Hi all, I'm replacing a replacement knock sensor that was cut into the wiring harness on my 1999 Outback wagon. A mechanic friend has a sensor part #22060aa070 that is for 2000-2001 Outbacks. I need part #22060aa061 for my 99 according to the dealer. My question is since I have to cut out the connector anyway, not using the harness plug in connector, can I use the one I can get for a lot less or is there also a difference in the sensor itself? By the way, I've already cleaned, reposistioned etc. the old one to no avail. Thanks again, Bob

One way to find out.

 

The knock sesnor is just a piezoelectric sensor, like a microphone. It makes an AC signal and the ECU processes that signal.

 

If it was me I would give it a shot.
