Suddenly had this come up last night. Well, I had an Engine Malfunction warning light come on so I plugged in my Cobb to read the codes and the P0456 came up.

Evaporative Emission System Leak Detected (very small leak)

Input? Car was just sitting in the drive way all day and I had driven it in the morning.

TSB?

TSB = technical service bulletin. Some owners, myself included, had to have the evap cannister replaced because of a leak. I don't recall the numbers of the codes, but there are two: small leak and gross leak. Try tightening your gas cap, clear the code, and see if it stays gone. If so, you are fine for now. If it comes back, or if you get the code for gross leak, you will probably need to have the evap cannister replaced.

So even after replacing the gas cap and clearing the code and you still get it would it be replaced under warranty?
