The engineer who placed the sensor in the original location deserves a firing squad!
Jonny, great vid. I used your advice and a scope to identify the knock sensor on my 2000 Nissan Froteir. Then used a 40" screwdriver with a slight bend towards the tip. Then slid the screwdriver over the top of the tranny and under the sensor, then a little twist to break the sensor and pulled it out from the top. The connector was fried, literarily melted into the sensor. Thanks a million for the vid. I was just about to start pulling the intake when I looked on youtube and found your simple step procedure.
Need to do this on a 03 4x4 frontier. Was it really hard.
What items did you buy, parts wise
Thanks
I bought the knock sensor off of ebay, you can go to Amazon, or your local parts store. The tool that made it all possible is my bore scope, so I could see under the intake while easing my screwdriver in place.
Thanks for making this video. A mechanic charged me 4 hours of labor cause he couldn't get to it.
Shame on that mechanic for wanting
to do a job properly, technicians can't just cut corners like this, because when it causes major engine damage, you will come back and say, "look what you did to my engine"!
This is a hack RUclips shade tree, you get a lot of views for making the light go away easy. Why don't you get yourself a peice of black tape and stick over the light.
Man your method is easily the fastest I've seen
I have a 2004 Nissan xterra 3.3li
I need to replace mine, although I only have about 83k only.
I love your method/approach, I really don't like splitting the wires, I think your way is more professional.
I only hope there won't be too many variables on my 2004, you made it look easy.
I really appreciate your video😊
Thanks Jonny
Awesome! Thank you, this is a more ideal way of doing it in my mind.
I DID THE REWIRE METHOD WIT A 97 MAXIMA SENSOR AND HARNESS. WORKS GOOD. HOWEVER THE DORMAN HARNESS DOES NOT COME WITH THE GROUND ALL THE WAY THROUGH, SO I HAD TO SPLIT AND CUT ONE END OFF AND SPLICE ANOTHER PIGTAIL ANYWAY. LOL
Is this the same for a 2002 V6 Nissan frontier XE ?
Just bought a 2003 frontier,it's giving me the knock sensor code,I'm going to try your method to install the new KS. Thanks for video.
Don't do it. It's a bad idea. Trust me. Take the time and mount it in the proper location as the ECU is calibrated to a certain signal strength that it will not see with the knock sensor sitting on the manifold.
I'm replacing it the right way, on a 2002 dessert runner v6 it has 214,000 on it. This was F'n engineered to be a pain in the Ass ! Plastic will only take so many heat cycles before failure. This was planed by Nissan for the dealers to make $$$ on service on this crap !
Planned obsolescence is real.
I concur wholeheartedly
Excellent tutorial. First I've seen to access the Knock Sensor from the underside on an R50. A great DIY hack IF you have the equipment, as he says.
Thousand Dollar Job done for 25 cents. Well done
Excellent video good job.
Now....if I only had a lift, damn!
awesome video, I'm going to give this a try on my 02 xterra….
Just splice the wire so much easier and functions perfectly
And changes to a low octane map and drops horsepower lol, not that hard of a job to fix.
Will this method apply to a Nissan 2003 frontier ?
It's very important to torque the knock sensor on every vehicle . I've seen come back knock codes because of lack of torquing the sensor . Very common on the Chevy 4.8. 5.3 6.0 for not torquing it down . I fixed one on one of the techs that I work with 2000 Chevy 1500 4.8 lt . It was to tight .
Excellent bro, blessings to you. Joey
hey man thats a good idea, can i relocate my 2005 kia optima knock sensor bank 1 sensor 1 ? where is located ?
Totally, bad ass. You rock!!!!
Great video! Thank you!
really hard to do with 4x4 3 hours later still working on it!!
Have you ever done a 2008 Nissan quest Knock sensor and if so do you have a video of that? Or can you recommend a good video or page to check out how to do it?
or you can buy a maxima harness and intercept the wires to to old sensor is way easier I did mine almost 5 years ago this is way too
much work and I don't have a lift
Tell me more
Whohoo! Awsome.
Will this apply to the 3.5l engine as well
JEEZUZ CRIST WHY DID YOUR INTRO HAVE TO BE SO LOUD. RIP MY EARS
Gracias Johnny good video amigo
I have a 2000 pathfinder would this work for me I thaught I had to take the head off to get to the knock sensor
What size (length) bolt do I need ??
