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.
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.
Knock sensor/vibration sensor
Not necessarily.
on top of the engine under the air box
It is located on the engine block drivers side.
Where is the knock sensor located on a 1999 Subaru Forester?
You can find the knock sensor on the top side of the engine under the intake manifold. It is easiest to find from the driver's side and is at the back of the engine block.
Under the intake arch on the left side of the engine.
If somebody knocks on the front door of the Subaru, the KNOCK sensor, sets off the KNOCK Alarm....LOL
Knock sensors on the Subaru 2.5 four are located on top side of the engine tucked under the intake manifold on left side near the back of the engine. Looks like a small black donut with a capscrew through the center and wires attached.
Might be your conrods and/or bearings...serious business so let your subie specialist listen and diagnose.
