past few days, I am getting orange engine light...I checked with on-off way...It's code p0456. What should I do to fix it??? Any recommendations.

 

That's the small evep leak I think. I have the exact same thing on mine. I have no idea what it is but to fix it they'll have to run a smoke test on your car. The guy at the shop said it's probably about the size of a pin hole andwouldn't be worth the money to fix it since it isn't really causing any problems. Here is a site that may help though.

It isn't official but it's the same thing everyone else has been telling me so I'd go with it.
I live on a steep hill so I think that's what's causing mine. Possibly the same for you.

replaced the gas cap and reset the code. light still comes on
