Do you need to replace your Mercedes C280 Oxygen Sensor? Your oxygen sensor is a small part that does an important job and which can take a lot of abuse there inside your exhaust. Even if you only use your C280 a few hours a day, your engine produces thousands of liters of exhaust each minute you drive at normal highway speeds. So your oxygen sensor has to deal with millions of liters of exhaust every week! The oxygen sensor sends a tiny electric charge through your exhaust and uses a voltage meter to determine the proportion of gasoline and air used by your engine.

In order for your engine to work most efficiently, it should use exactly 14.7 times as much air as it does gas. The O2 sensor constantly monitors the air to gasoline ratio and sends that information to your computer.

Based on the sensor’s readings the computer adjusts the fuel injection settings to try to maintain the optimum 14.7 to 1 ratio of air to gas. When it’s working properly, this not only lets your engine perform at peak efficiency, it also helps your fuel burn more cleanly. The oxygen sensor makes sure there is enough oxygen in your exhaust for your catalytic converter to work properly. If your O2 sensor goes out and you don’t replace it quickly, your catalytic converter may fail prematurely. Without a working oxygen sensor your engine will produce unacceptable emissions and will not pass state emissions tests. Other signs of a malfunctioning O2 sensor include otherwise unexplained surging and hesitation from your engine, or a sudden drop in fuel economy.
