--Crappy Feeling huh!

Oh yeah and theres no DPFE fuse on these trucks
