A knock sensor is located in a specific area on the block or cylinder head in order to sense spark knock occuring and send a signal to the ECM to retard the timing. Relocating the knock sensor would defeat its purpose.
Th knock sensor on a 2002 Nissan Xterra 3.3 is located on the top of the engine. It is mounted under the engine intake.
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. Hope this helps.
Under the upper and lower intake manifolds at the back of the engine block.
Yes
V6 3.3L The sensor is located underneath the air intake manifold on top of the engine block. This should take an experienced mechanic about 3-4 hours to replace.
The knock sensor is located below the intake manifold

All 3.3 supercharged FI MFI Xterra's require premium gasoline. --- running on regular or ethanol will probably trigger the Xterra's knock sensor in this engine. Since replacing the knock sensor (code 324 or related) in the Xterra supercharged engine is extremely expensive (figure $650-$750) depending on year and location... --- use premium. The "non aspirated" 3.3 cylinder Xterra can use regular gasoline IMO.... --- personally, I would try to avoid ethanol blends (10%) since the Xterra engines are somewhat sensitive to lower grade fuels.
it is underneath the lower intake in the middle of the "valley" on V6 models. between the cylinder heads on the block. pretty big job. the knock sensor WILL NOT turn the check engine light on. it will store a code but NOT turn the light on. (i am a Nissan tech, trust me) it will effect the timing and fuel strategy though.

where is it located
You can find a 1996 Nissan Pathfinder knock sensor picture in most auto repair manuals. Most Nissan dealerships repair centers will provide you with a picture of the sensor.
