description A method and article of manufacture are provided to monitor a sensing system operative to monitor electrical current in a transmission line between an electrical storage device and an electrical machine. The sensing system comprises first and second sensors, operative to monitor first and second ranges of electrical current. The method comprises determining outputs of the first and second sensors are valid, and comparing outputs of the first and second sensors when current is substantially zero. The method comprises comparing magnitudes of the outputs of the first and second sensors when the monitored electrical current, and monitoring polarity of each of the outputs of the first and second sensors.