I have a 94 Nissan d21 v6 3.0 would this method work on my truck
I'm struggling with my 04 nissan quest. will this all hopefully, help?
Hi,I been trying to find but no luck,went to junk yard found one the same as the one you were showing on the video same year and color ,I even took off the the top part of themanafold and still could not find, buy chance do u live near LA Calif ?
For the 2003 supercharged xterra, could you still replace the knock sensor like this and put it back without relocating it? Or would that be too difficult?
Good Job, Thank You!
please do a video the Nissan 3.3l tps ?
Is this method recommended for the supercharged engine? And if so, where do you remount? Great video, thanks for posting
It's not recommended for the supercharged version as it has a higher chance of knock. I have a very early video where I replace it the traditional way on a supercharged model.
It's knock recommended for any engine because by the time it picks up knock in an intake plenum. It's too late.
i was able to unplug the clip, but the knock sensor broke off the end. but i still have the original harness part. i can just order another knock sensor and it will plug into it right??? does it have to be the OEM? or can an aftermarket one from Orielly's auto parts work???
i have 02 frontier super charged 2wd , do you think your method might work for relocation maybe not same spot
Jonny thank you for the great videos, my question is I am watching Nissan V6 knock sensor replacementyou are working on 1998 V6 pathfinder, I have a 2000 v6 Frontier is the Knock sensor located in the same place and will your Nissan speedy V6 knock sensor work for me ?????
I did this on a 2004 Nissan XTerra 2wd non supercharged, nevertheless, the knock sensor should be located in the same general area.
thank you for replying back, and your awesome education( sharing your knowledge) always appreciated wish me luck lets hope thats all it is and convenicing a shop to watch video do the procedure shown on video..
@@JonnyBarajas I need a knock sensor for a 1993 Pathfinder SE, would this way work too ???
Is it the same as a Nissan Quest?
I did this relocation on my 2000 nissan Xterra in 2014,had 0 problems since.same engine (VG33E).its fine i promise do the relocation
Excuse me Chad. Im having the same problem on my Xterra. Did you buy a new harness or an old one from junk yard.
Kory Johnson i got the part from the junkyard,should work just fine for you too
Chad Warden hey Chad is everything still working ok ? I have the same yr Model XTERRA as you, , I'm going to have to replace mine Thanks Rex
Rex Wilson yeah man, legit havent had any problems.just follow the video closely good luck.any questions let me know!
Chad Warden Thank You Brother Have A Merry Christmas !
Thanks
Johnny I have a 2004 Nissan Frontier v6 no turbo I would like to know if this method will work for me same way you did on the Nissan pathfinder please let me know the motor on The Pathfinder looks just like the Nissan frontier 2004 .
Yep, it's the same engine. I did this on an Xtrerra in fact.
Can you relocate the knock sensor on the supercharged 3.3?
thank you car doctor
Thank you sir
I wish I had someone to do this for me. They did bypass for me the other way and it has caused it to pop codes since for other sensors.
That is actually the crankshaft position sensor. The knock sensor is located beneath the intake manifold. Took me better part of a day on my 00 Frontier SE Desert Runner 2x4 v6
+Michael Kirby Yeah really. I knew something was odd when I looked at the video length and it was under 45min long. What a pain in the ass to replace that knock sensor!!!
This is the knock sensor. Do your reasearch
I own the 2000 Nissan frontier dessert runner SE 2x4 5 speed manual going on 6 years now 177000 miles. Trust me when I say I know the truck. That's the position sensor I've changed it 3 times now first time was when I dropped the bell housing and transmission doing cluch and broke it without realising what it was. I broke it again during insulation and ended up doing this exact same operation to replace it for good
+Michael Kirby What I replaced in this video is the knock Sensor. This fixed my knock sensor check engine light, so it couldn't have been any other sensor. I knew exactly where the sensor was located without actually seeing it, because I had already done it the hard way; ruclips.net/video/xlppV7MK9KQ/видео.html
This is the knock sensor, this knock sensor is beneath the intake manifold he just found a shortcut to getting around having to take everything apart for half a day just to get to that fucking thing.
Very good video Master; will it work on 2001 frontier? looks pretty much the same.. thanks..
yes, you can do this method.
