How to replace the knock sensor in a 2000 Nissan Xterra?
I believe the knock sensor is under the intake manifold requiring it's removal. I have not been able to verify this yet.
If that's the case, be prepared to get giggy with this engine. It's not an easy, logical design, so you might want to take care of some things while you're in deep. For example, the manual calls for the timimg belt to be replaced at 120,000 miles (if memory serves) so you may as well tackle that also.
Xterra Haynes manuals are few and far between. I strongly suggest acquiring either the Haynes or a FSM before getting giggy with this engine.
Eureka! We sucessfully did it another way and saved about $500. (est. from a mechanic to replace with me buying the part.) Go through the front of the engine. We were replacing the time belt etc. anyway.... I have photos showing the 'impossible' too.
We were told that the knock sensor wasnt that big a deal that the truck would still be ok if that was not changed. What we did change was the crankshaft position sensor that was bad. But we are still having the same problem as before when the engine gets hot it wants to cuts out. Would the knock cause that sort of problem?
The knock sensor on Nissan 300ZX non-turbo from 1990 thru 1996 is located below the lower intake manifold on the rear of the engine block. To replace the knock sensor the upper and lower intake manifolds need to be removed. It is always best to replace the knock sensor with a new one considering its major dissasembly.
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.
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…
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…
the cam position sensor is part of the distributor and cannot be serviced seperately. i had this problem when the check engine light was on, code says Camshaft Position Sensor is bad and also the code for bad Knock Sensor. these problems makes my 2000 Nissan Xterra stall and created knocking noise, after do some research. i called the dealer, they told me i have to replace to whole new distributor, which cost about $400…
Knock sensor The knock sensor for a 1996 Nissan Altima is located on the backside of the block above the oil filter. But before you go and change it out, run a tank of the best/hightest rated gas you can find and see if that fixes the problem. On my 1995 the Knock sensor is located under the plenum and intake manifold on top of the middle of the block.
The Nissan gurus put the knock sensor on the car for a reason. Unfortunately it uses the engine block for the ground and only one wire of the two in the harness is live. The knock sensor is not the easiest piece of equipment to get to so many people either live with the knock sensor being bad or bypass it. Once you get to the sensor, you can clean the engine block and the…
