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.
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.
Under the upper and lower intake manifolds at the back of the engine block.
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.

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.
To change the knock sensor on a 2004 Nissan Xterra, first disconnect the battery and remove the intake manifold for better access. Locate the knock sensor, which is typically positioned on the engine block, and disconnect the wiring harness. Unscrew the old sensor using a socket wrench, then install the new sensor, ensuring it's properly secured. Finally, reconnect the wiring harness, reassemble the intake manifold, and reconnect the battery.