I have a 2002 Frontier with the 3.3. My knock sensor is located under the lower intake manifold. Was this one in the same location? That seemed way too easy. not sure if I will get notified if you answer, please email me at rstorey.shelter@gmail.com
Yes, its the same location.
Wonder if i can unplug it if raise up just the upper intake its too hard to get at on frontier
Will this work for 2001 Xterra
Great Idea...
If you place de sensor right there work s??? So why you remove de trans bridge for i don't understand nothing im a confused someone explain what happened here
thank
Is it legal to relocate the knock sensor. will it pass the smog inspection?
Yes it will pass. If a good knock sensor is plugged in the PCM has no reason to through a CEL for a faulty knock sensor. It doesn't even have to be bolted to anything. You could literally zip tie it to a harness and call it a day. That's pretty much what he should have done in this video since he rendered the sensor useless anyway, moving it to the plenum like that.
YOU CAN GET KNOCK SENSOR WITH THE HARNESS
Can I do this on a Nissan exterra 04 ?
smart dude
i have a 2001 nissan nightmare frontier sc my knock sensor sits under the supercharger now my crankshaft sensor in on the bell housing
Will this work on a 4x4 manual 2002 frontier?
yes
Knock sensor work`s as microfone, recording knok`s in cilinder`s and correcting ignition. You should not do like that. Ignition is goes bad, and you will burn out pistons.
Анатолий Левша ih bvb
Is it possible to unbolt the knock sensor using this method, remove it and put a new one in the same location?
+Mike E I made just enough space to reach in and break the old one off, I would not recommend it, only reason being that there is very little space to carefully replace the sensor back in its original place. If you can reach in and carefully place the knock sensor, i'd say go right ahead. This method is used primarily to re-route and not to replace.
You dont have video for remplace knock sensor on 95/99 nissan maxima bro. Dime como hacerlo bro
Hi, it is necessary replace the harness or I'm fine just with the sensor?
This method saves the factory harness and only replace the sensor
Coo awesome
I live in Phoenix. How much do you charge for knock sensor replacement and/or relocation?
+Taryl Jones These are all dealer vehicles, don't really do work for the public.
Of course you would be doing the easy one.
Buen concelo gracia
you think this really works because what i understand goes in the engine block
Mounting knock sensor to the engine block. block not the intake mounting bolting to the engine block
Nice
Hello, where are you located ? Thank you,
not that easy on a 4wd. gave up and had to do it the long way
If I relocated the knock sensor like in the video , is this going to work like the original location?
Roberto Castellon hola Roberto tengo una xterra 2003 4x4 automático es la misma posición para mi carro asme saber xfavor gracias ?
The short answer is NO! I'm a tuner and recalibrate knock control systems all the time and can give you the long answer if you want.
Didn't work .... I could not fit my hand in even after blocking and ratchet strap to pull it down .... going with the splicing method I guess
I have a frontier 2000, 3.3, Is it the same engine?
Antonio Sanchez yes, it's the same engine.
Will this work on the 04 nissna frontier I'm fairly certain everything is the same
yes
will it work on 4wd model? I can't find the sensor
they're in the same position in the 4wd model. it's in between the block and the intake manifold near the firewall.
Have you done this on a 4x4 with all the additional hardware to deal with- transfer case front drive shaft, front differential? It looks more challenging so just curious if you've done it to a 4x4 Nissan. Thanks!
You have to do it right and remove the intake manifold
@@thumper9226 no you don't, you purchase the KS for a 98 maxima with the harness then splice into original wire and relocate, very easy everything is right on top
For anyone watching this, this pretty much won't work on the 4x4, you'll spend 4 hours messing around trying to get it with the transfer case and front driveshaft in the way, which is the same amount of time to do it the normal way
I thought they said the knock sensor was under the manifold?? I have a 2000 Nissan frontier 3.3 v6. motor looks the same as that one. I have the knock sensor code popping up. where are you located???
Raul Romo it is under the manifold, in this video I took a shortcut, but check out this other video it the same general idea, but with the supercharged edition. ruclips.net/video/xlppV7MK9KQ/видео.html
how did you even get your hands under the manifold? or did you just yank on the wiring and relocate?
