Do you have the code for this living anywhere? I think I have a bad TPMS sensor in one of my tires and it sounds like your tool would be immensely helpful in figuring out which one.

here's the code: https://github.com/rouyng/tpms-helper

so far I have only tested it with Toyota sensors, so YMMV when used with other sensor types as I'm not sure if the rtl_433 output will be the same.

I also wrote a blog post when I first figured out how to test the sensors with rtl_433, before I wrote the script. probably useful for background information: https://www.r-c-y.net/posts/tpms/

Thank you for sharing. I have a Prius and the tire pressure alert is on even though all the tires appear fully inflated. Is there a way to determine which sensor is detecting low pressure?

Incredibly helpful, thank you! I actually just found your blog post on this. I happen to have a 2008 Corolla with the same issue, so my guess is that the sensors are very similar.
