What is an ESP system malfunction?

ESP stands for Electronic-Stability-Program, which is the vehicle stability control system. If the ESP malfunction indicator light on the dashboard remains illuminated after the car starts, it is possible that the vehicle's ESP system has malfunctioned. Here is relevant information about ESP: 1. Introduction: It analyzes the vehicle's driving state information received from various sensors and then sends correction commands to systems like ABS and EBD to help the vehicle maintain dynamic balance. ESP can keep the vehicle in optimal stability under various conditions, with particularly noticeable effects in cases of oversteering or understeering. 2. Function: It is a general term for systems or programs designed to enhance the vehicle's handling performance while effectively preventing loss of control when the car reaches its dynamic limits. The electronic stability program can improve the vehicle's safety and handling.
Last week, the ESP warning light suddenly came on in my old car, which scared me so much that I immediately pulled over. ESP stands for Electronic Stability Program, which helps prevent skidding while driving. Common issues that trigger it could be a wheel speed sensor clogged with mud, an inaccurate steering angle sensor, or a malfunctioning control module in the brake system. I remember one time when I was driving in the rain, the steering wheel suddenly felt light and the tires seemed to have no grip, like stepping on cotton—classic symptoms of ESP failure. If this happens, don’t panic. First, drive to a dry area, turn off the engine, and restart it. If the light stays on, you’ll need to check the fault codes. Oh, and when washing your car, avoid blasting the wheel hubs with a high-pressure water gun—the sensors are particularly vulnerable to water damage. Replacing this small part is actually quite cheap, costing just a couple hundred yuan.
I noticed many drivers don't realize that the yellow skid control light indicates an ESP malfunction. This system relies on four wheel speed sensors to monitor traction in real-time. When it detects wheel spin, it automatically brakes specific wheels to stabilize the vehicle. The most common cause is a faulty wheel speed sensor, though excessive mud buildup can also interfere with signals. Last time after off-road driving, this warning light appeared on my dashboard - I fixed it by cleaning metal shavings behind the wheel hub with a toothbrush. However, if the light flickers during bumps, it likely indicates short-circuited sensor wiring due to insulation damage, which requires immediate attention. Modern vehicles can display which specific wheel sensor is malfunctioning on the infotainment screen. When inspecting, pay special attention to potential wiring damage on the tire's inner side caused by road debris.
