How to Deal with Abnormal Tire Pressure Signal in BYD Tang?
2 Answers
For abnormal tire pressure signal in BYD Tang, you can perform a tire pressure reset. If the issue persists, it indicates a tire pressure monitoring system malfunction. Below is a detailed introduction to the concept of car tire pressure and factors affecting it: Definition of Car Tire Pressure: Car tire pressure refers to the air pressure inside the tire, which is akin to the blood pressure of a car. The level of tire pressure plays a crucial role in the performance and power of the vehicle. Factors Affecting Tire Pressure: Tire pressure is significantly influenced by seasonal factors. In summer, high temperatures can cause tires to heat up during driving, and high tire pressure may lead to blowouts, so the pressure should be slightly lower. In winter, tire pressure should be slightly higher than in summer due to thermal contraction and expansion. Generally, a tire pressure between 250kpa and 280kpa is suitable for cars in winter.
My BYD Tang also showed an abnormal tire pressure signal a few days ago, with a warning light displayed. At first, I thought it was just low tire pressure, so I quickly pulled over to a safe spot and checked with the built-in tire pressure gauge. It turned out the left front tire was as low as 2.0 bar. Common causes of air loss could be a slow leak or a nail puncture, and sure enough, I found a small nail after inspecting. However, even after inflating it to the standard 2.5 bar, the system still gave an alarm, so I took it to the 4S shop for a check. It turned out the sensor battery was depleted and needed replacement. Such issues shouldn’t be taken lightly, as prolonged abnormal tire pressure can increase fuel consumption or the risk of a blowout. Personally, I’ve made it a habit to manually check the tire pressure every month. I keep a cheap tire pressure gauge in the trunk for easy access, which is both convenient and safe.
