Where is the tire sensor located?

Tire pressure sensors are installed on the tires, typically at the valve stem position. The tire pressure monitoring display is usually placed on the center console. The central area of the dashboard houses numerous electronic devices, which can have some impact on radio frequency interference. Tire pressure monitoring principles: Direct tire pressure monitoring. Pressure sensors installed in each tire directly measure the tire's air pressure, and wireless transmitters send the pressure information from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. When the tire pressure is too low or there is a leak, the system automatically alerts the driver. Indirect tire pressure monitoring. When the pressure in a tire decreases, the vehicle's weight causes that tire's rolling radius to become smaller, resulting in a faster rotation speed compared to other wheels. By comparing the differences in rotation speeds between tires, the system monitors tire pressure. Indirect tire pressure alert systems essentially rely on calculating the tire's rolling radius to monitor pressure. Tire usage precautions: While driving, tire pressure directly affects vehicle handling and the safety of passengers. At high speeds, significant heat is generated, causing tire pressure to rise. If the tire pressure is already too high, this can easily lead to a blowout. When tire pressure is too high, the contact area between the tire and the road decreases, reducing friction and affecting braking performance. Conversely, if tire pressure is too low, the contact area increases, raising friction and reducing driving efficiency, which leads to higher fuel consumption. Under the vehicle's weight, the sidewalls of underinflated tires endure excessive pressure, increasing the risk of a blowout.
Tire pressure sensors are typically installed inside the wheel near the valve stem, mounted directly on the wheel hub. This design allows for direct monitoring of tire pressure changes. With years of driving experience, I find this layout quite ingenious because the sensors can transmit real-time data to the vehicle's onboard computer, alerting you to inflate the tires promptly when pressure is low, thereby avoiding the risk of a blowout. During actual maintenance, when you replace tires or perform balancing, technicians take care not to damage the sensors, as this could cause false fault alerts. Personally, I recommend checking the sensor's seal every six months to prevent air leaks or water accumulation from affecting readings—after all, driving safety comes first.
