Engine derate in 3 hrs, seek service immediately!

I have a 2016 KW T880 with 93k miles on ISX15 450hp
I just got this message yesterday and it’s got me all panicked. I’m new to all this new emission system BS, but thanks to CA I had to get rid of my older, perfect running trucks, and put myself in debt on a newer one! I run local dirt, just a ten wheeler, not even any freeway driving. So I know it’s probably not great for dpf but I do a forced regen every couple of weeks. The message came on and stayed on for a little while. Then went off. I parked up for day and ran today but no message. I’m still very nervous. Any tips, ideas? also, someone said I might need my dpf baked. Even at 93k miles???
Any help appreciated

 

But it ran today with no message, no check engine light. Could it be possible that a sensor just picked up an odd reading and threw that sign, then corrected itself?i guess that is what I’m hoping

 

The mobile mechanic I use can only get to me Friday so I’ll try run again today and hope nothing springs up. I’ll see if there’s any logged codes and go from there.

 

This is what codes came up, and a log of parameters, anybody familiar with these?

 

Thanks, I’ll dontyat

 

Replaced the sensor, checked the dpf pipes for soot accumulation which was none. Ran the truck today with a few loads and same derate message just came on and now CEL illuminated. This is killing me.
