What does it mean when the power steering warning light is on?

Power steering warning light may indicate a steering system malfunction. Here is a detailed introduction to automotive steering systems: 1. Components: The automotive steering system mainly consists of steering wheel assembly, steering column assembly, rack-and-pinion power steering gear and tie rod assembly, power steering (hydraulic or electric) system, and wheel assembly. 2. Function: During driving, the vehicle needs to frequently change its direction according to the driver's intention, which is called vehicle steering. For wheeled vehicles, the method to achieve steering is that the driver uses a specialized mechanism to make the wheels (steering wheels) on the steering axle (usually the front axle) deflect a certain angle relative to the vehicle's longitudinal axis.
I've been driving for twenty years, and the power steering warning light coming on is all too common. Most of the time, it's due to an issue with the steering assist system, like a faulty electric power steering module or a sensor malfunction. When the light comes on, the steering wheel becomes stiff while driving, making turns particularly difficult—even parking maneuvers can become hazardous. My old car had this exact problem. The first thing I'd do is check if any fuses are blown or if the battery is dead—common issues with electric power steering systems. Ignoring it not only makes driving uncomfortable but can also damage steering components, leading to more expensive repairs. I always drive straight to a nearby repair shop to have a mechanic use a diagnostic tool to read the fault codes and identify the root cause. For routine maintenance, I make sure to check the power steering fluid level during regular servicing, as low fluid in hydraulic systems can also trigger the warning light. A little prevention goes a long way.
