What to do if the tire pressure warning light comes on after a tire repair?

The solution to the tire pressure warning light coming on after a tire repair is to add more air to the tire, as this indicates the tire pressure is too low. A tire pressure warning means that a problem with tire pressure has been detected, alerting the driver to stop and check. The reasons for a tire pressure warning include: 1. A punctured tire; 2. Prolonged driving or failure to replenish tire pressure in time; 3. A malfunction in the tire pressure sensor; 4. The tire pressure module not being reset after a tire change or repair. The functions of the tire pressure warning are: 1. To prevent accidents; 2. To extend the service life of the tires; 3. To reduce wear on the suspension system. Methods to address a tire pressure warning include: 1. Displaying the tire pressure and temperature on the dashboard to check for any abnormalities; 2. Observing whether the underinflated tire is leaking; 3. Checking if the tire pressure monitor is malfunctioning.
I just encountered the same issue last time. Shortly after getting the tire repaired, the warning light came on, which really freaked me out. I immediately pulled over to a safe spot to check. First, I walked around the car and noticed the recently repaired tire looked fine, and the others weren’t noticeably flat either. I suspected the tire pressure monitoring system might need a reset, so I dug out the manual and found the reset steps (the location varies by model, so you’ll have to figure it out yourself). After resetting, the light turned off on my way home. However, it’s crucial to check if the puncture was properly sealed—driving on the highway with a slow leak is very dangerous. If the reset doesn’t work, it’s best to revisit the tire shop to recheck the pressure, in case the technician didn’t inflate it enough or the sensor was damaged during the repair.
A tire pressure warning after a patch is usually a minor issue, no need to panic. Having driven for over 20 years, I've found there are just a few common causes: first, the tire might be underinflated or overinflated; second, the tire pressure sensor might have been bumped during removal or installation; third, the repair shop might have forgotten to reset the system for you. My approach is to pull over immediately and use the onboard tire pressure gauge to check all four tires (if you don't have one, press them by hand or check the tread contact with the ground). If the pressure is normal, reset the system—the reset button is usually near the steering wheel or in the central control screen. After resetting, drive another couple of kilometers and it should be fine. If the problem persists, go back to the repair shop and have them check it with professional equipment.
This is a common issue. The post-repair tire pressure warning mainly occurs because the system needs to relearn the tire status. First, check if the tire is leaking (especially at the repaired spot). If there's no leak, simply locate the tire pressure reset button in the vehicle and perform a reset. The warning light should disappear after driving for a few minutes. If the light persists, it could indicate a damaged sensor from wheel removal during repair or a hidden leak in the tire itself. In such cases, avoid high speeds and visit a professional auto repair shop promptly to read the fault codes with a diagnostic tool. It's advisable to keep a simple tire pressure gauge in the glove compartment for emergency use.
