Don't worry about the knock sensor code until you get the other problem
fixed. It could have been set by the misfire. After everything is fixed
and reset, then read the codes again to see if the knock sensor returns
(it
will not set the engine light if it is the only code). Only then do you
want to waste the time & effort to replace it.
The knock sensor is located under the intake manifold approximately dead
center on top of the engine. If you have access to somebody with really
tiny hands who can reach up in there, then it can be replaced easily.
Otherwise, its a real pain.
Bottom line - whatever your problem is, the knock sensor did not cause it.
