Batteries are supposed to last 10 yrs. or x amount of miles in the sensors.
I've only see the TPS symbol indicating low pressure on any of the 4 or so TPS cars I've had.
If you see a fault may want to dealer to check out, they can cost about $40 a sensor plus rebalancing and mounting so better to get it done under warranty.
