I'm getting the famous P0325 code on my 2000 legacy gt... it came right back when I cleared it so it's probably not lying to me with the 325 code... picking up a new sensor today but have no idea where it's located on the engine...

 

so where can I find this bugger? any tricks to replacing it I should know about in advance?

 

thanks!

Last post is correct, 12mm bolt, 10 inch extension makes the job a lot easier.

Note, I did not have to remove the intake pipe on my 96 Legacy GT.
