Hi there,
This question is directed to those with good knowledge of Cummins ISX. Dealing with God #### very frustrating code (Cummins 3225 Aftertreatment purge air actuator - mechanical system not responding or out of adjustment ) or (International 3490 fmi 7, same description )
Truck has 300k mostly original parts wise, except for new Aftertreatment air purge valve and aftertreatment fuel doser valve/injector.
Truck does regen fine, heats up to 1040 degrees and completes the regen. When code is deleted and we run the regen everything looks fine until ECM switches from aftertreatment injector status Not dosing to Dosing. It throws Cel immediately upon switch sequence.
What else can be checked though? Shop reported purple air line not leaking, I'm currently out of ideas so if you know something more and don't mind to share, I'd appreciate your help.

Does the code clear after the truck runs down the road for awhile?
Is it derating? -
Don't worry my friend. Problem is the fuel doser manifold #5308313. It is leaking internal. Have gone through this more than a few times. Trust me on this one....

Remove inner fender. Find something soft to kneel on for a while. Hopefully your hands are small. Spray fitting that fuel line screws into with PB blast. IIRC you did a wonderful job with Maxforce manifold replacement? This is a piece of cake compared to that.
