Find the one with the 98 pound weakling wielding the wrench. The knock
sensor is under the intake manifold. You can see it but the space is really
tight. you might be able to reach in and touch it if you have really thin
hands. This is why the prescribed procedure includes removing the intake
manifold. When I changed the KS on my '96, my wife (98 pounds) was able to
reach in and thread the bolt into it. Others have had some success with
wrenches with long extensions and u-joints.
Just out of curiosity, why do you want to change it? A good KS will
occasionally throw a code anyway (probably why it doesn't light the
check-engine light). Reset the codes and drive it for a while & see if the
code comes back before you do anything to it.
You should go ahead with the O2 sensor though. That's a real fault and
probably what lit your engine light.
