Remove the engine cover. As you face the engine, you see the black composite upper intake manifold? Look to the far left of it. There'* a black cover with your MAP sensor. It turns to unlock. The pcv is inside. Pay VERY close attention to the o-rings, and make sure they go back in correctly with the new valve.
