Generally when a code for the knock sensor shows up, you should replace
the sensor. Get it from Subaru, not aftermarket. It's not very expensive.

The knock sensor looks like a 1" dia. steel "O" with an electrical connector
on one side. A 10mm-head bolt goes thru the center of the "O" and attaches
it to the block.

If your 99 impreza is similar to my 95, then the knock sensor is located
on the driver's side of the engine, if you look down between the arms of
the intake manifold on the back end. Use a flashlight and you'll see a round
thing with a bolt going down thru it and a wire coming off the back side.
The bolt will be tight, but shouldn't require more than 20-25 ft-lbs torque
to remove. If it seems stuck, get someone with an impact wrench to
loosen it, don't break off the bolt head, and use a 6-point socket with an
extension to get at it. Disconnect the wire after removing it.

I found a little more info on some other sites. Going to try and pic
up the part today and replace it tomorrow, hopefully that will fix the
P0325, and then we can work on the P0446!!
