Hi, I am in need of new oxygen sensors and am unsure what I am looking for when purchasing. I've been informed I am in need of Oxygen sensor 2 Bank 2. However, when searching, there is ony upstream front/downstream front OR upstream rear/downstream rear. To my understanding, Bank 2 is rear, but is sensor 2 upstream or downstream?
