So Ive had my k3s for about a year, and when i got them from tire rack I had them put in 4 NEW TPMS sensors. Put the wheels on last year, took it into toyota to get the new serial # put into the ECU, and since then everythings been fine. Took a 3 hour drive or so yesterday and noticed that when I went above ~65 for 5 min or so, the TPMS light on the dash would do the blink for 1 min, then steady on pattern, and it would stay that way till I dropped below about 45 then itd shut back off. For those who dont know, that pattern does not mean that tire pressure is an issue (checked that already anyway 33f, 30r), but rather that theres some sort of hardware issue in the system, (unable to communicate etc.). Anyway, im taking it into toyota today to see whats up, but while im doing that, anyone have ideas on why its doing this? anyone had this happen before?

THANKS

 

Did you ever figure this one out? I had this same issue happen yesterday. Planning on going into Toyota tomorrow to check it out
