The steering wheel position sensor is a 0-5 volt device which is used to sense steering wheel position and turning speed. The valid signal voltage range of the sensor is 0.35-4.75 volts. The signal voltage will increase or decrease within the valid voltage range as the steering wheel is turned. The body control module (BCM) monitors the steering wheel position sensor signal voltage and transmits this data on the serial data line.
