so what I would do is a stationary regen. If you don't have the capability, then the other option is to drive to until it completely does the regen.
It is going to take several miles.
It would appear to me you either do a lot of idling or just in town start and stop with no real chance for the truck to go through the cleaning cycle.
Other option and it may boil down to it is the dealership; they will do a diagnostic and a stationary regen and it may or may not be determined that the DPF is full.
Very few if any DPFs become full but several get in your circumstances because the emissions systems are something that everyone should be aware of before purchase.
What are your driving habits? Lots of stop and go? Town driving?
If so get it out on the interstate lock out 6th gear and set the cruise
at 70 mph for 30 miles.
98% of my driving is in town, I'm a local contractor that rarely has a chance to get out on a HI way for any extended period of time. I have taken it out on 3 long drives of about an hour each time and running at 70 mph, it didn't change anything. It will not let me do a manual regeneration. I have Forscan and have enabled it but it still will not let me do it. Now the wrench screen has started to show up daily as well.
In Forscan it shows that the
you need a manual regen and consider a gas motor truck for your use, imho.
Emission systems like heat and you have none. If you have a trailer hook it up and do the drive.
If you have the ability to read live data watch EGT 11 and 14. 14 being after the DPF. That will tell you if you are getting hot enough to burn the soot during the regen.

you are only showing 15% soot load in that screen shot.
there shouldn't be a drive to clean message.
I have been locking out 5th and 6th gear and sometime 4th to keep the RPMs up to see if this helps but so far nothing has changed
I used to do regens in 5th gear with 6th locked out. Not anymore. It used more fuel and slightly lower miles to do it so now I just do them in 6th gear... I believe we all started to think that it was optimum for the engine to be at 2k rpm like it is during an OCR or manual regen. But IMO that's just to keep things cool when the truck's not moving...

Good eye... And point. Something going on... Faulty sensor in the DPF?

That could explain why even though this has been going on daily for weeks, it never goes into a derate. If it was a full DPF that will not clean it would almost render the truck useless till resolved.
Problem finally solved. My DEF tank was 1/2 full so I thought that couldn't be the problem, but after trying to figure this out for a month or so I finally read that filling up the DEF tank could help. I filled it up and the messages went away and have not returned. So apparently a 1/2 full DEF tank can somehow cause issues.
Glad you got it resolved. The system was confused and time and travel and then a complete fill fixed it.
IMHO, since dealing with the DEF systems since 2013, If it is run down to <200 miles to empty and then a complete fill the system responds better and does not get confused.
Best advice I can give is to also you the ford fill spout that can be purchased online or at a ford dealer. The spout will make a firm connection at the fill port and not leak as you pour.
More importantly it will not let you overfill, thus preventing an issue during freezing temps.
Overfilled def tanks during freezing temps can be a problem for the tank.
