Hi,
on the way R N Golden (Subaru main dealer) to get some parts, the "check engine" light came on and then went off. Decided to have it put on the diagnostics while I was there and it flagged up oxygen sensor fault.
The part number it required is 22690aa320, main dealer cost £188.44.
A visit to Andrew Pages then. Problem is that they are listing 2 oxygen sensors for my car ,post and pre cat.
After an internet trawl I ordered direct replacement for above part number from here http://www.lambdasensor.com/main/mindex.htm for £66.
Can anyone enlighten me as whether there are two sensors on my car (MY00) and of their location.
Also if there are two, is the above part number the pre or post cat sensor.
Regards Damchief.

 

I have the same model and you have only 1 lambda at the top of the down pipe just next to turbo precat
you can use the bosch universal one and just solder the wires to the plug and costs about £45 all in from dingbro

 

Cheers
