I would like to know the exact location of the oxygen sensor on my 300E with 2.6 engine. There are 3 sensors on the left side of engine block on top above injectors.
Is one of these the part I am looking for?

one 02 sensor is located on the exhaust manifold before the catalytic convertor, and one after the convertor.
