Where is the tire pressure sensor located?

Tire pressure monitoring sensors are installed on the tires, usually at the valve stem position. The tire pressure monitoring display is typically placed on the center console. The central area of the center console houses many electronic devices, which may cause some interference with radio frequencies, especially from devices like electronic eyes. Tire pressure warning light: The tire pressure monitoring indicator is a yellow symbol featuring an irregular circle without a seal on top, with four small spikes at the bottom and an exclamation mark inside. When the tire pressure monitoring light illuminates, it indicates abnormal tire pressure. Abnormal tire pressure generally occurs due to the following three reasons: Abnormal tire pressure: The system typically triggers an alarm when the pressure is below 1.8 bar or above 3.0 bar. In such cases, tire inspection and pressure adjustment are necessary. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset promptly, the system continues to record the previous data, causing the tire pressure monitoring light to stay on. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is directly installed inside the tire and connected to the tire inflation valve. If the sensor is damaged due to impact while driving, it can also cause the tire pressure warning light to illuminate. For sensor damage issues, the only solution is to replace it with a new component.
From my car repair experience, I know that the tire pressure sensor is hidden at the valve stem position inside the inner wheel hub, directly mounted on the rim inside the tire, which allows accurate monitoring of air pressure. These sensors are usually wirelessly connected, sending signals to the car's computer system. Once the tire pressure is low, a warning light will illuminate on the dashboard. When you change tires or perform balancing, be careful not to damage them, otherwise the signal may be lost or detection may become inaccurate. The sensor's battery lasts 5 to 10 years, and when it ages, it needs to be replaced at a cost of around 100-200 yuan per unit. Overall, this device is truly a guardian of driving safety, preventing tire blowout accidents. It's recommended to regularly maintain and inspect it to avoid trouble. Additionally, installation methods may vary slightly for different types of vehicles, and high-end cars also integrate temperature detection to avoid false alarms from cold tires.
