What is the reason for the tire pressure warning when the tire pressure is normal?
2 Answers
The reasons for the tire pressure warning when the tire pressure is normal are: 1. Malfunction of the tire pressure detector or receiver module; 2. The car quickly driving over uneven road surfaces; 3. Slow air leakage caused by a punctured or aged tire. The purpose of the tire pressure warning is to: prevent accidents, extend tire service life, and reduce wear on the suspension system. Methods to address the tire pressure warning include: 1. Display the instrument's tire pressure and temperature readings to observe if there are any abnormalities; 2. Check if the tire with low pressure is leaking; 3. Inspect whether the tire pressure monitor is malfunctioning.
I've been driving a car for several years and occasionally encounter false tire pressure alarms despite normal tire pressure. This is mainly due to issues with the tire pressure sensors—either the battery is depleted after prolonged use, sending incorrect signals, or sudden temperature changes cause minor pressure fluctuations that confuse the system. Once, I even got an alarm right after inflating the tires, only to find out the sensor was dirty or loose. Additionally, electronic systems can be affected by nearby electrical interference, such as areas with strong cell tower signals. To resolve this, try driving at highway speeds to let the system reset automatically. If that doesn't work, visit a repair shop for professional diagnostics and sensor replacement, which usually costs around 100-200 yuan. Don't overlook these small issues—safe driving is no trivial matter.
