So if I am reading the service manual correctly and with what others have said here, the light should not have come on while in storage. Not until I drive the car over 20 MPH, which I would never have done without checking tire pressure before leaving the driveway anyhoo.

Important to note, my wife's Sebring TPMS will activate a low tire warning without moving first. More than once I have started her Sebring and be greeted with one or more tires in alarm mode. Also noteworthy is the lights would not go out until we drove the car. This system has individual warnings for each tire and also indicated the pressure on the dash. Much more fancy system than we have on our Xfires so I am sure I am comparing apples to oranges here.

This then would seem to indicate I have other issues. Specifically a Low or dead battery in one or more sensors maybe?? Would that manifest itself while in storage or would that need the 20 MPH rotation to light the warning?

Oh well, makes for good conversation on a snowy day anyhoo. I will pump up all tires to 32, drive the car like hell and see what happens come April. Light stays on after that I pull pin #2 and relocate it to space #6 on the connector. Problem solved.
