2015 ram 199,000 p020EE CODE, Urea NH3 level monitoring

[Curt M]

Got the dreaded P020EE code, attached is a copy of the live data, can see , dosing solenoid , tank level and urea NH3 level monitoring, and actuator testing, question i would suspect urea nh3 monitor would a value, but iam not sure if that is the sensor value or what iam looking at, the data was while I was driving the crap out of it, need some help here

Why has there not been any reply???

Do you check your DEF injector for crystallization?

 

[Curt M]

Yes i just checked it again and it was clean, cleaned a a few months ago, how often depending on mileage obviously but what would be youre best guess, from the pic of my scanner, does one indicate no def flow ??

Had tons of issues with this code constantly popping up. Even with dealer replacement of exhaust system, sensors etc. come to find out it was the DEF injection pump was bad, erratic. Once replaced all problems went away. Luckily it was covered under extended warranty. 2016 Ram eco diesel.

Well figured it out, seems the exhaust flange gasket was leaking the exhaust melted the def supply line closed, I never really noticed until I removed the def injector again to double check, I never suspected it cause I had the injector out to clean a month ago so I knew it shouldn't have been to bad and it wasnt
