OBD code P2201- anyone besides me?
I have a 2014 Ram 3500 6.7 diesel and I get occasional OBD code P2201. It's for "NOx Sensor Circuit Range/Performance Bank 1". Normally all you see is the check engine light with no performance issues. The last time I got it was after we had been using the truck around town. I drove about 7000 miles pulling the Monty mostly and the code went away. When we got home I did the normal 67,000 mile maintenance including the EGR valve and cooler cleaning and a month later the P2201 came back.
The dealer's tech advisor says to drive it hard like I did on my last trip and see if it goes away again. I won't be travel with the RV until spring. So a number of months with the code. It's sounds easy to fix from the Youtube videos, but the part is expensive. Also not sure that is guaranteed to be the fix.
Anybody had this problem?
