I have a 2014 6.7L, both EGR and DPF deleted, but today, out of the blue today, I got a P0472 (Exhaust Pressure Sensor A Circuit Low) and a U029D (Lost Communication with NOX Sensor 'A').
Then the truck went into limp mode, and I had a heck of a time getting home.
Aren't both of the sensors involved in these messages disabled by the tuner?
Hopefully, this is a quick fix; any help is appreciated!
