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.
Yes, you should always run your vehicle with its Knock sensor.
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.
Under the upper and lower intake manifolds at the back of the engine block.
You have another problem other then the knock sensor if the engine will not start and run. A knock sensor will not cause the engine not to run.
No it will not cause it not to run.
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.
No it will not.
you will have a knock sensor code and the car will run slugish. when a knock sesor code is set its retards the timing so the engine will not detonate. the easyiest way to fix it is relocating the sensor.
newer cars do have knock sensors.. I have a 2001 xterra with the 3.3L v6 and the knock sensor is located underneath the intake manifold.. you might want to get a good repair manual or copy some pages out of one at the local library to help you figure out how to do it yourself if you plan on doing it. I'm about to change mine this weekend after i get some money together for the sensor and new intake gaskets.. this thing is making me go broke!
LS does not have a knock sensor. GSR does have a knock sensor
