Abstract
A system for powering a steering angle sensor coupled to a steering wheel and a controller comprising a switch, coupled to the sensor and the controller. The switch is activated upon motion of the steering wheel or steering shaft. The switch, when activated, connects a power supply, such as a vehicle battery, to the sensor and the controller so that a new steering angle may be sensed and stored. After a predetermined period of time, the controller sends a signal to deactivate the switch and disconnect the power supply.
