Knock Sensor replacement Nissan Xterra
Complete knock sensor repair from start to finish.
Knock Sensor: amzn.to/2IFFiof and extension to relocate: amzn.to/2Lli1pf Less than 20$ on Amazon
The car has a hard fault code P0325 Knock Sensor Circuit Malfunction. After diagnostic was performed it was determined that the knock sensor would have to be replaced.
Unforchanetly on this Nissan Xterra, the knock sensor is not acceptable unless the upper and lower intake manifolds are removed. Labor time to do this by the book is about 5 hrs. So not the easiest or the cheapest repair.
There is an option to relocate the knock sensor to save money. I will tell you in my video the pros and cons of trying to relocate the knock sensor.
The purpose of the knock sensor is to retard the timing to prevent cylinder detonation, in turn, preventing engine damage. The knock sensor works by sensing engine vibrations caused by cylinder detonation.

Good job. your saving money and learning many things that will help in the future. you will make mistakes, break connector clips, move your harness around till it looks like the picture you took at the beginning. When you are done you will say" well that wasn't that hard". I did it and now I think I can do it in an hour, because of what I learned. I would like to mention that I took a vacuum on the engine first to see if it was worth the sensor repair, and I had a steady 20 inches and went on with the job. Go for it. Let us know how it feels when you crank it up.

Careful of the wire connectors as they are brittle. Take before pictures to help remember where everything goes.

It needs to be on the engine block to work correctly. You can not move it to the intake and still have it do its job. The engine light will stay out but it will not be doing anything. That's just a workaround for people that don't have the means of pully the intake off.

That was there is nothing else to dismantle from the upper intake. I can remove my upper intake in about 15 minutes. Also, if you plan on working on your engine often, I recommend the coolant bypass. This makes it a 10 minute job.
