I would suspect a dead sensor battery, that was the cause in my case. So, a visit to a tire shop.
I bought an Autel TS508 scanner and a set of MX sensors. Only had to replace one sensor so far, the tool gave me the serial number of the dead sensor through its OBD connection and transferred it to the replacement, then updated and turned the warning light off.
Fairly expensive, but very handy, I was even able to scan my winter wheels prior to installing.

Thanks for your quick reply Wes, I was hoping you would chime in. A trip to the tire shop it is. I’ve seen you mention your Autel before, it does seem pretty handy/powerful. I’ve been looking at the BlueDriver scan tool, but haven’t pulled the trigger yet, maybe now is the time. The advertisement says it does TPMS codes, but I wonder if it does the serial number rewrite/updating. I kind of doubt it. Pray tell, how did you get the new sensor physically installed in the rim? I assume the tire shop, but curious minds and all.

I have a VEVOR tire bead breaker but, of course, it didn't work with my 3-season rims. Luckily my neighbor, who used to have a repair shop, still has a tire machine I can use. You don't have to remove the tire, just break the bead at the valve enough to remove/replace the sensor.
Cheers!

Ah, 10-4. I don’t have the Autel and I don’t have a neighbor with a tire machine, so it’ll be a trip to the tire shop for me.

Thank you Wes!
