Save $2,000+ in repairs with this unique knock sensor relocation plug n' play method which eliminates the need to splice or cut any wires.
Tips:
-try this method before cutting into the wire harness. It will save you time, money, and will be a cleaner looking repair. Not only will you have a better long-term electrical connection, but it will also make it more likely to pass inspection during a smog test
-buy an aftermarket sensor (you will save $270+ vs. buying it from the dealer)
-tie a string/rope to the electrical connector after unplugging it. This will make it easier to fish out the wire harness in order for it to be long enough to reach the new location
-make sure to find a longer 10mm bolt and have it on hand or else your won't be able to finish this in one shot
This is for vehicles with the common 3.3L V6 JDM VG33E engine such as the 96-04 Nissan Xterra, Nissan Frontier, and Nissan Pathfinder.

You sir just saved me from not using my car this winter

@Fjern32 Год назад

Worked great! Mine did not break off like his did but used a tiny screwdriver to snap the fitting on the top. You can see it with a well placed flashlight. Thanks👍

Thanks man I'll try this as soon as it warms up a bit 😎👊Great video brother

Thank you for your great help! I'm going to be doing this on a 2003 Xterra as soon as it comes in, had to do crankshaft sensor last week and messed up the wires for knock sensor unfortunately

Yes, i believe the knock sensor is in the same location on the SC model

@A86140 2 года назад

My hands were way too meaty to be able to do this and my frustration I gave it a big tug then, snapped clean off! I guess I'm lucky I got an Arizona X and the connector was brittle enough to do it, but all I had to do was pop off what was left off the old knock sensor, plug in my new one, then bolt it down! No code!

Captains log. 40 minutes in, my hand has undergone some serious conditioning and I’m just barely starting to feel the tippy tip of the knock sensor wiring connector. So close! Taking a lil break now. PSA- that coolant pipe you use as your landmark is friggin hot, my engines been off for two hours and it’s still burnin my hand

@aaronwism Год назад

It only took 6 hours also! 😂

@raiderman28 Год назад

i wanted to replace my legit, but i was afraid that a bolt would break, or a screw would strip. but i think i might be going back to do it the right way, since i have to replace an injector, and might end up replacing all of them, plus the valve cover gaskets. i would be almost there to replace the knock sensor. time is my only issue at this point.

@ronaldreagan388 Год назад

@@raiderman28 yeah, the bolts that hold the manifold are the ones to be careful for, if you can't go to a junkyard and get you extra bolts and you get to see how they feel when taking them off. For the injectors make sure you don't loose the washers and spacers where the bolts are at.

@cowardlycoyote2864 3 года назад

What are the results after replacing/relocating the knock sensor? Also I know you Bought an aftermarket knock sensor but was it stated to be for the 3.3? Some have used a knock sensor for a 4 cylinder maxima. If yours worked could you add a link for it in your description?

@diycast6914 3 года назад

It cleared my Check Engine Knock Sensor code. And yes it stated the the knock sensor fits the 3.3L VG33E engine. Here is the link for the one I got: www.amazon.com/gp/aw/d/B00P1DFWJK?psc=1&ref=ppx_pop_mob_b_asin_title

Can’t remember where i bought mines, but i did relocate it and it worked great. Check engine light never came back on. i did use one off of a Maxima as per a video i saw how to relocate the knock sensor.

Has the feel sensor been placed below the collector for the print, putting on top of something change? or it works in the same way in the advance of the stitch.

I bought an aftermarket knock sensor compatible with the Xterra. If you buy the OEM knock sensor from the the dealer it will cost a whopping $280

@unti419 2 года назад

I'm going to try it this weekend if the parts arrive, seems simple enough. My 3.3 Nissan is stalling at stop signs and this is the only codes I am getting. Anyone know what the symptoms are for a bad knock sensor? I had the same codes an a 350 Chevy that kept going into reduced power. Change the sensor and it didn't fix it.

@NelsonTODDcom 2 года назад

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

@jarrlan Год назад

If anything when you do replace it and the engine light doesn't go away.. there could be other problems. But if not you can just clear the code yourself or a shop can. And in theory if you did it righ, the light will never come back

@diycast6914 Год назад

Luckily, my check engine might automatically turned off, but in some cases you may have to clear it with a scan tool or if you don't have one, you can disconnect the battery, put the key in the on position and press the horn a few times which will discharge any reserve eléctricity/memory stored in the ECU

@Debosway77 2 года назад

How does relocating the sensor pick up any knock if it’s not in the motor and is now sitting on top of the intake manifold?

@diycast6914 2 года назад

This is by far the quickest and most common location for relocating the knock sensor on the VG33E motor. It may not be ideal enough for detecting mild knocking but it will still detect severe knocking. It is also ideal enough to clear a knock sensor code which will set on your Check Engine light and prevent your car from passing smog. The other option is to pay a mechanic $500-$2,000 to replace the knock sensor in the original location which like I said is a very expensive time-consuming repair.

@chadw6448 3 года назад

I can easily do the splice like everybody else but now I'm trying to unplug it like you did and I honestly can't even touch it with my finger I saw it with my probe camera..... You got to be a ninja cuz I can't even get to the end of the wire to even touch the connector.... I'm going to try one more time to see if I can get in there I'd rather just unplug. But I got to be honest I might wind up having to cut my wires.

@diycast6914 3 года назад

Yea it is a tight squeeze and you will cut up your hand a bit..I was barely able to touch the end of the connector, but if u can do just that, then hopefully you can apply enough pressure to break off the connector like I did. If you can't, then try finding a pair of smaller hands 🤷‍♂️

@jskyg68 2 года назад

Just do a nice job splicing, it's not the end of the world. lol A little solder and heat shrink goes a long way.

@christophersherlock8663 2 года назад

FYI - this got rid of my code but smog shop said it’s an automatic fail with this knock sensor relocation. It’s considered an emissions system alteration. ☹️

@diycast6914 2 года назад

You must have gone to a very strict smog station and/or a place where they wanna sell you a repair job to undoing the knock sensor relocation. Most people get away with it because most shops don't consider this a direct modification which will increase harmful emissions. If you continue driving a car with an engine that's knocking bad enough to fail emissions, then no need to worry about it polluting the Earth cause it will die very soon.

@angelr7216 2 года назад

@jaxsully1 Год назад

Why cant you just cut the wire to the sensor, and use a new sub harness to the new location?

This is simply an alternate method to save time/effort and leave the original wire harness/connector intact if you don't wanna deal cutting/splicing/crimping

@alecb8509 Год назад

Doing this "repair" is the same as pulling your check engine light bulb. If fixes the symptom but doesn't fix the problem.

@diycast6914 Год назад

The only time I WOULDN'T recommend this is if you vehicle has a knocking problem...then the new relocation of the knock sensor won't be ideal. As for pulling the bulb 💡 for your check engine light, that is different cause most smog places will detect that and fail you. This relocation however will enable you to pass smog.

@ricdonato4328 8 месяцев назад

When capturing video always hold the camera horizontal. Every TV screen, monitor screen, computer screen, movie theater screen, are orientated horizontally. Your video the camera is vertical, thus the left one-third, and right one-third of the screen is cut off. Your video is a stick video, tall and narrow thus appears. Watching It is similar to looking through a tight keyhole or wearing horse blinders.
