jkisul Posted April 26, 2023 Share Posted April 26, 2023 I have a 2018 mack mru with the mp7. I have that code number referring to regeneration incomplete- active I'm using j-pro and when I'm in the Regen screen all the emissions are n/a def tank and level work tho. I can unplug a sense and it reads that it's Shorterd/open circuit so do I check the can wiring side?
