I'm means you have a leak in the evaporative emissions system. Most likely you have a loose/defective fuel cap or a bad hose.

The Evaporative emmisions system is designed to burn the fuel vapors from the fuel tank instead of releasing them into the atmosphere. The system consists of a Vapor management valve, Fuel tank pressure transducer, vapor management canister, and canister purge solenoid. The PCM monitors system pressure throughout drive cycles. If the system indicates low pressure from the FTP for three consecutive cycles, the check engine light is illuminated. Usually a code P0443/0444/0445. Depending on the size of the leak. Most likely causes are a loose gas cap(Or defective seal), defective purge solenoid(CPS), Faulty Fuel Tank Pressure Transducer(FTP),or sticking Vapor Management Valve(VMV)(The valve that releases vapors to the intake maifold for combustion). Check your gas cap fitment and roadtest the vehicle at a steady 45mph for atleast 15 minutes. If the light goes back off you know that was it. If not, you will have to take it to the dealer so they can perform a proper EVAP system diagnosis....
