1998 Buick Regal 6 cyl Front Wheel Drive Automatic

I recieve this code when I checked my obd system. The code tells me it's a Evaporative emmissions contol system pressure sensor high voltage. I have already replaced the MAF, and front O2 sensor. Is this code telling me the O2 after the resinator is defective?

the car runs great rpm's are normal at idle and while driving. No misfire. Though it does seem to eat more fuel more than normal.
Thanks for your help!!
