If you've recently topped off your tire pressure and the TPMS light is still on, it can be frustrating. This situation may arise for a variety of reasons.
One possibility is that the sensors in the tire may need some time to recalibrate after being filled. It's also possible that the sensors themselves are malfunctioning.
Additionally, there could be an issue with the TPMS system that requires further investigation. If the light persists, it may be wise to consult a professional.
