Nice description of testing this. And I haven't done it yet, but the problem I have from my thread here is that I am getting a code of C1225 Excessive LF Wheel Acceleration. So my wheel speed sensor is working fine (I assume), just reading faster than the other wheels. So I am assuming that a new hub will fix this, but I have no idea...any help?
Well, I'm not 100% sure on this one but... I do know that it is possible for wheel speed sensor to also read an unusually high amount of resistance when it goes bad. Also, like I mentioned before, the resistance should fluctuate up and down on a good sensor. If a wire or circuit comes apart internally, it will read as an open circuit, so I'm not taking that into consideration here. So, if the resistance reads unusually high or the sensor "sticks" at the high reistance side of it's fluctuation, then I suppose the car could interpret that high or constant resistance as the wheel is still turning at a high rate of speed. It would think the teeth on the internal wheel were still passing the magnet at a high velocity causing the more constant resistance.

This of course, is completely a guess.
