sensor problems, help?

Ok guys, so randomly all 3 sensors quit on me and I'm kind of out of ideas here. I have a custom harness and all three (CLT temp, IAT & CAS) are all gounded on the big pin plug on the board.

At first I thought that something must have happend to the common ground since they all quit at the same time, but each of the three sensors has a ground (checked with an ohm meter individually). Both the IAT and CLT show -40F, and I also tryed shorting them to see if they would go to max hot, and they don't move at all.
So, its NOT the gound, they all have ground, its not the senser (I tryed shorting them and tested the sensor resisatances)
And the CAS shows closed most of the time, but pulses (as shown on an ohm meter while manually turning the motor by hand).

Does anyone have any ideas as to why all 3 quit at the same time?
