dpf purge air actuator engine faults

[1mattrichert]

Ill run it in and get it scanned, but the next thing on the list is the air actuator. Ive already had everything else replaced and a seperate issue on top of that which the cummins tech did some investigating and thought it might be, but 5 days later the fault came on again. My concern is getting this air actuator replaced and it turns out I just needed to replace a sensor or 2 this whole time. What their software is telling them is sending them down the list of replacing parts until the problem is solved.
