My light came on coming home from church tonight. Stopped by AutoZone, the code is:

P0453 Evaporative Emission Control System Pressure Sensor High Input

So, is this something potentially serious? Car runs fine. Guy at A-Z said, "I'd remove and re-tighten my gas cap and give it a day or so to clear, if it won't clear, then spend some money to have it looked at".

Hate to head for the Dragon if there is a chance I'll be flat-bedding it to some garage somewhere! I guess I could stop by the dealer's on the way up ( no Chrysler dealer here in town anymore, but the dealer I bought it from is on the way... if I go thru Gainesville like I did last year.)

But I can see troubleshooting the fuel and electronics systems taking DAYS.
