Under the intake manifold in the valley between the cylinder heads
SOURCE: where is the knock sensor located in a 2000 nissan
For Maxima, the Knock Sensor ( KS )is installed in the top, center
of the engine block. Access can be gained by removing the intake
manifold.
Hope this help to solve it (remember rated this help).

Your knock sensor is located Under the hood, center, front engine area, below intake
manifold, mounted on block.
A defective knock sensor may cause engine detonation or reduced
spark advance and fuel economy. When a knock sensor is removed and
replaced, the sensor must be tightened to its specified torque. If the
knock sensor is installed tighter than it should be, it may become too
sensitive and provide an excessively high voltage signal, resulting in
more spark ****** than required. When the knock sensor is installed
looser than it should be, the knock sensor signal will be lower than
normal, resulting in engine detonation.
To replace the 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.

WHEN YOU STAND ON THE FRONT OF THE CAR YOU ONE IS RIGHT BELOW OF THE INTAKE WHICH IS BANK 2 OR THE ONE CLOSE TO FIREWALL , BANK 1 ONE IS ON SAME SIDE NEXT TO THE RADIATOR BUT THEY BOTH ON THE CAM RIGHT SIDE OF THE ENGINE, THE EASIEST WAY TO IDENTIFY THEM IS THAT THEIR CONNECTOR IS GREEN, ONCE YOU LOCATE THEM THE CLIP NEEDS TO BE PUSHED DOWN TOWARD THE SENSOR FOR THE CONNECTOR TO BE RELEASED, ONCE YOU REMOVE THE CONNECTOR THERE WILL BE ONLY A 10MM SCREW HOLDING THE SENSOR PULL IT OUT , THE SAME SETTING THE NEW ONE PUSH IT ALL THE WAY IN , THIGHT THE 10MM SCREW, CONNECT IT BACK AND YOU'RE DONE,BUT FOR THE ONE ON THE BACK SOMETIMES MIGHT BE NECESARY FOR YOU TO TAKE THE INTAKE OFF....HOPEFULLY IS NOT YOUR CASE....
Good luck!!! and if you need the crank for hard starting on hot/warm, it is located on the botton middle section on the transmission is the only cable that goes down to a small piece of metal and it is held by a 10mm screw only to protect the sensor, you will se the sensor once you remove that small about 6-8 inches piece of metal. Then you'll be able to unescrew the 10mm screw that holds the crank position sensor. when you pull it off you'll be able to see the fly wheel inside the transmission...
you all enjoy your rides out htere!!!
