Thanks SO much for showing a picture of the M6-1.0 x 30mm bolt! Can’t believe how many videos of this relocation procedure DON’T SHOW it!!!

Just wanted to say thanks. I watched your video and a few like yours and finally did my relocation and everything went great. I was reluctant to do because of some negative opinions about the relocation. But after 180k miles it made more sense just to relocate it. Thanks to all the first gen xterra you tubers!

Just did this to my Nephew 2003 Nissan Frontier and it worked and was super easy fix. Truck now accelerates, idles and runs better. Thanks for saving us a TON of money and work with a simple relocation!!

Been putting this off for years but using the maxima harness is genius. Thanks!

Can't believe they have it in that location! Such b.s. Thank you so much!

Thanks so much for this video! I bought a 2003 Xterra at a great price recently, and it showed a bad knock sensor. I used the procedure you demonstrate here and it fixed the issue, enabling the truck to pass right through emissions testing. May not be the ideal place to mount the sensor, but at least it is still functional to some degree and it satisfies emissions requirements without having to tear down the entire top of the engine. I took mine a step further, cutting the original sensor wire further to the rear and soldering all wires into a new 2 conductor harness connector in case I ever get to replace the sensor in the stock position.

Doing this for an older friend who have a fixed income this weekend, it was puttering on them a while back and scanned it with the OBDII reader and it came back to be the knock sensor and this weekend it finally gave up on them. Thank you for this.

Cody, you are the Buddah of repair hacks. This saves me so much time and money. I can't turn wrenches like I used to. This saves my cramped fingers and wrists a week of recovery. Thank you so much. So very much! Thank you, thank you.

Hey this worked on my Xterra! Thanks man and for everyone else make sure you buy the part from the dealer or amazon that looks exactly like it.

I did this to my 2000 Xterra after watching this video. The mechanic quoted me $675.49 for the work including parts. The knock sensor only cost about $10 at Autozone and the rest was basically labor. I only ended up spending $20 at Amazon for the sensor, loom, and wire cutters. Thanks for this great advice!!!!

THANKS CAR GUY. JUST RELOCATED KNOCK SENSOR ON A 2003 FRONTIER 3.3 NATURALLY ASPERATED. USED 1997 MAXIMA SENSOR AND HARNESS. WIRED INTO HARNESS RIGHT WHERE YOU SAID AND WORKS GREAT. NO MORE CODE P0327. LANCASTER CA T ND M AUTOMOTIVE

Did the mod as described on my 2004 Xterra. Got my parts from Amazon. It's all happy now. Yes, this is probably not the optimum theoretical location for the knock sensor, but we're talking about an engine who's designers should be flogged. Nice Job on the video!

They sell kits on ebay. New knock sensor and plug in for about $15. I would use butt connector crimps and heat shrink. You are asking for trouble with wire nuts. Also if you have the wire the side of the block or head is a much better location. It picks up valve rattle vibrations.

thanks for the video! saved us a ton of labor and fees! all the other replacement videos were horrible and you down right got it perfect!

My 2003 xterra was misfiring Bad ,got spark and fuel ,new plugs,wires,rotor and cap...no change , had knock sensor code for 11 months.....ignored it....did relocation as you showed..RUNS LIKE NEW ! THANK YOU !!

Thanks for the video. Relocated mine 2 weeks ago. Afterwards I cleared my CEL. Yes I know the knock sensor code doesn't throw the light. But ever since replacing the KS, my CEL has not come back on for my catalytic converter. the po420 code. Could be just a coincidence but nevertheless, I'm a happy guy.

Excellent idea. Gonna do this but solder connections and then use shrink boot over connections. Saves a bunch of $$$$ labor wise friend.

Wanted to say thank you for your video. Being on disability don't have a lot of money for auto repair. Bought the parts and fixed it myself. Again thank you.

So I did this on my 03 xterra super charged.I used a wire harness from a xterra I got at a junkyard.And got a sensor from rock auto.I didn't think it was going to work because I had to bolt the sensor to the supercharger.But it did and I passed emissions Thanks Cody!

I just did this relocate on my 2000 Xterra. Code is gone. 2V reading off the sensor. Timing is back to what it should be and runs way smoother now. Thanks bro.

I thought this was Eric the car guy but either way thanks Cody

Nice video. I thought about the original part location and read some of the comments about the harmonics being further away and I came to this conclusion. That location is only good for piston misfire. The vehicle is ohc so camshaft noise is a no. It's closer to the rear of the engine so the front cylinders would be difficult to pick up misfires. Crap engineering at its finest. They could have placed at least 2 sensors above the plenum. With metal that contacts with the same place as the original part. I did do this because I took the upper plenum off for valve cover gaskets and at the time the sensor was 100 bucks. No way... I would say if you want factory location, go full bore. Valve cover gaskets, knock sensor, fuel injectors and if you can replace the exhaust manifolds, I guarantee one or both have cracks. If you are doing 500 dollar labor, get the most bang for your buck.

