Where is the knock sensor for my 96 isuzu rodeo v6

YAEEH (yet another easter egg hunt)
why do you ask. scan it and it has DTC for knock? nah, bet not.
be best to scan it, no?

usa RODEO.
GM V6 engine with their own 3.2-liter 24-valve SOHC V6
LG6 , i think ended in 1992.
3.2 L 6VD1/6VD1W V6 (bingo)?

ill toss coin, land on 6vd1

some dont have a knock sensor. the 2.6L does.
the 1998 6vd1 has one, but not 96, in usa.

I even looked at your ECU/CPM schematic,
for the V6, and it shows, no knock sensor,(usa spec car)
The EFI spark system used on your car dictates this.
as knock (KS) controls spark timing, (retards it at knock)
but some versions have no KS sensor.

if fitted its on the block top.
has 1 wire. and screws in on a simple stud .
some are under intake manifold
its just a threaded shallow hole in block,
its only a microphone device.
here is the block a real photo.
some have it , others, dont
and one more fact, it came 92 and went and came.98

clear? see red circle below?

Where is the knock sensor located?

knock sensor is located on the back of the engine (toward the firewall). It will probably have a single white wire coming from it and going into a harness under the engine. this concerns the 6 cyl 2.8 liter engine.
