Less then 6 months ago the check engine light came on in my 2015 Tiffin( it has an engine listed in the current Cummings SCR recall). I took the rig to the local Cummings service center and they plugged it into the computer. The check engine light and subsequent computer read out said the Nox sensor needed to be replaced.
It cost me $1100.00 to have the sensor replaced. It was 2 weeks past the emission parts replacement deadline. Could the problems associated with the recall have been the reason for the Nox sensor failing?
