What do you think might be happening
Expert:  Bradley Martin replied 1 year ago.

You have to have cummins software to properly regen if that code comes up here is a video about the issue you are having https://www.youtube.com/watch?v=85olDC6qhw0

Customer: replied 1 year ago.
I don't have Cummins insite. So the issue for that code is the turbo actuator? Because the prolink ultra that I plug into it says it's the after treatment

Ok I dont have the cummins software which you will need to diagnose your issue. Were you able to view the video?

Customer: replied 1 year ago.
I did watched the video but that explains how to recalibrate the turbo actuator, my issue is with the after treatment. The code is spn 3482 fmi 2

This is either a sensor or harness problem giving false readings or a problem with your doser/ shutoff valve. Let me know

Customer: replied 1 year ago.
I replaced the doser valve already. Is the shut off valve located in the fuel manifold ?
Expert:  Daniel Wilson replied 1 year ago.

Whats the complete model and serial number of your engine? at least the full model
