Circuit Description
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The electric power steering (EPS) system uses a torque sensor to detect the amount of torque being applied to the steering column shaft when the steering wheel is turned. The power steering control module (PSCM) uses this sensor as the main input in determining the amount of steering assist needed.