Thank you man, I’m going to be doing this today when I get out of work,I have an 02 sc frontier

That engine's other complicated thing is it has a lot of hoses... vacuum, air, and coolant. Specially coolant small hoses that are hidden and difficult to get to

I did mine not 24hrs ago. Light was off for about 50 miles. Now im getting a code for cam shaft position sensor? Or was it crank? Either way...another code that wasnt there before. Any idea? I used a harness and sensor for 95-99 maxima.

I have 04 xterra with p0238 the engine run fine on idle but it feel want to give up on higher rev , my major problem is the car won't engage when I shift the lever I feel it want to engage on D little bit but It won't , my question is what was the symptoms for your car is my transmission not engage is related to the code p0238 knock sensor . B.S I have 1 code only

yes! thank you for this vid it worked and saved me serious $$, great video, stable, crystal clear, well lit, good pace, concise instructions, 5-star, triple A, etc!!

Wire nuts and tape is just asking for trouble later down the road. There's a lot of heat under that hood. Even crimping is not ideal since it relies on a pressure-fit connection. Solder it, use heat-shrink, and don't ever worry about it again.

Hi Cody I re-listened to the video. So you can use a knock sensor that is technically for the maxima like the one you used in this video. I ordered the sensor for the xterra and it didn't fit the harness so I returned and bought the sensor that fits the maxima harness.

I've been told that you do NOT have to connect the shielding wire at all. Just the main wire as the shield does it's job at the other end of the connection No need, just leave it alone

Great tip, did this on my 01 easy peasy

Very well done, thanks for all the good info !

Thanks for the info man, great video and this is gonna save me a ton of time and $$$

Thank's Cody very clean job. Old School

hey cody, I have a 2001 xterra 3.3, I bought the sensor and pigtail to wire into the factory harness, the pigtail that I got was the one they say to buy for this but the two wires coming out of the pigtail was brown and white, which one goes to the grounding and the white wire from the factory harness

Cody, you're mechanical skills saved me a hell of a lot of money. Just relocated the sensor to the upper intake manifold as described in your video, plugged in the reader, cleared the codes, started engine with reader plugged in, now it reads "NO CODES" 2004 Xterra 4WD SE V6, 3.3L. How long to drive it around before smog check? (due this month).Thanks Bud!!!!WLevy

Thank Cody! Clear, simple and informative...they way all instructionals should be. I think that I can save a bundle now with this info.

this same process can be used on a 2000 nissan frontier XE with the 2.4 L engine.

Do I need to take old one off or can I just splice new one to top and cap off old Wires

Hi, great video, is there any risk for the motor relocating the sensor?

Hey Cody - Thanks for putting the time in making this video, and the example of how extensive the work actually is if any viewers want to change the KS in the original spot. ONLY CALL OUT that I've tried to forget but leads me to post my first actual comment on youtube.... Your wiring techniques are BRUTAL. You should be proud of your work, and make it last and if found by the next car owner, not leaving them with "WTF" questioning the instal work. Thats it. Thanks again for the post.

Car guy how about a video on the crank shaft position sensor for the 2000 nissan frontier?

would it be the same for my 2001 nissan xterra xe 3.3l v6 automatic 4wd non supercharged

Which way do I go with the splice?

I think I need help figuring out which wires I need. I cut into the thicker one. It was a coax wire. But there was the shielding, and a black and white wire. Did I cut into the wrong one? It might have been white and red. I’m not at home right now. But it’s been driving me crazy.

so is it safe to assume its okay to just cut the wire and leave the old sensor in its original location and just relocate the new one and splice the wires?

great. thanks Cody. Gonna get it done soon

very informative and clear. awesome video. thank you!

NEVER use wire nuts and electrical tape to hold a critical component. Always use proper sealed connectors with heat shrink to make it water tight!

Welp already replaced one in a customers car by the books wasn’t that terrible honestly just two coolant hoses in the back of the manifold that were a pain everything else is straight forward

We followed your procedure exactly, the amber light is still on. Do we need to clear the code or reset the computer, or do we have nother problem.

Eric the car guys brother 👍 installed easy. Mine came with pigtail on ebay.

Why do we need to use the maximas knock sensor and pigtails. Why not the vehicles original knock sensor and pigtail?

On my 06 Nissan Murano a rat chewed the knock sensor wires clean in half ,I’ve gotten rid of the rat and there seems to be no difference in how the car runs no engine light ,no default mode or anything it runs fine. It’s a low mileage great running car. In your opinion am I doing any damage by leaving it disconnected? Thanks. Brian.

gracias me ayudo mucho

Cody, good work.

