    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!

    The shop didn’t mention any trouble codes unfortunately. They replaced two of the 4 sensors at this point and have tried programming them and using their tool to reset everything. No joy there.

    Are you saying that just replacing 1 or 2 sensors could cause the light to not clear and that you have to replace them all at the same time?

    Well yes that could actually happen if you change the wrong two sensors or. Give it a think for a few minutes.

    Perhaps they replaced the wrong ones????
    You can replace one at a time. Usually, but not always, when one goes, the others soon follow.
    Maybe there equipment can't read/write to Toyota's computer.

    You can try another shop, parts store, or walfart.

    The old ones need to be deleted, then the new ones added.
    Some equipment is able to reprogram the new sensor with the dead sensors number.

    The link I put in post #3 will show you a way to get the trouble codes yourself. Then we can be talking about what is happening, instead of about what might be happening.
