my check engine light is on (2001 4.0L V6), so i went to autozone to get the code read. turns out it is p0401 for insufficient egr flow. after doing some searching on the forum and online, i have decided to replace the differential pressure feedback EGR sensor (DPFE). i went to swap it out today, but want to make sure i am pulling the right thing out. it this is? if so, i tried pulling it out but it doesnt seem to want to budge. any thoughts? thanks in advance for any help!

Thats It! Mine Went Out At About 60,000.

ok thanks, that's what i thought. should it just pull off the hoses once i un-plug it?

got it off today. CEL is still on, but i only took it around the block once. i'll update tomorrow after a day of driving.

did you unhook your battery to reset the computer

i didn't but i will. thanks!

if your cel come back on with the same code, take your egr valve off and make sure the passage for the egr isnt clogged with carbon. i get that a lot...

unplugged the battery yesterday, and CEL is now off. replacing the DPFE seems to have corrected the problem. thanks for the help!
