What does a code p0455 mean in a Ford Taurus?

It's a 1998.

The code is for an evaporation leak in the exhaust system. It is not a serious problem but it could cause bad mileage.

Evaporative Emission Control System Leak Detected(Gross Leak). You either have a crack in your gas cap, or a leak in your gas cap seal. I suggest buying a new gas cap just to be safe.

This indicates a leak in the Evaporative Control System caused by a faulty or leaking gas cap resulting in low gas mileage because the fuel is evaporating.
