My code reader came up with P1456 on my 2002 Altima 3.5. Could not find the definition. Please help....

Looks like you have an EVAP Very Small Leak.

Check the fuel filler cap first, make sure it's tight (3 clicks minimum when tightening it, I'm sure you know that) and also make sure it's a Nissan filler cap. A lot of folks have been using the lockable caps lately, and they just don't seal enough to pass the leak tests.

If that doesn't work, then a dealer, or another reputable shop, will be able track down the leak.
