It should be going to your valve cover.
NOTE: On VIN K applications, the Manifold Absolute Pressure (MAP) sensor is mounted to the Positive Crankcase Ventilation (PCV) Valve cover

Open hood, top left side between the valve covers. There is a "funky" plastic housing that turns counter-clockwise (less than 1 inch of travel). then pull straight up to reveal the "missing" pcv valve.

The pcv valve is located under the map sensor in a plastic housing. If you stand on the passenger side of the vehicle and look under the hood, the map sensor is the sensor right in front of you. It should have three wires going to it. If you look closely, the sensor is clipped into a type of cap. If you grab the cap the sensor is clipped into and twist it counterclockwise, it should come off and the pcv valve will be inside. You may need new o-rings to prevent oil consumption. You may also need a needle-nose pliers to remove the sensor from the upper intake manifold.
