What does it mean when the EPS light on the car is on?

When the EPS light on the car is on, it indicates a chassis braking technology developed on the basis of the anti-lock braking system (ABS). It mainly consists of a control unit, steering sensor, wheel speed sensor, slip angle sensor, lateral acceleration sensor, and other components. EPS enables automatic vehicle safety control, effectively improving driving stability and safety under dynamic conditions such as braking, acceleration, and steering. The EPS system includes various sensors that comprehensively detect the vehicle's driving state, as well as an intelligent onboard microcomputer control system for analyzing and processing signals from these sensors. The sensors used in the EPS system include the yaw rate sensor, lateral acceleration sensor, steering wheel angle sensor, brake pressure sensor, and throttle position sensor, all of which are essential components of the system.
I think the EPS warning light is a pretty serious matter. When that yellow light pops up, it means there's an issue with your car's Electric Power Steering system. You'll definitely notice the steering wheel becoming extremely heavy while driving, especially when making turns or U-turns. Last week, my neighbor's 80,000-km old Civic had this exact problem - turned out the torque sensor in the steering gear was clogged with sludge, and it worked fine after cleaning. If your steering wheel suddenly becomes brick-heavy when stopping at red lights, don't force it. Pull over immediately to check for loose battery connections. This isn't something to delay - I recommend contacting a repair shop right away to read the fault codes. A minor issue might just need code clearing, but if the motor's burnt out, you could be looking at thousands to replace the entire system.
