Eliminating water from reaching the DPFE Sensor

If they were there would be a fuel in oil recall and a bed side too tall tsb.

Are we talking about the same Ford Corp???

Recall king of 2025? Then yes

Looks like a solution born from pain meds lol. Replacement sensors are cheap enough. An inline filter might work for an air compressor. Not the paper ones, the ones that look like a pumice stone.

That's the thing. I replaced mine a month ago and if I only have to spend $27 at Rock Auto every 98,000 miles then there's not much point getting fancy with it.

Agreed. Better than the time and money in a garage science experiment IMO

Interesting twist to this is Ford tech line is now telling techs to replace the egr tube with egr sensors for surging/bucking complaints before transmission repairs, finding condensation in egr tube giving part throttle misfires without code

Since I have never found a detailed pic of the EGR Tube Assy, I threw this together and (THINK) this may be why. IDK just playing with thoughts of operation as it has been asked more than once for repetitive issues after DPFE (Only) replacement, my thoughts have been the MAPT or this tube, but it does require a Live Data view to truly see what is happening.
I don't like Shot-Gunning parts but I have the proper tools to diagnose, most on here do not and only have Forscan, which lacks in this area.

So at this point - if Ford SSM ? (I believe) where the info came from then it appears they are finding a considerable amount of come backs with only the sensor replacement and a cobo of both is fixing the issue.

I am highly curios to see a cut open view of a (2.3 Tube), I know my past experience the carbon is very hard and hard to get broke down to remove it.

Side Note and a refresher: To understand the Tie in, Transmission (Shift Points) one input for that is engine load, One input of engine load comes from the MAPT sensor, when EGR is flowing the MAPT is seeing that flow, so if EGR is flowing at a greater amount than needed the shift points will also be thrown off.

I think that MAYBE Ford is watching this Forum...

Yes, I believe they are and I think MAYBE the website issues we’ve been experiencing are denial of service attacks initiated by Ford.

Been thinking the same as for a filter of some sort inline. Kind of felt like if I did put some kind of filtration that it would affect the pressure readings, but I don't know. Everyone is obsessed with moisture in the system, when I replaced my sensor the third time I replaced the EGR tube as well. What i noticed is a lot of oil and a coked up tube. I didn't see any moisture. My thought it was oil that was fouling up the sensor not moisture. Who knows. just stating what I saw in my system.

I recall Ford making a big deal out of their improved EGR system, to me same old problem prone EGR as yesterday's EGR except that it's become more expensive to fix now and harder to troubleshoot. And of course it's only warranted for 2 yrs. now.

I wonder how Ford bypassed the 5 year emission warranty. EGR is certainly part of the emission system.

Clean air act decades back reduced the Federal emission warranty on minor emission parts to 2yr/24k miles. Some states have longer coverage, CA comes to mind.

They've (EGR systems) been around since the smog pump era of the late 1960s / early 1970s. By 1973 all US Made autos were gas hog dogs. Slow and thirsty! Got somewhat better in the 80's, but still bad. All an EGR system does is destroy efficient/optimal combustion to lower combustion temps to prevent NOX creation. It's been a 50+ year curse on autos.

Clean air act was put in place in 1968. Maybe amended later??? Guess I need to keep up with current events...

IIRC it was in modified in the 90s , back in the early yrs of egr you could simply disable the EGR system with no noticeable effects - in fact disabling would allow many engines to run better. Should emission requirements be lessened it's possible egr systems may no longer be needed, some engines don't need them and rely on variable valve technology.
