The PCV is located on the passengers side, or front, of the engine directly behind large alternator mounting ear. You won't be able to see it because it is under a twist on cap that may have a MAF sensor mounted on top of it. It is not necessary to remove the sensor. Just CAREFULLY give the cap a quarter turn and lift off. You may need needle nose pliers to reach the valve. Make sure to check the o-ring. Hope this helps.
