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!
