I was on the track when the "low tire pressure" light came on, so I checked all the tires and the pressure was fine. Later that day on the trip home the warning light went out and stayed off until last week. I was on a back road and having a great (track like!) drive and the light came on again - again all pressure is fine but the light will not go out now! Any idea on what the problem might be?

Sounds like the TPMS monitor is going bad - not one of the ones in the wheels but the master, so to say.

There are monitors on the inside of each wheel, attached to the valve stems, which do have batteries (I think). But from what I was told, there is a master TPMS unit for all of them - if all your pressures are ok then that is what I suspect.

The same thing happened to me. 2004 Viper. I finally took it to the dealer. The master TPMS module (part # 4815227AF) in the dash was bad. The wheel sensors were ok. Had to order a new monitor. $158 plus tax. They haven't installed it yet. $200 more to install, and 2 wasted afternoons at the dealership.
There are a number of prior posts on this. Before you go to the trouble of replacing the module, have the system reset at the dealers using the donut shaped magnet placed on each wheel in the correct sequence and their computer. Have him do it more than once. When I first received my 2006 coupe the low pressure light was on and stayed on. After consulting with Mark Jorgensen at Woodhouse and Chuck Tator, AKA "The Wizard", this is what worked. The key was doing it more than once - one right after the other. The system has not malfunctined since. If this does not work, the next step is to test each wheel stem monitor. One or more could be bad. They quickly change out assuming the dealer has the equipment to properly remove that part of the tire from the rim without damaging the rim - a very important thing to determine. The tire changing equipment involved is expensive and some dealerships do not have it. ( This is particularly important with the five spoke rims that first appeared in 2006. They have no lip.)
