    If I were to bet a dollar I'd check your harness. All 3 of them have possible causes being that. Maybe a wire is cut or you have some grounding out next to each other.

    thanks, I found this after hours of looking. Now, I just need to find a detailed photo of said harness/sensor, so I can replace it. Mack is not being very helpful in the matter.

    I figured I'd start with the sensor, and go from there. I just need a picture of where the dang thing is on the truck......don't want to replace the widget, and not the actual kanooder valve....lol

    I am buying a 2011 Mack Pinnacle CSU613 in a few weeks and I'm looking forward to it. How has your been treating you so far??
