The TPMS system light flashes a bunch of times, then stays on solid. I'm guessing one or more TPMS sensors need new battery, or needs to be replaced. I don't suppose there's a way to test them individually? Also, does the spare tire have a sensor? I'm looking up parts on Auto Zone and Amazon, and they come in kits of 4; not 5.

Thanks, BAT!

this may sound strange, but try to find a good strong magnet. Pass that by a few times by

It seem to work.

In the tpms ultra kit we have at work, there is a big magnet in the kit.

Think, if you have a dead speaker lying around,why not try it.

If you think I am joshing you, no I am not, I do this every day.

this video is boring, but shows what my lame arse is trying to say.

magnet @ 2min 40ish mark

mind you, a 10 watt speaker will not suffice, you will need a serious driver magnet. 500w should do.

Circumference also should be same. So de virginize a blown driver, you have a great tpms wake up tool.

:D:fixed:

the tpms sensors usually have a battery in them, For physics reasons my beer induced brain does not want to talk about. the fluctuation revives the bat enough to transmit the rfid chip to module, and then you can determine.

Other cool way of doing away all together with that is this is see link below.



Would I buy it, hell no.

I just kick the tires.
