The knock sensor is a piezo element that detects vibrations and creates fluctuations in the signal voltage. These vibrations are present throughout the engine and the piezo can detect these vibrations from any point that is connected to the head / block. The bolt running through the manifold provides an adequate connection to transmit the vibrations to the sensor. Even in the factory location, the sensor is able to pick up vibrations from the cylinders located on the front of the engine. Because those vibrations travel throughout the engine block and head. Short answer: YES the sensor functions in the new location.

Yes, many older Xterra vehicles have this relocation performed. It is an acceptable repair and stops the knock sensor trouble codes.

That’s my wife. Our eggs. Our jar.

Also your egg farts 😎🎭✌️

I will refund your price of admission to see this video.

I only know to pull it from the harness at that end.

😂😂😂 when you try to criticize someone only to show your own ignorance.

Nope, I'm not criticizing in the least. And yes, I am ignorant. That's why I'm asking. @@thesaltysquirrel3425

The only purpose of the plug is to prevent you from servicing the idle jet. This has historically been a serviceable item. I will not speculate why a tamper - proofing plug was placed there, I will only say that as evidenced here by the successful users, that this jet is serviceable and removing the tamper plug to access it does zero harm to the carburetor. I would add that a retired, 30 year Coast Guard Maintenance Chief taught me this.

Awesome! Thank you very much! I'll give it a shot. And I'm ashamed to admit it, but I currently work for the Coast Guard. (Canadian)@@Mrportajon

The knock sensor is a piezo element that reacts to particular frequency of vibration that is carried through the engine. Relocating the sensor has been effective for scores of these vehicles to clear the trouble condition and keep high mileage vehicles operating for owners that don’t wish to invest the money or time in a vehicle that is otherwise only worth perhaps $1,500. My Xterra has been over 50,000 miles since this relocation with no trouble codes or ill effects. The repair has proven effective both mechanically and economically.

my xterra was 1100 and it has no reverse. i WANT it to blow up

Hey there.... not sure what is going on there. First, I would double check everything. Check the resistance between the chasis and the positive terminal on the sensor. Make sure it within the range noted in the video. If the sensor is out of range, it's either a bad sensor or the wrong sensor. THe next thing that could be going on is that the coaxial wire going back to the ECM could be dmaaged, shorted, etc.... it is possible that your knock sensor was not bad at all. If the wire is broken, shorted or grounded somewhere between the the ends.... that is a problem. I have never checked to see what the ohms shouls be reading back the other way.... but I would disconnect the wire, then check resistance between the center conductor and the braided shield, then between the center conductor and the chasis. it should be the same and it sshould not be a dead short.... wish I could tell you what it should read, but best I can say is that the two readings should match and it should not be a dead short.

1999 Maxiam is what I used.

That is the throttle / high jet. The whole carb and clean it. The best thing is an ultrasonic cleaner. It's a liquid bath with low frequency sonic vibrations. It will clean the whole carb thoroughly. You can get one at harbor freight, or you can do like I did and swipe your wife's jewelry cleaner.... it's the same unit. Carb comes off easily and easily reinstalled.

That should say "remove the whole carb and clean it".

Thanks Jon.....Is the "high jet" also set at 2 1/2 turns from snug?

@@kerrywages9631 The general rule for carbs is to start at 1 1/2 turns and adjust from there.

Hey there, I do not know of anything special about the Maxima KS except that it comes with a wiring harness. Could the piezo element be more sensitive and therefore works better from the new position ? Maybe.... if that is the reason, I haven't heard anyone state that. Just a thought I had. That would be the only difference I can think of. Use your ohm meter to check the shield drain wire jacket to the chasis. If the shielkd conductors show a dead short to ground, then the shield is already grounded on the other end. You can just cut them off. If the shield is NOT shorted to the chasis, then you can either attach it to the engine with a lug OR.... remember that one of the terminals in the knock sensor is attached directly to the base of the sensor and IS a ground. Just use the correct connector and make sure the shield goes to the ground terminal and the center conductor goes to the one that measures 570 ohms. Hope that helps.

@Mrportajon Yes, this does help. Thank you for answering my questions! I just wanted to make sure I had all the information I needed before attempting to relocate the knock sensor.

Good find. With motors designed to be portable, the fuel caps will always some sort of mechanism to allow for the cap to be liquid tight during transport. Always a good idea to check that the tank can breath.

Never seen that. If the cable is "co axiial" that specifically means a single, center conductor. Two conductor wires can be shielded, but that is not coaxial cable. Not sure what you have found on your Xterra.

That's great ! Glad you got your motor running right. Ours was on the dinghy, so I kept the 10mm socket and a little screw driver in the tackle box and a can of carb cleaner under the seat.

Hi there. Yes, the Xterra has operated perfectly without any trouble codes since this video was made. It's a great old SUV.

Hey there, just seeing this. It could be frozen or there could be a set screw in the swivel joint. Outboards often can be set in one direction with a "set screw" on the collar for boats that are steered with a separate rudder. Check closely on the collar where the shaft passes through and see if there is a set screw or bolt. Then check for a grease fitting on the collar. Loosen the set screw and / or grease the collar and see if it will turn. Unfortunately I sold this motor a while back so i don't have one to look at.

@Jon Durham I was able to get it broke free, just shot some penatrating oil in the grease fitting and then torched it lol

Yes

Hope you got it figured out.

Mine does well if you back it out 2 1/2 turns from being snuggly seated.

@@Mrportajonthat’s correct, manual says 2 3/4 +- 1/2 turn
