Looking under the hood, the front bank is bank 2. Bank 1 is where the number one cylinder is located and that is in the rear bank. Sensor 2 is usually after the cat. I'm having trouble with my database at the moment, can't look up anything. I have a set of specification guide manuals, it has your engine, so I knew where the number one cylinder was located, which bank.
