Getting error code P0449 and poor gas mileage (down about 25%)

"EVAP Emission Control System Vent Vlv/Solenoid Malfunction"

Does that mean the solenoid is malfunctioning or it is just tripping the sensor? Where is this solenoid?

2000 Pontiac Grand Prix GT
~96,000
Automatic V6

No serious past engine history.

Can anyone help?

I donated. Thanks in advance.

Ok, so do you think that the solenoid failed or that the sensor just went off and it's something else?

Most likely the solenoid, if the valve is cheap id probably do it just for laughs.
