What is the reason why the EPS light comes on and then goes away after restarting the engine?

If the EPS light comes on and then goes away after restarting the engine, it may be due to a sensor issue. In this case, you can check the vehicle's fault codes. Here is some information about EPS: 1. Definition: EPS refers to the electric power steering system in a car. If the EPS light illuminates on the dashboard while driving, it indicates a malfunction in the power steering system, which requires timely repair. 2. Classification: There are three types of power steering systems: HPS (Hydraulic Power Steering), EHPS (Electro-Hydraulic Power Steering), and EPS (Electric Power Steering). Among these, EPS is the most common type. The electric power steering system only provides power assistance when steering, and notably, the electronic steering system can be adjusted via software, making steering lighter when the car is moving at low speeds.
The EPS light came on but went away after restarting the engine, which is usually the system's response to a temporary malfunction. EPS stands for Electric Power Steering system, which relies on sensors and control modules to function. When there is an instantaneous signal error, the light will illuminate. Restarting the engine is like rebooting a computer, clearing memory errors and restoring the system to normal operation. Common causes include electrical noise interference, dirty or loose vehicle speed sensors, and unstable power supply, such as slightly low battery voltage causing signal fluctuations. This is more likely to happen in humid weather or after driving over bumpy roads. It is advisable to check these areas to prevent recurrence. Ignoring it for a long time may lead to sudden loss of power steering, which is very dangerous. Therefore, when it occurs, don't take it lightly and investigate the root cause. Just have a mechanic use a diagnostic tool to read the fault codes.
The same thing happened to my car last time - the EPS light suddenly came on for no reason, gave me quite a scare! After restarting, the light disappeared, felt like the system just took a nap and woke up. Asked my friends and learned that electronic control systems can sometimes act up - things like dust-covered sensors or loose connectors can trigger false alarms. Proper regular maintenance helps prevent this, like cleaning dust and tightening connections periodically. Restarting works as a temporary fix, but doesn't mean there's no problem, especially for older cars - don't slack on getting it checked at the shop. If the light flashes while driving, it's dangerous as steering may become heavier, increasing accident risks. Get it fixed promptly to avoid stalling midway.
