I had the same problem, my car is cali spec, it has this huge swish valve actuator in the way, and that is why I cant see my knock sensor. If you look in front of the intake manifodl you will see two small screws that are grounding the knock sensor (which you cant see) follow these to the right (towards driver side) and then u will see a wire with a connector that has two wires going into it, i think one is brown and one is white on my car. anyway this is the hook up to the knock sensor. if there is a huge round thing off to the left this is the swish valve and its in the way. look at my pic it is circled... my advice... bring it to nissan, if u have the knock they shouldnt charge you more that 150 to install, my local dealer said $130.

good luck,
if yours is the same and you figure out a way to get to it, please tell me as id love to save the $130. Pm me if you have any questions.
