What Causes the ESP Indicator Light to Illuminate?

[JonathanLynn]

ESP light illumination is mostly caused by sensor malfunctions. ESP, commonly referred to as the Electronic Stability Program, indicates a potential fault in the vehicle's electronic stability control system when the dashboard light is on. This requires immediate inspection and repair. The ESP is not an independent system; it shares sensors with other electronic devices like ABS and TCS. If the ESP malfunctions, it may affect other vehicle functions. Additional Information: 1. The ESP system primarily consists of three major components: sensors, actuators, and the electronic control unit. Sensors include wheel speed sensors, lateral acceleration sensors, steering angle sensors, yaw rate sensors, and brake master cylinder pressure sensors. Actuators are typically composed of the braking system and hydraulic modulators. The electronic control system is a crucial component that can intervene and adjust the engine's power output. 2. The ESP system involves numerous sensors, so faults usually originate from sensor issues or loose sensor connections. If the ESP indicator light on the dashboard illuminates while driving, it is essential to reduce speed and avoid excessive steering.
