that the knock sensor does
the knock sensor in on the drivers side of the block toward the rear, and it's under the intake manifold.
on top of the engine under the air box
It is located on the engine block drivers side.
Its on top of the engine by the fuel injection (remove the air intake first). Need a 10mm socket with a long extention.
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 depends entirely on what happened to it to make it need repairing.
On a 1999 Subaru Legacy Outback, the knock sensor is typically located on the engine block, near the intake manifold. It is usually found on the driver's side, towards the back of the engine, and can be accessed by removing some components for better visibility. The sensor is a small, cylindrical device screwed into the engine, designed to detect engine vibrations and adjust timing accordingly.
If somebody knocks on the front door of the Subaru, the KNOCK sensor, sets off the KNOCK Alarm....LOL
on top of the engine block under the intake manifold. it can be accessed without removing the manifold. easy fix!
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.
When is sends a code to the ECM that it is malfunctioning. Usually a PO 325 but the codes are slightly different depending on the model and year. You can get a complete Subaru PO listing if you Google it. If there is no code, your knock sensor is fine.
