EJ25 Subaru Knock Sensor

[NAC]

I have a bad knock sensor code and want to replace the knock sensor.
The problem I have is trying to find this sensor. I've searched this
group and other sources and have not found something that will help me
locate this sensor. Can someone help me find it.

The car is a 1999 Outback with an EJ25 engine.

Thanks,

NAC

Hi NAC!

Can someone help me find it.

Look for a black cylindrical thingie bolted to the engine block more
or less centered, below and behind (damned near underneath) the intake
manifold. Some have a wire with a plug, some have the plug right on
the sensor.
You'll probably have to move a fair bit of intake plumbing and
assorted wiring to get to it, but once exposed, a 12mm (IIRC) socket
on a medium extension will suffice to extract the beast.

ByeBye! S.
