Hi, just joined. I have a 97 legacy outback limited. Just replaced the O2 sensor and the Knock sensor per codes that came up on the diagnostic check. Check engine light stayed off for about 2-3 weeks and came back on a couple of days ago. Ran another code check and the only one that came up was P0141 which I just fixed. Wondering if it could be the new one or maybe one of the other O2 sensors? Any thoughts would be appreciated.

It was a direct replacement. I didn't want to start cut or splicing anything if I didn't have to.

The code scanner is telling me bank 1 sensor 2. I replaced the one about halfway down the car in the middle which I believe is sensor 2 (not sure).

if it is behind the trans, it is the second sensor. 95 - 99, there is only one bank and and basically there is a sensor in / on each cat.

It is. Is it likely at all that the one I put in is defective or stopped working that fast?

The only other suggestion I've had so far is the catalytic converter could be the problem.

Wires and the connector look fine. Outback Limited 2.5, 193047 miles on it. Do you know of a way to test the 02 sensor or the catalytic converter? I don't want to start replacing things unless I know that it is the problem.
