Without calling the dealership yet, anyone know what the code P 1281 is on a 2003 jeep?

Running to cool, got a lower temp than stock thermostat in it?

Yea. My radiator sprung a leak and the dealer fixed it under warrenty and also put in another thermostat just to make sure I didn't overheat again and after running cooler than normal for a few days, the light finally came on gave me that code. Guess it won't hurt any, but I'm in alaska and I need that hotter fluid for the heater.
Go figure.
