What does it mean when the PS light in a car is on?

When the PS light in a car is on, it indicates that the steering wheel is locked, and the light will disappear after starting the car. Method to release the steering wheel lock: 1. Insert the key; 2. Turn both the steering wheel and the key in the same direction simultaneously; 3. If the lock is not successfully released, gently turn the steering wheel left and right until the key can be turned smoothly, thus unlocking it. The steering wheel is a wheel-shaped device used to control the direction of cars, ships, airplanes, etc. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft. It mainly consists of a frame, foam, and mounting clips or screw holes corresponding to the driver's airbag (DAB).
Last time I was driving, the PS light suddenly came on, and the steering wheel became extremely heavy, like moving a rock. At first, I thought it was a battery issue, but upon checking, I found the power steering fluid level was too low. The PS light refers to the Power Steering system fault warning light, which normally helps make steering the wheel very light. When the light is on, driving becomes particularly strenuous, especially during turns or parking, which can be dangerous. Possible causes include insufficient power steering fluid, a damaged steering pump, or sensor issues. To address it, first pull over to a safe spot, open the hood, and check the power steering fluid reservoir. If the fluid is low, top it up with the appropriate power steering fluid to see if that resolves the issue. If the light remains on, don’t hesitate—head to a repair shop immediately. After I added fluid, the light went off, but I’ve heard some friends ignored the problem, leading to higher repair costs later.
As someone with some knowledge about cars, I consider the PS warning light to be a critical alert indicating a power steering system malfunction. Power steering assists drivers in effortlessly controlling the steering wheel, and when the light is on, steering becomes heavier, increasing the risk of accidents. Common causes typically fall into a few categories: first, low power steering fluid level—check if the reservoir level is above the minimum mark; second, a faulty steering pump, loose belt, or system oil leak; sometimes, it's a sensor false alarm, especially in older cars with aging wiring prone to errors. It's advisable to stop the vehicle immediately, check the power steering fluid level, and try topping it up. If the light remains on or there are unusual noises, it may indicate a mechanical issue requiring professional repair. Regular maintenance should include frequent fluid level checks to prevent minor issues from escalating. I've noticed this malfunction occurs more frequently in cold weather or after long-distance driving—prevention is better than cure, after all.
