What is the symbol for the tire pressure monitoring light?
2 Answers
The tire pressure monitoring indicator is a yellow symbol, an irregular circle with no seal on top and four small spikes at the bottom, containing an exclamation mark inside. The illumination of the tire pressure monitoring indicator indicates abnormal tire pressure. Abnormal tire pressure generally occurs due to the following three reasons: Abnormal tire pressure: It usually triggers an alarm when the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator to light up. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, used to monitor tire pressure, is directly installed inside the tire and connected to the tire inflation port. If the tire pressure sensor is damaged during driving, it will also cause the tire pressure warning light to illuminate. For sensor damage issues, only replacement with a new component is possible.
I remember a few years ago my car's tire pressure monitoring light suddenly came on—it was a yellow icon shaped like a tire cross-section or sometimes with an exclamation mark, indicating the tire pressure monitoring system detected abnormal pressure. I was on the highway at the time and got quite a scare because the light could mean one of the tires was underinflated or had a leak. As someone who frequently drives long distances, I knew this couldn’t be ignored. Low tire pressure can lead to increased tire wear, higher fuel consumption, and even blowouts. I immediately pulled over at a service area and checked the pressure with a portable tire gauge—sure enough, the front right tire was leaking. I quickly went to a repair shop to get it fixed. To avoid such hassles, I make it a habit to check my tire pressure monthly. That warning light is a crucial safety reminder—never delay addressing it.
