What are the reasons for the ESP fault warning light to illuminate?
1 Answers
ESP fault warning light to illuminate are: 1. Poor combustion state, engine knocking; 2. Internal reasons such as poor fuel quality, unclean engine cylinder interior, and accumulated carbon deposits; 3. Problems with the ESP system; 4. Faulty wheel speed sensor. The wheel speed sensor obtains the wheel speed value through induction and feeds it back to the vehicle computer. Each wheel has an independent wheel speed sensor, and this wheel speed signal is very important. For example, some Volkswagen models are equipped with tire pressure monitoring, but there are no sensors inside the wheels. The tire pressure is determined by comparing the wheel speed through the wheel speed sensor signal.
