It is underneath the intake manifold. If you look straight down from your throttle body, you will see a sensor with one wire coming out and a bolt going through the middle of it, that is the knock sensor.

In a 1998 Subaru Legacy, the knock sensor is located on the top of the engine block and to the left of the engine. More specifically, it is under the left rear intake manifold runner.
Where is the knock sensor located on a 1999 Subaru Forester?
The knock sensor is located near the idle air control solenoid valve on a 2001 Subaru Forester. The knock sensor is responsible for sensing vibrations caused by engine knock.
It is threaded into the block, under the intake manifold.
that the knock sensor does
If somebody knocks on the front door of the Subaru, the KNOCK sensor, sets off the KNOCK Alarm....LOL
That depends entirely on what happened to it to make it need repairing.
on top of the engine under the air box
Remove the intercooler first. The knock sensor is located under its loation. But you will have to remove some breather pipes to get to it. You will need a long ratchet.
It only involves one bolt and one wire, but its pretty difficult to access as it lives under the throttlebody.
I believe the knock sensor is housed at the top of the oil pump. It should be visibly located under the alternator. It's wire should share the same main cable routing as the oil pressure sending unit which is just above the knock sensor and under the left side of the alternator when standing in front of the car. Nothing posotive here, don't quote me
