So I threw a check engine light P0135 and now I need to replace my pre-cat 02 sensor.
I have a 99 Civic w/ a D16Y7.

It's 90 for a new one from local auto store, but I can wait a day and ask/search around tommorow for a used one from an auto dismantler or salvage yard.

So my question is, do I have to get the exact same o2 sensor for my year and engine, or are other 02 4 pin sensor's compatible??? which ones???


thanks
