WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 GMC Yukon XL, 2003 GMC Yukon, 2003 Chevrolet Tahoe, 2003 Chevrolet Suburban, and 2003 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

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.
