What is the function and operation of an oxygen sensor on 2006 Mercedes-Benz C280?

An oxygen sensor is a galvanic battery which produces a voltage in uncombusted oxygen in exhaust. Upstream sensors modulate pulse width of fuel injectors in order to have an optimum combustion whereas downstream sensors gauge the efficiency of catalysts. There must be proper connections, temperatures and unleaded fuel. The process of replacement includes heating the engine, disconnection, unscrewing and installation of the sensor.
