Not sure what that means. But with that note, I would double check all the wiring. I would make sure the connections are clean and good. Maybe clean them with electrical cleaner or something. Also, something else I did was check the resistance of each sensor and wires. All were about the same ~1050 ohms. But check yours and see if you get similar readings. Most of the time, from what I know, replacing the entire hub will take care of the problem.
