When do I need to replace the oxygen sensor?
If the sensor after the catalytic converter shows minimal changes from the reading on the first oxygen sensor, it is a sign that the catalytic converter is not working properly. Modern vehicles with V-6 or V-8 engines could have as many as four O2 sensors — one located in each cylinder bank and one after each catalytic converter.
What does the O2 sensor on a catalytic converter do?
This O2 sensor monitors the operating efficiency of the catalytic converter. If the sensor after the catalytic converter shows minimal changes from the reading on the first oxygen sensor, it is a sign that the catalytic converter is not working properly.
Where are the O2 sensors on a V-6 engine?
Modern vehicles with V-6 or V-8 engines could have as many as four O2 sensors — one located in each cylinder bank and one after each catalytic converter.

What does the O2 sensor on a car do?
One of the most important sensors in modern cars is the oxygen sensor. Also known as the O2 sensor because O2 is the chemical formula for oxygen, the oxygen sensor monitors how much unburned oxygen is present in the exhaust as exhaust exits the engine. By monitoring oxygen levels, the sensor provides a means of measuring fuel mixture.
Are there any problems with the Mercedes oxygen sensor?
As evident in the information above, the efficient working of the Mercedes Benz oxygen sensor is better for the engine. Mercedes oxygen sensor related problems can lead to decreased performance and snowball into bigger issues with the car.
What should I do if my cat converter goes off?
Might be worth a shot. The other option is an 02 spacer assuming your Cat’s are indeed good and you didn’t get a defective replacement. Basically moves the sensor out just a little and it keeps the code from going off. This was a common fix on the previous body style Oddy’s.
