Re: engine code help

I believe code 456 is "A small leak has been detected in the evaporative system".
Perhaps someone will chime in and confirm or correct this.

If it is a small leak in the evaporative system, the fix might be as simple as making sure the gas cap is on tight. The second suggestion is to inspect the vacuum hoses attached to the purge canister for holes or split ends.
