Why is the tire pressure yellow light on?
1 Answers
The tire pressure yellow light indicates that the pressure in one of the vehicle's tires is insufficient and requires immediate inflation. Once the tire pressure reaches the normal value, the yellow light will automatically turn off. Tire pressure monitoring light on: The tire pressure monitoring indicator is a yellow symbol, resembling an irregular circle with no seal on top, four small spikes at the bottom, and an exclamation mark inside. The illumination of this light indicates abnormal tire pressure. Abnormal tire pressure generally occurs due to the following three reasons: Abnormal tire pressure: Typically, an alarm is triggered when the pressure is below 1.8 bar or exceeds 3.0 bar. In such cases, tire inspection and pressure adjustment are necessary. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure monitoring system is not reset promptly, it continues to record the previous data, causing the tire pressure monitoring light to stay on. Simply resetting the tire pressure will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, installed inside the tire and connected to the inflation valve, monitors the tire pressure. If the sensor is damaged during driving, the tire pressure warning light will illuminate. In such cases, the only solution is to replace the sensor with a new one.
