What Is TPMS? How to Handle the Tyre Pressure Warning Light

That yellow tyre-shaped warning light is your TPMS telling you tyre pressure is off. Here's what it means — and what to do when it comes on.

What Is TPMS? How to Handle the Tyre Pressure Warning Light

TPMS(Tyre Pressure Monitoring System,胎压监测系统)在 2016 年后大部分新车已是标配,它实时监测四条轮胎的气压,出现问题时在仪表盘亮灯提醒。

两种 TPMS 类型

直接式:每个气门嘴内有独立传感器,直接测量各轮气压,精度高。

间接式:通过 ABS 轮速传感器间接判断气压变化,不需要额外传感器,但精度较低。

灯亮了代表什么?

TPMS 灯亮通常代表至少一条轮胎气压比标准值低超过 25%。

可能是一条,也可能多条同时低压。

天气突然变冷也可能触发(气温每降 10°C,气压约降 1 PSI)。马来西亚温差不大,多数是真的气压不足。

灯亮了该怎么办?

1. 尽快检查四条轮胎气压,充到车门边贴纸标示的正确压力。

2. 充气后低速行驶约 10 分钟,大部分车型会自动重置 TPMS 灯。

3. 如果灯仍不熄,按车主手册找 TPMS 重置按钮手动重置。

4. 如果反复亮灯,可能是传感器本身故障或轮胎有慢漏气,需要检查。

TPMS 传感器电池

直接式 TPMS 传感器内置电池,寿命约 5–7 年。

电池耗尽时仪表盘会亮 TPMS 警示,此时需要更换传感器(连同气门嘴更换轮胎时一起换是最佳时机)。

结论

TPMS 是很实用的安全系统,不要无视它的警示。灯亮先检查气压,简单充气通常就解决了。4M CARCARE 可帮你检查轮胎气压、排查慢漏气问题。
