yeah its on the back of the motor right in the middle of the block. Its kinda hard to see...its a blind shot....If you reach from the intake side of the car around the back of the manifold, you can feel for the connector...you might need to get it from underneath though....i cant remember nissan had a lot of problems with cam and crank sensor on the 4 cylinders...there is actually a tsb for them i think...i can remember i work at infiniti now, but i can check in the service manual tomorrow to find out for sure
