The tutorial for replacing the battery of a tire pressure sensor is: 1. Use a wrench to unscrew the external sensor and remove the anti-theft washer upwards; 2. Place the sensor on a disc-shaped opener and unscrew the housing; 3. Remove the old battery and replace it with a new one. The tire pressure sensor is installed at the valve position or inside the tire. It uses the ABS sensing function to compare the number of rotations of the tires. The circumference of a tire with insufficient pressure will shorten, and the tire pressure sensor will receive this signal and function. The functions of the tire pressure monitoring system are: 1. To alert promptly when a tire is punctured, causing rapid or slow air leakage; 2. To alert when tire looseness causes unbalanced friction, leading to a tire temperature rise to 70 degrees Celsius, preventing blowouts; 3. To alert when the tire pressure is below the vehicle's set limit due to prolonged lack of inflation, preventing low pressure from causing a temperature rise and blowout.
Last time I encountered the tire pressure warning light coming on, I managed to fix it by replacing the sensor battery myself. First, you need to confirm your sensor type—the battery is usually CR2032 or CR1632, so getting the right model is crucial. The tools I prepared included a small wrench, flathead screwdriver, new batteries, and rubber gloves to avoid static electricity. The steps are: Park your car on safe, level ground, loosen the screws to remove the tire rim, locate the sensor position, and carefully open the casing or cover—don’t use excessive force to avoid damaging the parts. Replace the old battery with a new one, ensuring the positive and negative terminals are aligned correctly, then reseal and reinstall the tire. After reassembly, start the car and take a short drive to check if the tire pressure system displays normally. Take your time during the whole process; rushing might lead to wrong battery models or poor sealing, which could cause air leaks. I also recommend regularly checking tire pressure and battery life to replace faulty sensors in advance, ensuring safer and more worry-free driving.
