P0449 error code - Check Engine light

[lawadm1]

2005 GTP

My son just recently went on spring break to Gatlinburg,TN and took my 2005 GTP. During the trip through the mountains, the check engine light came on. He took it to Autozone, and it's throwing the P0449 error code. When I google it, it says:

Evaporative Emission Vent Solenoid Control Circuit

Any ideas what this means, and how to clear it?

TIA,
Jeff

Had the same thing happen when we took our minivan through the Appalachian mountain range on the way to Roanoke. Reset the code and it never came back.

Best guess is, it had to do with the rapid change in air pressure from the difference in elevation. Reset and forget. I'd be willing to bet it won't come back.