Raul Romo I had to unscrew the transmission bracket to lower the transmission and reach from below, but I knew exactly where the knock sensor was, because you can't see it. So I just had to reach in and push down the connector and pull it off leaving the knock sensor there. I got it easy because the knock sensor was the original and it was all brittle and the end just broke off. That way i could just use the oem connector on the relocated knock sensor.
I seen that you did that. I just didn't think you could reach it from under there, since its under the manifold. so you can reach with skinny fingers..lol. my knock sensor is throwing a code, and its irritating. I want to fix it, relocate, just get rid of the that code. where is your business?
my bad ..you said phoenix.. damn I am in san diego
I have 2003 Nissan extra ex can I relocate knock sensor ? The engine got a run the same ? Please help me , ( thanks )
it's the same engine, it is possible.
Is the knock sensor in the same place on a 2004 Frontier 3.3L V6?
The knock sensor is in the same location.
Hi, I have a multiple cylinder misfire on my 1996 Nissan Pathfinder, will replacing the knock sensor fix this issue as well? Knock sensor code comes up. Thanks.
+Shane Sauers I would recommend troubleshooting the basics for a misfire code, which are; fuel delivery, piston compression, and spark. Check those before, usually the misfire of all pistons sets off the code ,and not necessarily the Knock Sensor being "bad".
+The Car Doctor | AB Auto Sales I did an entire tune up. engine shakes pretty hard. I am replacing the knock sensor today by splicing wires on top of the engine and placing my knock sensor on top of the engine as well. also going to replace fuel filter. fingers crossed I'll let u know how it goes.
+Shane Sauers I think I have the same problem on my infiniti qx4. Did the knock sensor replacement fix the misfire?
It ended up being my timing belt tensioner loosing it's ball barings. Replaced timing belt and relocated the knock sensor. Fixed.
now if I only could only see it
Badass
i have a 00 nissan frontier 4x4 knock sensor same way
i have a 00 nissan frontier 4x4 knock sensor same way
Well this work for a 01 xterra?
yes
What if it has the 4 wheel drive option?
I doubt this method would be easy with a 4x4, the method I mean. But if your Nissan is 270 plus thousand miles valve cover and intake components and cleaning are a good idea anyway
Just relocate the sensor
I would not recommend doing this. Knock sensor controls timing. Be hard to pick up spark knock all the way ontop of the intake and would be inaccurate. Can cause engine damnage. Just because the code clears does not mean its a proper fix.
dustin mceachern I always been told the know sensor is there to detect knock and and adjust if the engine ever knocks , I don't believe that sensor is actively adjusting timming .
tiz tiz, Dustin is actually correct. This is a really bad idea and I would not recommend this to anyone. I'm a tuner and calibrate OEM knock detection systems to engines that are modified all the time. The knock sensor is a transducer (microphone). The ECU is calibrated to look out for a specific sound frequency and amplitude (signal strength) that a knock event makes. There are many moving parts in an engine that can end up making sounds close to or sometimes matching the "knock" frequency. But just like I mentioned the ECU looks at frequency AND amplitude. When the OEM calibrates the knock detection system, they run the engine in a no knock condition and measure the amplitude of the noise the engine makes as RPM increases. Once they have a no knock amplitude baseline, they program that baseline in the ECU and tell it to ignore frequencies below this baseline. So when ever the ECU sees a knock frequency above that baseline, it knows that there is a real knock event and not a normal noise of the engine. The ECU then pulls ignition timing in proportion to the intensity of the knock. Typically 2 to 3 degrees is all it takes to stop knock.
Hopefully you can see now how moving the knock sensor from the it's location on the block and moving it to the intake manifold is a bad idea. The knock sensor gets a strong, clear knock signal on the block. But when you move it on the intake manifold, the signal is a lot weaker. And since the ECU is expecting a signal of a certain strength, the engine could be knocking and the ECU wont know it. And if the ECU does detect knock, instead of pulling the appropriate amount of timing to properly deal with that knock event, it may only pull the minimum thinking its ok when in reality the engine is still knocking. And I disagree with the car doctor. It is just as critical to put the knock sensor in the proper location on the N/A models as the Supercharged models for the simple fact the owner of the N/A model is more than likely using 87 octane which is far more prone to knock than premium fuel. Hope this clears things up.
