Regen,soot load,aftertreatment injector issues

[joed2323]

So, removed the differential pressue tubes blew them out, all checked out ok.

Forced regen, soot load was 0.Leaving the yard for a test drive. Soot load started reading .02 then increased up over to 4.oz again. The aftertreatment injector kept turning on then turning off, stayed on for a bit and would shut off, wtf.

Climbed a bunch of hills. Weird thing I noticed was when I.would jake going down hills I noticed the soot load dropping faster when I was jaking then just running full throttle up the hills.


Threw a bunch diff pressure codes. Then the regen light would come on then go off, soot load dropped only to about 3.oz

Why would the aftertreatment injector come on and go off, almost as the it couldnt make up its mind on wtf it shoild do?
