Why Is My Power Steering Warning Light On?
The Power Steering Warning Light means your vehicle has detected a fault in the power steering system. Steering may become significantly heavier, making the vehicle more difficult to control—especially at low speeds.
No OBD scanner required.
Immediate Answer
What Does the Power Steering Warning Light Mean?
The Power Steering Warning Light indicates that your vehicle's power steering system isn't operating correctly. Depending on your vehicle, this could involve the electric power steering (EPS) system or the hydraulic power steering system.
When power steering assistance is reduced or lost, the steering wheel becomes much harder to turn, particularly when parking or driving at low speeds. While the vehicle usually remains controllable, steering effort increases considerably.
Common causes include a low power steering fluid level (on hydraulic systems), a faulty electric steering motor, steering angle sensor issues, or electrical faults.
Is It Safe to Drive?
Can You Drive With the Power Steering Warning Light On?
- Usually yes—but steering may be much heavier.
- If the steering still feels normal, you can usually drive carefully to a repair facility.
- If steering assistance has been reduced, expect the steering wheel to require much more effort, especially during low-speed maneuvers.
- If steering suddenly becomes extremely difficult, locks up, or the warning appears together with multiple electrical warning lights, stop driving when it's safe and have the vehicle inspected.
Avoid unnecessary driving until the cause has been diagnosed.
