If you have a sensor battery going dead that could cause the TPMS light to come on, however it should also indicate a no pressure tire too if it is not sending a signal. Also, I dont know what pressure you guys run in your tires, but on my X I run 40 psi all the way around, trying to get the most mpg's out of it. Also, you need to be setting your tire pressure with the tires being cold, that means you haven't driven anywhere. Or if you have been driving then you really need to "bump" up the pressure to a warm pressure instead of "cold" pressure.
You can always stop by a Discount Tire / America's Tire and they will set your pressure and scan the TPM sensors and tell you if they are working, all for free.
