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!

Will a knock sensor stop a Nissan Xterra from runing?
no, it would be a problem if you had the supercharged engine in which case you should change it right away. if you have a non supercharged engine do not worry about as it will not affect you. unless you need to pass an emission test.
How do you relocate of knock sensor Nissan 2004 Xterra?
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.
Will your Xterra run if the knock sensor is out?
Yes

What kind of gasoline for Nissan Xterra?
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.
Where is a knock sensor on a gmc sierra 1500?
the knock sensors are located in the top of the engine block. The intake has to be removed to get to the sensors.
What is the knock sensors function?
Knock sensors detect abnormal vibrations in the engine. The system is designed to reduce spark knock during periods of heavy detonation. Knock sensors produce AC output voltage which increases with the severity of the knock. The signal is fed into the PCM and the timing is retarded to compensate for the severe detonation.
How change knock sensor of Chevy Avalanche?
In order to change either or both of the Knock Sensors, you must first remove the wire connections. The sensors are physically located directly underneath the intake plenum. You will need a metal tool to remove the fuel lines also. Needle nose pliers may be needed to extract them. You will need to use some sort of sealant on the new sensors.
Where is the knock sensor found in a 2000 Nissan Xterra 6 cylinder?
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.
