My tire pressure light has been on for 2 years, through tire changes and umpteen pressure checks by me and the tire shop. Had the codes pulled at the dealer this week for an unrelated problem and there's nothing there. Their Crossfire tech told me that some Corssfires will suddenly have code and sensor problems after driving through standing water on the streets. Great.

The point is, it won't clear and it won't ever go off. Gremlin.
