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.
can anyone help me please Its the sensor directly under the intercooler remove the intercooler and a couple of airpipes and you will get at it easiar.
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.
Where is the knock sensor located on a 1999 Subaru Forester?
that the knock sensor does
If somebody knocks on the front door of the Subaru, the KNOCK sensor, sets off the KNOCK Alarm....LOL
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 the knock sensor isn't working, the computer won't be able to tell that anything is wrong. Run a diagnostic code anyway. Sometimes it won't turn on a light if it's just a knock sensor.
its under the air intake. its hard to miss. you dont have to take the intake off to see it either. And i believe its a 10mm bolt, simple. Go to http://www.lovehorsepower.com/SubaruDocs/subaru_legacy_knock_sensor.htm there you will find photos on how to remove and reinstall the knock sensor
Under the intake manifold.
Knock sensor/vibration sensor
the knock sensor in on the drivers side of the block toward the rear, and it's under the intake manifold.