Seems Johnny is a hack, giving the rest of us techs a bad name.
well i did this on mine at about 80K miles on the odometer , now i am at 236,000 miles.... i wonder if i i just did 156,000 miles of damage on my engine. i was hoping to get to 300K on a never rebuilt engine, i guess i might not make it to it.
erik cruz, thanks for the detailed explanation. I was thinking along the same lines, but Im not an expert. Is there a possibility the KS could pick up *more* knock, ie noise it thinks is knock? I imagine so.
In Jonny's defense, no this is definitely not the proper or optimal fix, but I think lots of ppl have done this on NA engines with little ill effect.
Hola amigo adonde vives para q me hagas ese trabajo
Vives en Los angeles por casualidad
Good luck passing smog doing this.
holly smog It passed emissions right after that, as long as there is no check engine light, vehicles 96+ pass emissions here in Az.
Good luck passing CALIFORNIA smog then....
I dont see why it wouldnt pass smog in cali either, check engine light doesnt trigger after this fix.
This guys just hating
I really need help. Do you have contact information?
I have a 99 mercury villager knock sensor bypass method with video uploaded that gets positive comments. It worked great for me plus its not on the manifold--its bolted dead solid to the block. In the comments below several people speak correctly that to go in for a $15--not $50 knock sensor and get screwed and shoddy work that you dont know what happened is only for the fat cats that write checks for thousands and dont give a damn. I read the science below from a scientist but keep in mind it retards the timing RARELY yet it messes up and gives extraneous codes and other things. The shops (career criminals--HUGEST national ripoff ever done on the public--national guard should go in place temp mechanics and shut down the entire corrupt industry nationwide--put on trial immediately virtually all mechanics) HAVE A FIELD DAY--you go in and once its up on blocks then its "WE FOUND THIS--WE FOUND THAT--NEED $2000 MORE IF YOU WANT CAR BACK" Some say 4--$500 to replace the knock sensor NO WAY--what that means is WE WANT $500 TO GET OUR HANDS ON YOUR CAR--YOU SIGN AND WE OWN IT TILL YOU PAY THE AMOUNT WE WANT.
All right. You are absolutely right. This is in all countries. Marketers "rule".
Can someone tell me if this will work on a 2001 nissan frontier v6.
As long as it has a 3.3L engine
Do you live in NJ? I'd rather pay you than pay meineke 400+ LMAO
I'm in Az
And now this car has zero function on it's knock sensor.
Wrong, knock sensor still reads correctly did it over two years ago zero codes, runs perfect,
@@josh65hend There is no way. I'm absolutely sure it reads no knocks, because it couldn't read one, if it happened. Believe it or not, your not more intelligent than the engineers that made the engine management system. While relocating the sensor is a logical and inexpensive solution, to do so correctly would require that you used a scan tool to induce a knock, and confirmed that the sensor read it correctly, and repeatably. Oh, and remember....spark knock can occur without being detected by human hearing. You can guarantee that if the owner runs 87, and drives hard....engine life IS being subtracted. Of course, no diag was done to see if the vehicle was indeed spark knocking due to a weak coil, old or incorrect plugs, bad gas, weak coil condenser, poor engine ground, weak alternator, bad battery terminals, or corrosion on harness pins. This is a ghetto fix, and it serves only to get the vehicle through inspection, it doesn't FIX ANYTHING.
@@whozaskin3639 crazy I did it 130k now have 190k and still no issues, I know people in my camera group how have even put more miles on it, and trucks are running with zero issues, but Yah believe what you wish
@@josh65hend the vehicle did not have a knock induced to confirm a correct reading on the relocated sensor. When a fact is indisputable, it becomes less about "believing" and more about denial of reality. The reality is that this knock sensor hack could get you in trouble, especially on smaller, harder working engines, and definitely on any vehicle running an aggressive tune....or heaven forbid...boost/nitrous. Spark knock can get pretty expensive.
Don't fall for this stupidity!!! He has to break clips??? RED FLAG written all over this video. I worked for Nissan. This is not a hard job to do correctly!! Only takes 4-6 hours for the knock sensor along with a new timing belt and water pump. You might as well replace plugs also at the same time. Do all these at the same time so you don't have to take the vehicle out of service multiple times. The parts should cost less than $500 so do it right and all at once.
