Subaru engine knock can be caused by several factors, including incorrect ignition timing, low-quality fuel, or excessive carbon buildup in the combustion chamber. Additionally, a lean air-fuel mixture or issues with the engine's cooling system can contribute to knocking. Regular maintenance, including fuel quality and timely oil changes, is essential to minimize these issues. If knocking persists, it's advisable to have the engine checked by a professional to prevent potential damage.
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.

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.
