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.

 

Slow walk it. Mine did this when we first had it. Went away on it's own. But yea, the battery can die, some folks don't replace them when they buy tires.

 

Here’s my question, is this a take it to the dealer issue or take it to a tire shop issue?

Neither, this is an ignore it and use your tire gauge issue. Just another nanny feature nobody needs.

 

its more than just a dummy light for tire pressure. On my 09 CRV it comes and goes on its own. The Tire Pressure Monitoring System (TPMS) and the Vehicle Stability Control (VSC) system are interconnected. The TPMS monitors tire pressure, and if it detects an issue, such as low tire pressure, it can affect the VSC system's functionality. This is because the VSC relies on accurate tire pressure to maintain proper traction and stability. If the TPMS light is on, it may disable certain VSC features to prevent incorrect operation in potentially unsafe condition

 

I've had my 2008 show the TPMS showing for awhile now. Decided to fix it myself. I ordered the following:
Autel TS508WF
(4) Autel MX sensors
BeadBuster XB-450i, Extended Clamp Arm (for alloy wheels)
Tire lube
I was very hesitant to start this venture, but after watching a few YouTube videos I was ready. After the first tire, I learned how everything worked. The other 3 tires I was able to get everything done in 15 minutes each! That includes taking the tire of the car, breaking the bead, replacing the sensor, inflating the tire, and torquing the lug nuts. Remember to activate the sensors before installing them. I forgot; I called Autel, they have very good customer reps. For me the only thing I had a problem was the programming part, that's because I'm computer/electronics-stupid.

 

BeadBuster XB-450i, Extended Clamp Arm (for alloy wheels)

Somehow I missed this reply.
I have the same setup, except I have a VEVOR bead breaker with an extended arm. It works great on steel wheels, but useless on alloys as I can only break the bead on the back of the wheel. Is your 450i the same or can it fit between the spokes?
Thanks.

 

When the letters TPMS light comes on then it means there is an issue in the system. Sensor battery is dead or receiver is not seeing the signal from the sensors. When the image of a tire with the exclamation point lights up, it mean the air pressure is low on one or more of the tires.

Yes, the Autel TS508 is a handy tool. Expensive if you only use it once or twice after purchase. But, once I saw someone use it to check their tire pressure, I wanted one. Gives readings quickly and tells you the state of the sensor battery.
