What is the reason for the persistent yellow light on the MG6 tire pressure monitoring system?

The reason for the persistent yellow light on the MG6 tire pressure monitoring system is that the tire pressure in one of the MG6's tires is too low. High-speed operation increases the tire temperature, leading to a rise in tire pressure, which triggers the yellow light on the tire pressure monitoring system. The reset method is as follows: first, turn on the ignition switch, then press and hold the tire pressure monitoring reset button until you hear a "ding" sound before releasing it. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the fault light on the dashboard will turn off, completing the tire pressure reset. Tire pressure monitoring automatically monitors the tire pressure in real-time during vehicle operation and alerts the driver to tire leaks and low pressure to ensure driving safety. There are three commonly used tire pressure monitoring methods: Direct tire pressure monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. The system automatically alerts when the tire pressure is too low or there is a leak. Indirect tire pressure monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to other wheels. By comparing the differences in rotation speeds between tires, the system monitors the tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to the Tire Pressure Monitoring System (TPMS): It combines the advantages of both systems mentioned above. Direct sensors are installed in two diagonally opposite tires, and a four-wheel indirect system is also equipped. Compared to using only a direct system, this hybrid system can reduce costs and overcome the indirect system's inability to detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time data on the actual pressure in all four tires as a direct system does.
I've been driving my MG6 for a while, and recently the tire pressure monitoring light has been staying on with a yellow warning. I'm a bit nervous. I asked a mechanic, and he said this is usually caused by abnormal tire pressure, like being too high or too low. The MG6's system is very sensitive; even a slight difference can trigger the alarm. It could also be a sensor issue, such as a dead battery or loose wiring. If you feel anything unusual while driving, like the steering wheel being unstable, it could be dangerous. He suggested using a household tire pressure gauge to measure the pressure in all four tires and adjusting them to the standard value first. If the light doesn't go off, take it to a professional shop to check the sensors—replacement costs aren't high. Don’t take it lightly; safety comes first.
