P0456, then P0442
Had the SES light on this morning when I started the X. I scanned the code and it came up P0456, small EVAP leak.
I didn't see a thread here dedicated to this code, but poking around in various threads points to a gas cap problem. I'm hoping that's right, I already know where the gas cap is and how to get it off. I did have a Loose Gas Cap come up on the odometer display about a month ago.
I cleared the code this morning, light didn't come back on for the commute, but it's still stored. My first try on keeping the code from coming back is applying a very small amount of grease on the filler neck where the gas cap rubber seal seats.
We shall see...
