Do you need a new Mercedes C220 Oxygen Sensor? There are a few symptoms that can let you know your O2 sensor has already failed. If your engine light comes on and nothing else is obviously wrong, the oxygen sensor is a likely culprit. If you find your engine surging and/or hesitating, a failed oxygen sensor may be at fault.

If you suddenly find yourself using a lot more gas, a failed oxygen sensor is one of many possible explanations. If your engine is producing unacceptable emissions and you fail an emissions test, your O2 sensor is one of the first things to check.

Finally, if your catalytic converter goes out much earlier than it should, that means you probably should have changed your oxygen sensor quite a while ago. To get the most out of your engine, you should replace your oxygen sensor at least every 60,000 miles. A car that is driven only four hours a day processes millions of liters of exhaust every week. Your O2 sensor constantly tests all of that exhaust to try to make sure your engine uses exactly 14.7 times as much air as it does gasoline. This is the perfect ratio of air to gas to enable your engine to run at peak efficiency. The O2 sensor uses a small electric charge and a voltage detector to determine what proportion of air to gas is in your exhaust. It sends this information to your car’s computer, which automatically adjusts your fuel injection settings to try to maintain the perfect proportion of 14.7 to 1.
