Where is the car's tire pressure sensor located?

The installation position of a car's tire pressure sensor varies and can be categorized into built-in and external types. The built-in sensor is installed inside the tire, which is relatively more stable, while the external type involves adding a sensor outside the valve stem. The tire pressure monitoring sensor can accurately measure the temperature and pressure inside the tire. Tire pressure monitoring systems can be divided into two types: one is the indirect tire pressure monitoring system, which determines tire abnormalities through differences in tire rotation speed; the other is the direct tire pressure monitoring system, which involves installing four tire pressure monitoring sensors inside the tires.
As an experienced driver who has driven various models, let me tell you that the tire pressure sensor is usually located right on the tire's valve stem—that place where you normally inflate the tires. It sticks there like a small cap, directly measuring the pressure. Last time my warning light came on, the mechanic checked and found it was this little device acting up, positioned on the inner side of the tire near the wheel hub center. Knowing its location is crucial because incorrect tire pressure not only affects braking performance but also increases fuel consumption. Some older cars might not have sensors, but modern vehicles are generally equipped with them. I recommend checking its position every six months to avoid accidental damage during tire changes, which could trigger false alarms. Keeping an eye on the dashboard warning light while driving can save you a lot of trouble.
I'm a car tech enthusiast, and the cool thing about tire pressure sensors is their location on the tire's valve stem, where they're built-in and wirelessly transmit data to the dashboard system. Specifically, they're positioned in the central area of the wheel hub, and if you look from the side of the tire, they're easy to spot. During my modifications, I found that some sensors have batteries that need regular replacement; otherwise, unstable signals can cause false alarms. Positioned close to the tire's surface, they monitor tire pressure as the tire rolls to ensure safety. A reminder to everyone: their location is quite hidden, so be careful during maintenance to avoid scratches, or the entire system might fail, affecting the driving experience.
