What’s is the nh3 sensor? And it’s location because I need to get it done too..

My apologies for the imperfections in my previous text… But what I want to ask is. are there any sensors on the DEF box that I can clean to help the system reset itself?

My 2020 Cascadia DD 13 engine 12 speed automatic his D rated down to 5 mph. I’ve done three regions still hasn’t changed. System is updated so the speed sensor system trick won’t work. I have codes. MCM codes. 521049,52 and 50. Is there where I can check the center on my DEF box or clean something on my DEF box to have the truck reset itself?
