All it has is this hose to where one normally would be. Rock Auto and other parts stores list an actual PCV valve for it. Didn't find anything online about this for Grand Am but in the S10 forums some have said their trucks don't have one either.

1 - Many vehicles use a calibrated orifice instead of a true mechanical "valve".
2 - Sometimes when you replace a true mechanical PCV valve, the new part is a hollow piece with a calibrated orifice instead.
