What does PS mean in a car?

[GemmaLee]

In a car, PS refers to the power steering system. When the PS indicator light comes on, it indicates a fault in the power steering system. The PS display on the car dashboard is a steering wheel lock indicator. After starting the car, the steering wheel lock light disappears. If the PS light is on and the key cannot be turned when inserted, you need to wiggle the steering wheel left and right. Once the light goes off, the key can be turned, and the vehicle can start normally. The steering wheel lock is a basic anti-theft feature of the car. Its working principle is: through the rotation of the key, a steel pin is controlled by a spring. When the key is pulled out, if the steering wheel is turned, the steel pin will pop into a pre-drilled hole, then lock the steering wheel to ensure it cannot be turned.
