p0401 code back on after 8 months - lot of discussion on cleaning TB ports and intake ports. TB was clean but confused on where are the EGR ports located on manifold - do you have to pull it to clean ? Any info or pics would be helpful.
On my snap-on scanner the possible causes strongly looks to the DPFE sensor as the cause. Might want to replace it. I know Ford has up-dated this part because of the problems with the original sensors & there is a TSB out for this issue (TSB 04-11-01). You might want to look into it.
Changed out the DPFE ~ Sept 07 with one purchased from Pep Boys - cleared code - lasted about 7 mths.

Live in Tx where heat can be an issue under the hood.
Just want to verify that EGR ports are clean - when I cleaned TB didn't notice anything plugged but that was the TB stand alone.
Has about 75K miles on it.
Thanks for responding TK -
