My P0447 CEL has been on since a week after i bought the car which was in the spring just as it was warming up...
Now as winter hits and the temperature stays consistently below 0C the light went out again... At first i thought it burnt out. but went to "on" with out starting and it still works...
However i still cant fill the gas tank with the gas nozzle on full.
Takes 10 minutes to fill the damn thing
Oh and my foglight is full of water (ice)..
still works though.
Any ideas as to why the light stopped?
