Cougar/XR7 V8-4.6L VIN W (1997)
Steering Angle Sensor: Description and Operation
An optical steering sensor (photo-cell), mounted on the steering column, is used to establish the rate of the steering wheel rotation.
^
When the steering wheel rotation rate reaches 15 rpm, the output current to the power steering control valve actuator begins to reduce, providing
additional power steering assist.
^
Once the steering wheel rotation rate reaches 100 rpm, the output current to the power steering control valve actuator reaches zero and full power
steering assist is provided.
^
After the steering wheel rotation rate drops below 15 rpm, the output current returns to the amount of current regulated by the vehicle speed
sensor input within one second.
