The other day the TPMS light came on. Checked the tire pressure and everything was good. Went for a drive, light started blinking and then it went solid and then went away. It came back again the next time I drove it. This continued a few more times. I'm thinking there's a problem with one of the sensors.

I've owned my 4R since it was new and have what I'm sure are the factory TPMS. Tires were replaced for the 1st time back in March and I never had the TPMS light come on other then when the tire was low at one point and adding air turned it off.

Anyway, I took it up to a tire place and they were checking the sensors. The tech said it was weird because first one of the sensors would read, then it wouldn't, it looked like the problem would move from tire to tire. He actually showed me while he was reading the sensors with the tool.

I have 4 factory sealed Toyota TPMS sensors that I was going to ask them to program and swap out, but they told me they're machine couldn't program the Toyota ones..

Decided to take it home and lo and behold the TMPS light is off..I'll admit my ignorance to the whole TPMS system..I'm very much mechanically inclined but this is not in my wheelhouse. I would hate to have to replace all 4 sensors. Looking for suggestions.

Thanks in advance.
