What's the matter with the tire pressure warning?
1 Answers
The main reasons for the car's tire pressure warning are: 1. The tire pressure data was not reset after tire repair or inflation. After repairing or inflating the tire, the tire pressure data needs to be reset. Otherwise, even if the tire pressure is normal, the monitoring system will retain the original fault code, so the tire pressure light will still be on. Generally, you just need to go to a 4S shop and ask the staff to use a decoder to clear the original fault code. If there is a tire pressure reset button on the car, you can also perform a manual reset. 2. The battery of the tire pressure sensor is dead. Tire pressure monitoring sensors can be divided into external and internal types based on their installation position. The external type is installed on the tire's valve stem, while the internal type is installed inside the tire. Both types of sensors require batteries to operate. The battery life of the external type is 1-2 years, and the internal type is 5-8 years. Once the battery is exhausted, the tire pressure sensor will not work, causing the tire pressure light to come on even though the tire pressure is normal. 3. Valve stem leakage, the car being idle for too long, or external temperature effects. When the car's tire pressure is abnormal, the tire pressure warning light on the dashboard will come on. At this time, the owner should pay attention to checking the tires. If the tire pressure light comes on while driving, it is best to reduce speed, control the steering wheel, and find a safe place to check. Whether the tire pressure light disappears afterward or not, it is necessary to go to a nearby repair shop for a recheck as a precaution.
