This phenomenon is generally caused by the failure of the tire pressure monitoring system of the vehicle. It is necessary to timely check whether the tire pressure sensor is in normal condition, and timely repair the fault information to zero, so as to prevent the subsequent use of the vehicle. The engine is the heart of the automobile, so the tire pressure of the tire is the blood pressure of the automobile, which plays an important role in the performance and power performance of the automobile.

Although the tire pressure is declared, the reason for the normal tire pressure may be that the tire is stuck, the very slow air leaks, or the tire pressure sensor battery is dead.

1. The tire pressure monitoring lamp caused by tire puncture is often turned on. In this case, there is usually very slow air leakage. Finally, when the tire is unknown, it can be measured with a tire pressure gauge. The front 2.3 and the rear 2.5 can be supplemented if the air is insufficient. Then observe the tire pressure warning lamp and turn it on in a few days. It may be necessary to check the tire.

2. Tire pressure monitoring can be divided into external and internal sensors according to the sensor installation position. The external sensor is installed at the inlet and outlet of the tire, and the internal sensor is installed inside the tire. Both sensors need to drive the battery to work. The external battery life is 1-2 years, and the internal battery life is 5-8 years. The tire pressure sensor cannot work after the power consumption.

3. The tire pressure monitoring system of some models is a self-learning process. After we repair or inflate the tire, we need to reset the tire pressure data. Otherwise, even if the tire pressure is normal, the monitoring system will continue to keep the original fault code, so the tire pressure lamp will turn on.
