Here's a link to the specs.

Hello the sensor is located under your intake manifold you will need to remove the intake manifold to gain access to it here is photos of what and where your looking for this

under the lower intake manifold...it is a pain to get to

Your knock sensor is located undernesth the air intake manifold on top of the engine block. This goes for 2000-2004 xterra V6 3.3L models.

You have to take the entire intake manifold off upper and lower. you will find it on the main block after you take the lower manifold off.
