    Measure resistance for breakage in wires, measure volts for distance from sensor to abs ring, check if any points out. Dont remember if ac or dc, but thats where i failed. Measure voltage while spinning wheel.

      resistance is static measure (if sensor is good or bad) and voltage is dynamic (if sensor react on wheel spin) . U havent any numbers while voltage measuring? Or just too different ?
