I replaced the Doser injector about 40k ago because I was replacing my thermostat at the same time. I have not cleaned the dozer since.

DPF Delta-P? -- Clean/replae the SCR Filter? clean out the SCR injection crosspipe?

Lots of maintenance on those CM2250's.

I have not replaced/cleaned any other sensors. I plan on doing that very soon as the weather up here in NH is getting better. What is the SCR injection crosspipe? And also I was curious if I should replace the DEF dozer as well? I don't know if those are prone to failing/clogging like the DPF dozer.
