Where is the tire pressure sensor located in a car?

Car tire pressure sensors are located on the inner side of the tire. They can accurately measure the temperature and pressure inside the tire. The tire pressure monitoring sensors transmit information frames to the dashboard via wireless signals at regular intervals to the vehicle's body controller and bus. Drivers can obtain the pressure and temperature values of each tire through the dashboard display. When the pressure or temperature of a tire exceeds the alarm threshold, the dashboard can accurately display the position of the problematic tire and issue visual, audible, or text alarms. Car tires are crucial components of a vehicle, directly contacting the road surface and working with the car's suspension to absorb shocks during driving, ensuring good ride comfort and smooth driving.
I've been driving for decades, those tire pressure sensors are right next to each tire's valve stem, mounted directly on the inner side of the rim, secured with a metal bracket in a concealed position to avoid damage from rocks or road conditions. The design places them near the valve for immediate pressure change detection, with signals wirelessly transmitted to the dashboard for alerts. During one trip, my sensor warning light came on, and upon inspection, I found the bracket on the rim had loosened—tightening it promptly fixed the issue. Regular tire pressure checks can prevent problems; if a sensor fails, it needs replacement, which significantly impacts driving safety.
