I need to replace the knock sensor (ks) in my 2000 Max. Where is it located? Is it a difficult fix? I already have the replacement ks.

 

go to youtube the have how to videos and i think it is similar to a 1995 maxima where the knock sensor is the intake manifold.

 

Thanks, is it going to be difficult?

 

not that difficult but have to have the right tools sivel socket and a little patience

 

Thank you, I also have to do a cylinder 2 ignition coil, do you have any experience with those?

 

my bad found out your car has swirl intake its different than a 1995 have to take the lower intake out. That requires someone with mechanic experience

 

what you could do is try to use better octame fuel might help with the kr code

 

sorry octane fuel

 

So running premium or ultra plus would fix the issue entirely? Or would I have to consistently run the high octane fuel?

 

Also where's the lower intake?

 

it would help because lower octane fuel makes a car knock try using good fuel it hould help.

 

As far as the intake its on top of the motor but the knock sensor is at the bottom and in order to get to it you have to take the intake off, not something for a novice.

 

its not like the 4th gen max its a lot harder to get to.

 

You can take of the intake box and look in there (and spend a lot of time working around the coolant pipe...), but yeah, might as well take off the whole intake LOL

 

Good luck on that, it's a B*TCH to do, and definitely have to remove your upper intake, and some hoses and a lot of bolts. if you are going to undertake this task, you will need to replace the intake manifold gasket because once you take it off, it's not reusable. I would do your home work before doing this job on your own, otherwise, leave it to a professional because it does take quite bit of time to just get one simple knock sensor.
