New member, have engine light on.

[Bengalcats58]

I have a 2022 Ram 3500 Crew cab HO diesel Used for pulling our 12k Jayco 5er. No issues in 14k miles. Had T43 recall done to install the second particulate matter sensor. Now two months later, solid yellow engine light, code P2002 emission code. No other issues. Health report shows all ok. Presumably coded due to too much short trip driving in sub freezing temps where the truck doesn’t warm up. Code won’t clear with my OBD2 reader. Took a 70 mile trip today, code still there, but now ready to start a regen based on particulate sensor reading. (In 70 miles, particulate matter gauge went from 0% to about 40% full. My truck usually regens at about 45%) Google says most people will get this code a one point, light will eventually go out. Advice?
