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

[SawyerDella]

The reasons for the tire pressure monitoring alarm when the tire pressure is normal are as follows: Malfunction in the tire pressure sensor or receiver module: This is a relatively rare occurrence, as tire pressure monitors generally have good durability and their lifespan can usually match that of the vehicle. However, signal interference can sometimes occur, which may cause the tire pressure sensor to give false alarms. Driving quickly over uneven road surfaces: When the tire is impacted at high speed, the internal tire pressure may increase, especially when driving in summer. The thermal expansion and contraction of air can also trigger the tire pressure warning. Minor tire puncture or slow leak: Sometimes, a tire may be punctured or experience slow leakage due to aging. These minor pressure fluctuations may not be noticeable to the naked eye, but the tire pressure monitoring system can detect them.
