Claim 6:
7. The system of claim 3, the reference circuit further comprising a second envelope detector that receives the output of the second series RC network and provides an output representing the amplitude of the output of the second series RC network, and the microcontroller comprising:
an analog-to-digital converter that produces a first digital signal representing the amplitude of the first series RC network from the output of the first envelope detector and a second digital signal representing the amplitude of the second series RC network from the output of the second envelope detector; and
first decision logic that determines if the sensor assembly is operating within specification from the second digital signal; and
second decision logic that determines if water is present within the electronic power steering assembly when the sensor assembly is operating within specification.
