Does the Civic still have tire pressure monitoring after changing the rims?

The Civic still has tire pressure monitoring after changing the rims; replacing the rims does not affect the factory-installed tire pressure monitoring system. Civic specifications: Fuel consumption: 5.0-6.4L, Body structure: 4-door 5-seat sedan, Engine: 1.0T/1.5T, Transmission: 6-speed manual/CVT, Drive type: Front-wheel drive, Fuel type: Gasoline. Tire pressure monitoring: Tire pressure monitoring is a system that automatically monitors tire pressure in real-time during driving and alerts the driver in case of tire leakage or low pressure to ensure driving safety. There are three common types of tire pressure monitoring: Direct tire pressure monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure data for each tire. The system automatically alerts the driver if the tire pressure is too low or if there is a leak. Indirect tire pressure monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel 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 monitoring systems actually rely on calculating the rolling radius of tires to monitor pressure. Tire Pressure Monitoring System (TPMS) introduction: It combines the advantages of the two systems mentioned above. Direct sensors are installed in two diagonally opposite tires, and an indirect system is used for all four wheels. Compared to a fully direct system, this hybrid system can reduce costs and overcome the limitation of indirect systems, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires like a direct system.
I also changed the rims on my Civic last year and made sure to ask the mechanic to handle the tire pressure monitoring system (TPMS). The original rims had four coin-sized sensors fixed right next to the valve stems. During the replacement, the workers carefully removed the sensors from the old rims and reinstalled them on the inner side of the new rims, then performed a sealing test with specialized tools. After driving for over half a year now, the tire pressure display on the dashboard has been working perfectly, even monitoring real-time pressure changes during rainy highway drives. The key is to inform the modification shop in advance to preserve the original sensors—they are usually skilled at this. Some car enthusiasts skipped reinstalling the sensors for convenience when changing rims, only to end up with constant warning lights on the dashboard, forcing them to spend extra money on new sensors later.
Over a decade of car repair experience, I've encountered numerous Civic modification cases. Technically speaking, whether to retain the tire pressure monitoring system entirely depends on the sensor's relocation. The factory sensors are miniature transmitters directly mounted on the wheel rims, transmitting data via Bluetooth. When changing rims, simply transplant the sensors intact to designated positions on the new rims, perform proper dynamic balance calibration, and the system will continue functioning. Pay attention to whether the new rim's inner cavity dimensions can accommodate the sensors - it's recommended to choose modification rims with factory certification. After installation, diagnostic tools must be used to rematch the ID codes, otherwise data transmission delays may occur. Regular inspection of sensor batteries is also crucial, as they typically last five to eight years.
Whether the TPMS works after changing rims depends on these three steps: First, when removing the old rim, ask the mechanic to carefully detach the sensor without scratching the wiring with screwdrivers; Second, install the sensor in the original position on the new rim and ensure proper sealing to prevent air leaks; Third, after mounting the tire, be sure to drive for about ten minutes to allow the system to automatically recognize it. Last week, a colleague skipped the third step when changing rims, resulting in constant abnormal tire pressure warnings on the dashboard. It only returned to normal after resetting with an OBD tool connected to a phone. Remember, the sensor is like the tire's ID card—it must be taken along even when changing its 'residence.'
