What does it mean when the ESP light comes on in a car?

The illumination of the ESP light in a car indicates that there may be a malfunction in the Electronic Stability Program system. Since ESP is not an independent system, it typically shares sensors with other electronic devices such as ABS and TCS. It could also be caused by damage to other functions. In such cases, it is recommended to send the vehicle to a 4S shop for inspection as soon as possible. ESP, also known as Electronic Stability Program, analyzes the vehicle's driving state information transmitted from various sensors and then sends correction instructions to systems like ABS and EBD to help maintain dynamic balance. ESP can keep the vehicle in optimal stability under various conditions, with more noticeable effects in cases of oversteering or understeering.
That day when I was driving home, the ESP light suddenly came on. As an experienced driver, I immediately pulled over to check. The electronic stability program light usually indicates an issue with the vehicle's stability system. Possible causes include a dirty or faulty wheel speed sensor, a malfunctioning steering angle sensor, or similar problems. That time, I encountered mud on the sensor, and the light went off after cleaning it. It could also be due to low battery voltage affecting the system or a faulty control module. When ESP fails, the car is prone to skidding in rainy or snowy conditions, which is very dangerous. It's advisable not to force the drive; instead, use an OBD scanner to read the fault codes, identify the root cause, and then take it to a repair shop. Regularly cleaning the sensors during maintenance can help reduce such faults.
