Where is the bank 2 sensor 1 located on a KIA optima 2005?

On a 2005 Kia Optima, the bank 2 sensor 1 oxygen sensor is located on the exhaust system, specifically on the exhaust manifold or just after it. Bank 2 refers to the side of the engine opposite to bank 1, which is typically where cylinder 1 is located. For the 4-cylinder engine, this means bank 2 is on the opposite side of the engine, while for the V6, it will be on the side that does not contain the first cylinder.
