Where is the built-in tire pressure monitoring installed?
2 Answers
The built-in tire pressure monitoring is installed inside the tire or outside the valve stem. Its principle is: using the sensing function of ABS to compare the number of rotations of the tires. A tire with insufficient pressure will have a shorter circumference, and if one of the four tires has insufficient pressure, its rotation count will differ from the others while driving. The method to eliminate the tire pressure warning light is: 1. Press the car's brake pedal and press the one-touch start button until the vehicle's power is fully on; 2. Inflate all four tires to the standard pressure; 3. Press and hold the tire pressure warning light reset button. Precautions for tire use include: 1. Worn tire treads can reduce grip, increase the risk of blowouts, and impair the tire's ability to expel water and debris; 2. Regularly check tire pressure; 3. Remove foreign objects from the tires to prevent punctures that could lead to leaks or blowouts; 4. Rotate tire positions every 10,000 kilometers to evenly distribute wear, prevent uneven wear, and extend tire life.
I've been repairing cars for many years and often encounter this question. The built-in version of the tire pressure monitoring system is essentially a small sensor installed inside the tire, fixed to the rim at the valve stem position. When the tire is removed, you can see it snug against the rim, measuring tire pressure and temperature data, then transmitting the information wirelessly to the dashboard display to ensure tire safety while driving. The advantage of this built-in type is that it's less prone to damage or theft, suitable for all road conditions, but installation requires professional tools to remove and reinstall the tire, which is more labor-intensive. If you notice the dashboard warning light during daily driving, it might indicate the sensor's battery is depleted or there's poor contact, so it's advisable to visit an auto repair shop promptly to avoid under-inflation risks leading to a blowout. In summary, choosing the built-in type offers better durability, with maintenance requiring a battery replacement approximately every 5 years.
