Quick Question on TPMS
The last few days when heading out to work the TPMS sends an alert for both LF and LR, by time I make it a couple miles down the road, they both go away. I am attributing this to the tires warming up and pressure increasing. When I get to work and check the pressure, they are all within one pound of pressure to the others.
Is it a "warming" issue or should I be concerned about something else.
Thanks

The sensors still transmit pressure readings to the computer even when parked, only it is once every 60 minutes rather than the once every 60 seconds when the car is moving.
I have found here in Florida in the winter (30's-40's) my tire pressures will vary by 3-4 psi between cold and hot. I also have found a 1-2 psi difference between sensor pressure and tire gauge pressure. If you are running under 30 psi in your tires I would expect you to get the low pressure warnings as the ambient temperature decreases. The warning will be displayed once pressure is at 25 psi or below.

I converted my '99 system to the later '01+ system and that's the first thing different that I noticed on upon initial start-up. I get a tire pressure reading immediately upon start-up regardless of how long/short of a time the car has been parked.
