Crankshaft Position Sensor (3.0L) On lower front of engine here is the location of the 4 cyl. Check out the images (Below).

If it's a 4 cylinder, it's right on the end of the head on the driver's side. If it's a V6, here is a pic of the location. Install CMP sensor and push sensor downward until it contacts the boss on the cylinder head. While holding the sensor in this position, install and tighten CMP sensor bolt to specification.
