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.

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!

@@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.

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

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

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 жыл бұрын

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.

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 жыл бұрын

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 🤷‍♂️

@diycast6914 2 жыл бұрын

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.

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.

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

@diycast6914 11 ай бұрын

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.
