The idle air control valve is located on the back of the throttle body. It has an oval electrical connector and two torx screws holding it in. Unplug the connector, remove the two screws then lightly tap the body with a soft faced mallet to loosen it from the body.
Once you have it out and prior to installing a new valve clean the seat inside the throttle body where the idle control fits. This must be very clean! Installation is in the reverse order.
To save some cash, pull the valve out and clean it with throttle body cleaner, this usually fixes the problem for quite a while.
Good luck and hope this helps.

SOURCE: location of knock sensor
Knock sensors can be difficult to locate because there usually buried under intake or exhaust manifolds and misc. engine wiring and plumbing. Knock sensors need to hear an engine knocking noise, therefore there usually located somewhere they can hear an engine knock. If it's a V6 then possibly it will be between the cylinder heads and access to them can only be attained by removing the intake manifold. I would suggest calling a Nissan Dealer parts person and ask them. Good luck.

If it's not idling and has problems starting, it's probably the IAC motor. It's located on the throttle body. Follow the airfilter box all the way to the engine, where the rubber flex hose attaches. The throttle body should be the first aluminum part you come to. Attached to the side you'll find small little aluminum part with a small wire harness attached. Unplug it, take the IAC motor off and clean inside with carb cleaner. This should fix the problem with the idle.
