P0449 says that the PCM is not seeing the voltage potential it wants to see when the vent valve is off or commanded on. I would suspect it is the Evaporative Emissions (EVAP) Canister Vent Solenoid near or on top of the gas tank is bad. To make sure check the voltage at the pink wire. It should be around 12 volts. If it is low, it may be bad wiring or the PCM, but not likely. if you have 12 volts suspect the solenoid.
