The knock sensor is supposed to detect variations in the sound and vibrations that your engine makes - knocks, in other words. When it notices changes in the noises/sounds, it is supposed to calibrate the engine a bit (timing, maybe?) to compensate for the change. It is basically trying to make some assumptions based on what it is hearing. I also have a Nissan Altima (2000). If you need to replace your knock sensor it is almost impossible to reach without lifting the car up at a service center. Jack stands and jack didn't help me. I let a shop take care of it.
I forgot to mention that it is located underneath and near the rear of your engine. You have to use a pretty small-handled wrench or socket to take it off.
