What causes the power steering light to come on,and why does my power steering keep going out?
power steering on 2005 Saturn Ion
You Saturn uses an electric power steering system as opposed to a more traditional hydraulic system. The power steering light will come on whenever the power steering control module detects a fault with the system. Fault code(s) will be stored in the control module and can be retrieved by the service technician to help isolate to cause of the steering system issue. Turning the key off may clear the light but the problem has not been fixed, when the fault occurs again the light will come back on.
