2012 peterbilt 386 isx Cummins cm 2250 regen issues - Yc123 - 11-13-2016
Hello everyone
I have 2012 peterbilt 386 Cummins cm 2250. I been having issues with dpf system.
I have alr day replaced the dpf filter. And put new egr valve in today but I am still having problems with this system. Truck keeps asking for regen even when I just started doing force regen thru insite. Regen doesn't complete on it own and had regen going for almost 2 hours so I stopped it my self. Any ideas what I should do now. I can't do @m*m^2 yet. That is my last option

Who did DPF replace? Did they reset DPF?

Check the Delta-P sensor and the tubes for it. the bushings like to crack and give false alarms and regen problems.
Also, make sure you do not have the temp sensors w=swapped.. it is possible for this to happen on some trucks.
Inlet temp should start out higher than outlet temp after Doser fires,.. and it will be the t=other way around after everything gets above 1000 degrees. the outlet should be slightly high after while.
Also, snailexpress has a good point too,.. any time you replace DPF, you have to tell the ecm you did this with a DPF replacement procedure,.. or it will complain.
