What does the steering wheel symbol on the dashboard indicate?

When the steering wheel symbol appears on the dashboard, it indicates a malfunction in the vehicle's power steering system, which requires immediate repair. All vehicles are equipped with a power steering system, and there are three common types: electric power steering (EPS), electro-hydraulic power steering (EHPS), and hydraulic power steering (HPS). The electric power steering system does not have hydraulic components and relies directly on an electric motor to provide steering assistance. Both electro-hydraulic and hydraulic power steering systems include hydraulic components and feature a power steering pump. Notably, the electro-hydraulic power steering system does not consume engine power.
I remember that time driving home when suddenly a steering wheel icon popped up on the dashboard, giving me quite a scare. The steering wheel immediately became heavy, making it almost impossible to turn. I quickly slowed down and pulled over, turned off the engine, waited a few minutes, and tried restarting, but the light remained on. After checking online, I learned that this usually indicates a power steering system failure, possibly caused by a sensor malfunction, low battery voltage, or a short circuit. Losing power steering at high speeds can easily lead to loss of control, which is extremely dangerous. I immediately contacted a repair shop, and the technician used a diagnostic computer to identify it as a minor software bug—refreshing the system fixed it. Since then, I've made sure to have professionals inspect the steering components during maintenance to prevent such incidents from happening again.
As a car owner, when I experience the steering wheel warning light illuminating, I understand it indicates an issue with the power steering system. The most common causes are insufficient power supply due to an aging battery or dirty sensors affecting signal transmission. High humidity after rain can also easily cause wiring faults. My approach is to immediately pull over and check: first, listen for any unusual noises when turning the wheel and check if the steering feels heavy. If drivable, maintain low speed and head to the nearest repair shop; if the light stays on, don't take risks. Professional diagnosis can resolve the issue at a reasonable cost. For regular maintenance, keeping the engine bay clean and replacing the battery periodically can effectively prevent similar problems. Safe driving is no small matter—address issues early to avoid bigger troubles.
