Whether you have the 2.2 or the 2.5 engine, it is a very easy job requiring a medium extension and 12mm socket and ratchet. It will take about 10 minutes assuming you are handy with tools.
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.
It is located on the engine block drivers side.
It is threaded into the block, under the intake manifold.
Where is the knock sensor located on a 1999 Subaru Forester?
that the knock sensor does
That depends entirely on what happened to it to make it need repairing.
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.
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.
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.
It only involves one bolt and one wire, but its pretty difficult to access as it lives under the throttlebody.
Looking at the top of the motor remove the air intake and it is below the butterfly on the drivers side top end of the motor.
