Got this code 1925 Aftertreatment Fuel Shutoff Valve 1. Does this mean doser injector is bad or fuel shut off valve sensor went bad? I cleaned doser injector about 50k miles ago so maybe it's time for new one?

No sir,
There is a little module on the left rear of the engine,
If you back trace the fuel line from the fuel doser it will lead you right to it
and its a pain to get to,
But there are what looks like 2 sensors that screw in from the bottom the
one closest to the front is the fuel shut off valve
Depending on the truck, its almost easiest to pull the starter to get to it

I just swapped it out $80 for shut off valve. I did forced regen and still throws code 1925. Unilevers says maybe 7th injector or wiring fault. I will try to inspect doser injector tmrw when engine is cold.

I just ran into this on a truck thursday my self
It was throwing the 1925 code and the pressure sensor was bad
Looking at the pressure threw insite with fuel and air pressure bled off it was still showing
86 psi
If you have insite check the pressure
