What does EPS displayed in the car mean?
2 Answers
When EPS is displayed in the car, it indicates that the electronic stability system has malfunctioned or been turned off. The full English name of EPS is Electronic-Power-Steering, which refers to electronic power steering. It uses the power generated by an electric motor to assist the driver in power steering. Here is some relevant information about EPS: 1. The composition of EPS: Although the structural components may vary among different vehicles, they are generally similar. It typically consists of a torque (steering) sensor, electronic control unit, electric motor, reducer, mechanical steering gear, and battery power source. 2. When a car is in motion, it is subjected to lateral and longitudinal forces. If the lateral force is too great, the steering force can be significantly reduced, making it easy to lose control. EPS improves this situation by independently braking each wheel and managing the engine system based on CPU calculations when the vehicle shows signs of instability, ensuring driving safety.
I've been driving for most of my life, and when the EPS light comes on, it usually indicates a fault in the Electric Power Steering system. This system is responsible for making steering the wheel easier, especially at low speeds like when parking or turning. When the light comes on, the most common causes are sensor failures, such as a damaged torque sensor, or low battery voltage affecting the system's power supply. Sometimes cold weather can temporarily interfere with it. If I see this light upon starting the car, I first try restarting the vehicle a few times to see if it can pass the self-check. If the light remains on, it's essential to take the car to a repair shop immediately—don't wait until the steering becomes heavy and harder to control, as this increases the risk of an accident. During regular maintenance, I also remind the technician to check the EPS-related wiring connections to prevent loose connections from triggering false alarms. Remember, safety always comes first—don’t ignore these warning signals just to save money.
