TPMS Constant Flashing

I’ve done a bit of searching but couldn’t find an answer:

dealt with a “60 second flash then goes solid” light for awhile. Shop diagnosed one bad sensor, mentioned another was low.

Had them replace the one and they said to drive it for 20 miles or so and it should go off. That didn’t work.

Took it back to them and they said another was dead. Replaced it (free of charge) but they still can’t get the light to go away. They said they tried everything from programming them and so on and finally mentioned I should take it to Toyota as it could be a bad TPMS module or that it needs to be programmed by them or maybe the old TPMS module can’t detect the new sensors? Idk, they seem at a loss.

Well now my tire light no longer flashes then goes solid. It’s a faster flashing and doesn’t stop.

Any ideas before I go the route of electrical tape over the light?

Thanks in advance!