No need to cut wire, follow wire to connector , remove pins from connector, connect new harness connector pins to engine harness. (my Xterra wire colors wire were gray wire and white wire) single wire connector to sensor left side, other side pin not used, I senors doesn't work correct, reverse connectors at engine wire harness. May have to modify new connector wire ends ( cut shell away)

Cody you are the real MVP haha Thanks pal!

Thank you, this was very helpful.

I have a 2000 x and can not find the wire, also I see it is routed to the front under the manifold, I see a large wire it is grey with blue streak and I followed the wire going into the fat grey one, there was three wires, blue, black with white stripe and white. HELP PLEASE

Thanks for this. Getting to the old sensor is a bear. We bought a replacement sensor for the Xterra 2001 SE, it comes with a pigtail with 2 wires. Another video said we connect the leftmost connector to the white wire and ignore the 2nd wire on the pigtail. Do you know if that is correct? Does the sensor get a ground from the valve cover? Should we connect the ground sheath to the rightmost connector on the new sensor? Thanks.

The VG sure has plenty of hidden shit attached to it lol

Dumb question: Is that new Knock sensor the one that comes for that 2002 Nissan Xterra or from the 95-99 Nissan maxima? Do they use the same Part Number for the knock sensor?

I would have given the video a thumbs up if you had not used wire nuts in the engine bay... Or anywhere on a car for that matter

Okay,thanks

Working on a 2000 xterra. The only thing I don't see is where the ground wire is in your video. Is it the two wires coming out of that loom?

Great video dude

Thanks for the great tip. After replacement the truck got quitter but the error code still in the reader even though reset the code from the diagnostic reader. Do you have any suggestion?

Really wish i saw this before tearing my intake out RIP

Thank you great job

Awesome video and information bro.

Awww man thank you so much I appreciate it

Idid that but still doing the same thing code is saying knock sencor bank one any suggestions

Awesome. you saved my ass. Thanks a lot.

Will this work on a 2002 Nissan frontier supercharged 3.3L

I had to take the lower plenum off to get to the water outlet underneath it, due to a coolant leak. my question is, if I already have the knock sensor exposed, cant I just relocate it?

will this work on a supercharged 3.3 litre? frontier?

Holy crap, thank you for this video. I'm usually all for doing things like there supposed to be. But after seeing where that little bastard is. I will be cheating 😃

I'm trying to replace the knock sensor on my 2003 Nissan frontier se and I have the wire harness that came with the sensor and both wires are black so my question is which one is power and ground can anyone help with this please

Hi! Great video. My Knock Sensor is shot so I would like to do this to my vehicle. I just wanted to double check that this will work on a 2000 Xterra. And, are you actually leaving the original Knock Sensor where it is in the engine when you do this? And I looked under the hood, and cant quite figure out which wire you spliced into. Thanks!!

Great explication

What year does the harness has to be from a Maxima?

Will the check engine light turn off when you replace the knock sensor or do you have to hook up it to a diagnostic box? thanks

Great video, thanks. May have missed it but why not use a harness and knock sensor for the year and model of the vehicle you are working on instead of a different year Maxima?

Can you do this on a supercharged one

I really want to know so a quick response if possible Cody my good sir. You said you used a maxima sensor.... Is it a sensor for a 2.4L and used for a 3.3L Xterra? It looks identical. The reason I ask is because I ordered the harness from eBay but it doesn't match the part number for the actual Xterra knock sensor, naturally. So can you use that 2.4L knock sensor for the V6 3.3L Xterra?

Just did mine. Instantly the service engine soon light went out. All the codes gone. Several miles later and still no light. Is it my imagine, or does it run slightly better after? Seems like a bit more power in the top end.

Will this work on a 2001 nissan xterra

where is your workshop

Thank you buddy

Why can't the relocated sensor be attached with a new harness, and not a splice

so I watched the video but where to splice into the harness was not shown very clear I need to do this on a 03 Nissan exterra

is it a 99 or 95 sensor you get?

Question. Will this fix my problem with the gas mileage and the lost power or is just fix the engine code light?

Cody the wire black and white is that the one that goes to the crankshaft position sensor??

Will this work on a Nissan Frontier ?

Would this solve a knock sensor not resetting for smog check?

I bought a knock sensor and harness of ray 99 Pathfinder from AM Autoparts. Under $20.00 Anyway, I followed your instructions exactly and everything went well. I am hoping I will be able to get a reading off my Fixd Sensor that I bought. Is there a reset period before the sensor will work again?

Hi car guy thanks for the videos you make have question about the knock sensor relocation of 04 xterra ???The relocation of knock sensor have the same function for the engine or work different???? Thanks car guy appreciate you help and time
