You should have had plenty of less severe warnings long before you get to that point. Regardless you may want to check the electrical connections, clean up any corrosion, make sure no loose or broken wires and check all your vehicle grounds.

Not sure the engine but its a 2012 peterbilt red cummins

Driver woke up to a red regen light (couldnt force regen). Called company who regened truck but computer is saying the NOx sendor is bad. Mechanic said he can try to clean it out but it womt last but a few minutes before it breaks down again.
