Question about 2002 Nissan Maxima
Take the drive belt off and see if the noise goes away. This will eliminate anything outside the motor. Maybe, if this motor is a four cylinder, it may have a counterbalance shaft that is not properly synced because the chain or drive belt is worn or not indexed properly. Also, it could be a loose crankshaft pulley!

The best way is to use a scan tool to clear the codes, that will turn off the light, also disconnecting the battery over night may work, but no completely sure about that, it varies from year to year.

The knock sensor is a major pain in the a..s to change I would suggest taking it to a reputable shop for a second opinion to see if they realy performed the work. Also with OBD11 (2) diagnostics if you have multiple misfires its not the wires its something else, also if you got a code for a misfire it would be specific as to which cylinder is misfiring. My best guess would be to get your coil checked.

Testimonial: "Excellent "
If the car is pinging you will set a knock sensor code.'
This comes from bad gas and running lean., You really need this professionally inspected to rule out the basics. I have seen alot of nissans with the knock sensor code stored but the light is still off.
Fill up the tank with high octane chevron and some techron injector cleaner and clear the light. If it stays off for a couple days then go get it inspected. Even if the code is stored it will still pass as long as the light is still off and the monitors have run.
