Broke down yet again

[trdodd07]

Got the truck into the shop now. I pulled the fault codes before it rolled in. Before, the NOX issues were that the conversion rate was low, and now this time it's about an abnormal update rate.

Cummins codes are:
2771 Aftertreatment 1 Outlet NOx Sensor - Abnormal Update Rate
3717 Engine Protection Torque Derate - Condition Exists

I surely hope that is not the issue. I looked underneath a few days ago because I had to replace a v clamp that they stripped out. I didn't see anything abnormal but after reading that post, I'm gonna take a good look up it's skirt now.
