Nothing to really explain

It's down by the oil filter. Easier to reach by removing the intake manifold but can also be reached from underneath.

You can also bypass it by installing a 1 mega ohm resistor.

The knock sensor is interchangeable with a bunch of Nissan models between 91-2002. There's very few model specific sensors. Grab the Hitachi KNS0001 sensor and you'll be good to go. I like rock auto, but you can search your favorite online vendor for it.

Much easier to just remove in the intake manifold. If you have bendy arms, you might be able to get to it from the bottom.

i wound up using a s14 one,when ii removed the old sensor it had a nice crak in it and also the code came around the time i washed engine bay so looks like moisture got in,no more codes with new sensor now.

also this turned into replacing every coolant hose while manifold was off and recommend anyone who does this job to replace those old coolant hoses while you have manifold off.ebay sells a complete hose kit for like $40 if you dont want to run back and forth to auto store.

once you replace all these random coolant hoses which theres like 7 of them, pressure test your coolant system to around 1 bar or whatever the rad cap says BEFORE you bolt everything back up trust me you want to find and fix all leaks while you can still get to the hoses and clamps.

and clean the iacv as it will have carbon buildup and replace its gasket and use a new intake manifold gasket dont cheap out and reuse these gaskets unless you want to risk taking everything apart again over a little boost leak..
