Ok Im replacing the rear axle assembly in a couple weeks, its parked until then.
When thats done Ill go to one nearby and try my luck.

If I wanted to bench test the wheel sensors in the meantime, any suggestion how Id go about that?

 

The only thing you can measure is continuity. It will be either open or closed.


A good scan tool or graphing meter can provide the info you would need to determine which wheel , if it is a wheel sensor, is causing the problem. Once that is determined, you would concentrate your efforts on that area.
