What does it mean when the tire pressure light is flashing?

The reasons why the tire pressure light is flashing: The tire pressure monitoring light comes on due to a punctured tire. This situation usually involves a very slow air leak, which can be measured with a tire pressure gauge. Tire pressure is too high. Driving with low tire pressure for too long. This usually occurs when the pressure in one tire is too low, and high-speed driving increases the tire temperature, causing the pressure to rise. In this case, you need to stop and rest or replace the spare tire promptly. Abnormal tire pressure generally has the following 3 causes: Abnormal tire pressure: The system typically alerts when the pressure is below 1.8 bar or above 3.0 bar. At this point, tire inspection and pressure adjustment are required. Tire pressure monitoring system not reset: After inflating the tires, if the tire pressure monitoring system is not reset in time, it will still record the previous data, causing the tire pressure monitoring light to illuminate. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is directly installed inside the tire and connected to the tire inflation valve. If the sensor is damaged due to impact while driving, the tire pressure warning light will also come on. For sensor damage issues, only a complete replacement with a new part is possible.
When I saw the tire pressure warning light flashing, my heart sank because it indicated a problem with the tire pressure. It could mean a tire is leaking or the pressure is too low. I once experienced the light flashing on a rainy day and found a nail puncturing one of the tires. It's crucial to pull over and check immediately. Buying an inexpensive tire pressure gauge for regular checks is wise, and the normal range is the value marked on the door label. Insufficient pressure can cause uneven wear or increase the risk of a blowout, especially when driving at high speeds, which may lead to loss of control. If all tires are normal but the light still flashes, it might be a faulty tire pressure monitoring sensor or a dead battery, requiring professional repair. Regular maintenance, like checking the pressure monthly, is essential, especially in winter when temperature fluctuations are significant. Developing this habit helps prevent minor issues from becoming major problems, ensuring safer and more fuel-efficient driving.
