Want this question answered?
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.
If somebody knocks on the front door of the Subaru, the KNOCK sensor, sets off the KNOCK Alarm....LOL
Knock sensor/vibration sensor
Yes.
Not necessarily.
Could be a bad knock sensor. The ECM may be retarding the timing based on bad input from a faulty knock sensor.
that the knock sensor does
It is located on the engine block drivers side.
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.
The knock sensor is just behind the intake manifold on the top of the engine. It is a few inches below the manifold and all you will see is a bolt with what looks like a very thick washer on it with wires coming out of it. The knock sensor appearance has been described as a small donut. Easiest to see while leaning over the left front fender using a flashlight.
on top of the engine under the air box
