    Default Town car gives code for engine heat up

    My 2005 Town car goes in to a 4 cylinder mode with temp gauge high. It works fine that way. If I were to shut off the engine and turn on, some times everything returns back to normal including the temp. It gives me the sign code : P1299.

    It only happens when its raining, on a dry day it just never happens. I did change the thermostat a few months ago, and I always check the coolant fan is working at that particular time, and yes, it does work, and yet every now and then the check engine light comes on, it goes in to 4 cylinder mode with a rough engine drive mode with temp high. I don't understand this, did any of you ever had this?

    It gives following codes, and the car only heats up when there is a lot of rain. My feeling is the water is going somewhere where it shouldn't.

    P0199 ECT circuit intermittent
    P0480 Cooling Fan 1 Control Circuit
    P0622 Generator Field F control circuit problem.
    P1285 Cylinder head over temp sensed.
