Why does the tire pressure warning light come on when the tire pressure is normal?

[DiDakota]

The reasons for the tire pressure monitoring alarm activating despite normal tire pressure are as follows: 1. Malfunction in the tire pressure sensor or receiver module. This is a relatively rare occurrence, as tire pressure monitors generally have good durability and can last as long as the vehicle itself. However, signal interference may sometimes occur, potentially causing false alarms from the tire pressure sensor. 2. The vehicle rapidly driving over uneven road surfaces. When tires hit obstacles at high speed, the internal tire pressure may temporarily increase. This is especially likely during summer driving, where thermal expansion of air can trigger the tire pressure warning. 3. A very slow tire puncture that's not visibly noticeable. Sometimes tires may have minor punctures or slow leaks due to aging. These small pressure fluctuations are often undetectable to the naked eye but can be picked up by the tire pressure monitoring system.
