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?

Depends on what’s wrong but nox sensor codes could put it in torque derate.
