This cold spell suddenly shows up as a fuel cap error, i have seen it before also when the weather gets very cold and then it goes away when it warms up.
Was just curious if its just me :).
 
First thing that comes to mind when there's issues during the cold is something loosened up and it's creating a fault. It could very well be the gas cap itself which I've seen before. But also it could be something else to do with the evaporative emissions system where there's a leak on one of the hoses. That's located underneath on the passenger side. Check the rubber seal on the gas cap to see if there's any cracking. The gas cap itself has a built-in valve that could also be an issue. Other than swapping with an identical gas cap and testing, you may need to replace it and see if it goes away. If not, the evap system, the gas tank hoses are the next culprit.
 
Thank you for replying, the interesting thing is weather warmed up and the error went away completely. Should i still be concerned that there is an underlying issue ?
 
No underlying issues. My awd light cameras on for 5 minutes a couple days ago. My stereo button wouldn't work either for 1 minute a couple days ago. The cold can cause issues that only last a few minutes
 
for me it's the other way around my open fuel cap message goes away when it's to cold and that goes for the check engine light also
that means that my evap problem must be one rubber hose somewhere that's leaking
