The Electric Belt Drive Rack and Pinion Steering Gear contains the steering wheel angle sensor. The steering wheel angle sensor identifies the position and direction of the steering wheel rotation to calculate the driver intended driving direction. The power steering control module uses the signal to determine the proper amount of steering assist to provide.
