Tire sensor light cant decide what it wants to do

[hooey_b]

Hey all,

So recently, my low tire pressure light has came in (I have an 08 G37S, 6mt)....whenever I start the car, the light blinks on and off, roughly every second, then comes in solid once the car has warmed up some.


I've checked all pressures in my tires, all read 36 or 36.5 psi

I've checked all fluid levels, all are nominal (roughly halfway between what is marked as a minimum and max)


I'm assuming it's just a bad TPMS sensor, but I'd like to hear of any other possibilities, if there are any other possible situations going on with it.

Thanks in advanced-
