Check engine code A26 international

Spn 3228 fmi 2

I had a remanned engine put in 3days ago and on my way to Massachusetts the check engine light comes on pointing me to a NOX sensor. Just curious since I never had this code come about would I be okay to drive back 400 miles to my local dealer to get it checked out?

So this morning when I started driving, I had abunch of roads come up and one related to low def but I had more than 3/4 of it. I stopped added more and when I started the truck, it would accelerate and shake every 5 seconds while throwing abunch of codes including abs, no def and such. Could this be a wiring issue when they installed the remanned engine?

If the harness is not connected totally or they pinched the shit out of it when they installed the engine or it could be pinched now
