Steering Angle Sensor: Description and Operation

STEERING WHEEL POSITION SENSOR
The position sensor measures voltage differences to monitor the steering wheel position. The sensor informs the control module whether the steering wheel is being turned left or right and how far it is being turned. The control module passes this information to other modules using the HS-CAN bus. The position sensor is part of the power steering control module and is not serviceable separately.

STEERING SHAFT TORQUE SENSOR
The torque sensor is part of the power steering control module and is not serviceable separately. The steering shaft torque sensor provides direction and steering assist information to the power steering control module. The sensor is a 5-volt dual analog sensor with an output voltage range of 0.25V to 4.75V. With the steering wheel turned to the left, the left signal increases while the right signal decreases. With the steering wheel turned to the right, the right signal increases while the left signal decreases.
