Answer 1

Heat causes things to expand and cold contracts things. It could be the hoses to the EVAP system or the EVAP canister

- EVAP canister or fuel tank leaks
- EVAP system hose leaking

Answer 2

I HAVE A 2006 nissan and my macanic told me when the tubes get hot they expand and a little vapor leaks causing light p0455 code to come on that is why when the temperature goes down the light go off. He told me to go to the dealer they will do a smoke test to see where the leak is ( the put a colored smoke into the system and see where it is coming out from that is the best way to find out where the vapour leak is P0455 is a vapour leak
