Inactive Doser Valve

[kozakvod]

Coming south on I25 today 30 miles north of NM state line:

Red solid light on DEF gauge
Check engine amber.

Stopped hooked up insite 3567 code: DEF Doser Valve - Current below normal or open circuit

Nothing I could do other than go with it (Yes I knew what was going on, but 200 miles from Denver, Albq and Amarillo I was heading home to Dallas so Amarillo the choice) I get just outside of Raton, Engine Derate code. I was empty so I never really noticed the derate. I got to Amarillo and the solid red light on the DEF gauge began flashing. I made it to the Petro parked in fuel island and while getting fuel and red stop engine light full derate code 3712 SCR operator Inducement - Data Valid but above normal operational range - most severe level.

My truck is a 2014 Pete 388; Engine 2013 ISX15, 2350.

The dose valve was replaced at 501,841 12-28-18; current OD: 581,090.

I'm currently sitting (I did manage to get parked) at the Petro.

Any help suggestions etc would be most appreciated..
