All right, so you have a Nissan Pathfinder and you have a ton of miles on it and you end up with a nox sensor code The nox sensor is kind of a pain to replace on this vehicle. So I'm gonna show you a hack how to get around it So here's the codes that we have the nox sensor codes So that's what we're gonna try to get rid of see if we can fix this So I've got my Boroscope and I can see the nox sensor right there and And I've got the wire well the Boroscope going down behind the intake and underneath So now just trying to follow the wires Just see where the wires go So I traced the wire back and it happens to be this wire Right here, so if you look for You see this fuel injector You see that fuel injector right next to that fuel injector that's on the backside on the passenger side Right above the head So this wire that goes down So I'm gonna try to open up some of this insulation and just make sure the wire colors are the right wire I Got most of that insulation off the wire and that's exactly what I was looking for a white wire Which is good and it looks like it's a white wire with the ground wire surrounding it so there's like underneath the original insulation Was the black wire and when I took off some of that insulation there's the ground is encased Around the white wire which I hate when they do that stuff You just mix it harder, but I can make my own ground if I have to but either way That's the wire I'm gonna tap into the white wire right there Here's the part that I ordered here's a knock sensor and I ordered a wiring harness now something that's weird about this wiring harness If you look at it the harness that connects to the knock sensor only has one terminal only one wire coming out So does that mean the knock sensor grounds itself? So that's kind of interesting Not really sure about that but If you look at the other end we're connects we're supposed to connect into the vehicle which this isn't the exact Knock sensor for this vehicle But I'm gonna try it If you If you look at that end that has two wires so either way I'm gonna cut this wiring harness up Because we're gonna cut the wire here and splice it into the vehicle harness and Then plug this in and relocate this well, let's try it out Yeah, that's weird it just goes to nowhere To get the wires together I'm actually gonna use a heat shrink butt connector on these work really good and It should keep out of keep out the corrosion over time sometimes these do Go bad and you have to replace them but for the most part they work really good The disadvantage of soldering it is if you put too much solder on here if the Contacts not gonna be that good So if you were gonna do that using a metal crimp of some sort might be more More helpful, but for this I'm just gonna use this You Sentai here's the wire I'm gonna try to cut it as low as possible to give myself a little slack It's easier So here's our wire Separate that insulation wire from the white wire Just gonna trim that off because I don't need that You said it's warm up today All right, let's place this in Man crimp All right nice and tight. That's good Left my torch at work Left my torch at work make sure you don't have any fuel leaks when you do this Whoops All right before I tape this all up I Am we'll test it and make sure everything works good But I could just put that like that and just tape up this end So I'm gonna root this I'm gonna try to put this On this bolts right here plug it in right there Probably need a longer bolt yeah, that's too short So I'm gonna have to get a longer bolt I'm gonna clean this up. I could do Take this bracket move it down With the bracket down here No, let's see how it looks and see how it works first Just take that bracket off for now So So here's the knock sensor I'm gonna stick it right there. I had to get a longer bolt Be very careful with these knock sensors. They are sensitive. You don't want to drop them and It's extremely important to torque them properly. So get this bolt started I'm gonna torque this to 15 foot pounds It's pretty good Plug it in See how this is gonna go I don't know if I can make it to be there All right, that's cool No No codes So that's pretty cool All right, so so far it seems to be working But so that seems to work overall do I think this is a good idea? No, this is a horrible idea You shouldn't hack up your cars definitely don't do this to a customer's car if you want to do it to your own car that has over 200K on it It might be worth the risk either way. I'm kind of excited that it worked Over the week, I'm gonna check and make sure I don't have any other knock sensor codes If you like this video check out some of my other videos. I do a lot of automotive and mechanical type stuff. Thanks Oh Hey, I didn't see you there checking it a week later still running great and still no codes no check-in lighter nothing so good luck out there
