There are ways to disable (defeat) the TPMS module. So you don't have to look at that annoying light on your dash.

I will not post up links, because the ones I found online all involve cutting wires to the TPMS module and basically short circuiting them to ground. Yuck. That's an easy way to zap your PCM if you don't know what you're doing.
-----------
In the 5.0 Coyote Mustang world, the TPMS defeat can be done with freeware from the web called ForScan and a laptop in about 5 minutes via the OBD-II connector. You can literally just re-program the TPMS module to an "OFF" status instead of "On". There may not be a whole lotta Furd fanatics around here, but that ForScan app is wicked powerful. And it is supported by Ford.

I don't know if there is an equivalent type of method for Tacomas. But that is the only way I would do it. By (re)programming the PCM and turning the TPMS module OFF where the PCM is "fooled" into thinking it doesn't even exist. On Fords, I know for certain this does not cause any other consequence such as a check engine light for something like TPMS Module not Communicating.

Again, not sure if this possible with Tacomas. If so, maybe someone can post up the How To.

Cheers!

I have enough discipline to ignore the light and not let it take control of my emotions.
