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
Customer reply replied 1 year ago
Aftertreatment Fuel Shutoff Valve 1 - Data Erratic, Intermittent, or Incorrect. An error has been detected in the aftertreatment fuel shutoff valve or the aftertreatment fuel injector system.

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

I replaced the doser valve already. Is the shut off valve located in the fuel manifold ?
