From what i have seen the single house units rarely fail and 90% of the time when a code pops up for PFE sensor its due to the EGR passages being plugged, and even after a cleaning of the EGR passages the check engine light might flicker for a week or so before it stops. Now the two hose DPFE sensors are problematic due to their aluminum case that corrodes on the inside. The update DPFE are made out of plastic.

Even after it tells ya you still have to find it or try to find it.

Worked right up to the time I left and couldnt replace the part so
instead of mounting the part back where it was I just connected it and let it hang there with the EGR vaccuum switch necause i planned on fixing it here in Tenn.

Funny thing happened on the way here. On the way here the engine light came on as expected but went off after a few minutes then it didnt come on at all and I thought it was burned out. (check engine light) It wasnt and when I ran a self test 111 code came up

I read in some other posts that some Ford vehicles go through them pretty regular. Some have been relocated to the fender or fire wall wall also.

Thought it was to make it easier to get too the next time.

I believe it is heat from the manifold that causes the problem

Perhaps going from hot to cold in winter causes condensation to form and shorts them out I dont know but one thing for certain is its not going back where it was if it gets replaced at all. Seems to be working . Had some nice long accelerarions up these mountains and no light.

If it ends up wotking out without replacing thats a 100 dollar swing. The
70 I dont have to pay for the wrong one and the 30 or so not paid to replace
the right one
