WARNING: This page is about a different car, the 2022 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The TPMS warning indicator is used to indicate both a low tire pressure event and a possible system fault condition. The message center displays additional information associated with the low tire pressure event or the system fault condition. Occasionally, the warning indicator and message center indicate faults that cannot be resolved by the customer. Treat these as TPMS faults that must be serviced.
