the code is for an leak in the evaporative system. You can try a new gas cap, but there seems to be a common occurance where a valve fails and needs to be replaced. Do a quick search on the forum, I am sure it will pop up. As to the overheating, could be a few things. If it overheats while you are stopped, look at the fan and fan relays, if it happens while you are moving, could be a clogged radiator, something blocking the fins (think plastic bag stuck to it), if it is both, t-stat. Step one would be to verify you are not low on coolant.

When you say your coolant is not low, have you checked at the water pump or just the overflow/reservoir? I still had coolant in the reservoir when my water pump slowly pissed it all away, giving me the same messages you got on the DIC.
