Latest automobiles are more and more pre-loaded with new technologies, apart from the comfort of use it can bring, technology as well has the advantage of saving fuel or reducing the pollution emitted by our automobiles. This is precisely the subject matter of our content page of the day, we are going to look at the problems of the lambda sensor on Mercedes Benz M Class , this sensor as well known as oxygen sensor plays an essential function. To find out, first, we are going to find out what a lambda probe is utilized for, then, what are the lambda sensor problems on Mercedes Benz M Class and how to resolve them.
What is a lambda purpose on Mercedes Benz M Class?
So we start our article with the interest of a lambda sensor on Mercedes Benz M Class , we will first discover what is the job of this probe and then how it works.
Role of a lambda sensor on Mercedes Benz M Class
First developed by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission standards. As well called oxygen sensor on Mercedes Benz M Class , its objective is to control the amount of oxygen in the exhaust gases, this will allow the engine to modify the air/fuel mixture to reduce the pollution emitted by the car and reduce the car’s fuel consumption.
Lambda sensor process on Mercedes Benz M Class
Before describing you the different problems of lambda probe on Mercedes Benz M Class , we will look a little more in detail at its operation to allow you to figure out exactly how it works and thus to consider more serenely the correction of a problem associated with it.
As we explained to you, a lambda probe has the task of managing the amount of oxygen present in the exhaust gases . One could naively believe that this data is determined upstream of the combustion but it is on the contrary measured at the engine outlet . With the EURO 1 standard there was only one lambda sensor required before the catalyst, but with the arrival of more drastic standards there are now 2 lambda sensors, one before and one after the catalyst . The interest is to have more exact data by compiling the two probes. These data are sent to the ECU which will adjust the quantity of air and gasoline inserted into the engine to optimize the combustion .

.
Finally, we are now going to attack the part you are undoubtedly most enthusiastic about this article, what to do if you have a lambda sensor issue on Mercedes Benz M Class . In a first step we will discover how to find a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Mercedes Benz M Class is HS
.
It is essential to know that a lambda sensor has generally a lifetime of 150 000 km , this statistics can differ according to the year of your Mercedes Benz M Class, your driving, and the good working of your engine. A poorly maintained engine that emits unburned gases may permanently alter your lambda sensor. One of the clues that can alert you of a defective lambda sensor on Mercedes Benz M Class may be the engine light turns on, if you want to turn off the engine light of your Mercedes Benz M Class, do not hesitate to visit our dedicated article to discover the procedure to stick to. The only effective way to ensure that you have a lambda sensor issue on your Mercedes Benz M Class and to pass your car to the diagnostic case, for that do not hesitate to seek advice from our guide which explains you Mercedes Benz M Classhow to read the fault code of a Mercedes Benz M Class. Please note that if you have problems with one of your lambda sensors, the only remedy to solve them will be to replace the defective sensor.
How to replace a lambda sensor on Mercedes Benz M Class?
And at last, we are going to concentrate on the correction of lambda sensor problems on Mercedes Benz M Class , by describing how to replace a lambda sensor.
The replacement of a lambda sensor is quite simple to carry out and you will be able to do it yourself with a minimum of tools and mechanical expertise. A lambda sensor is worth between 25 and 50€ , it is better to replace the 2 lambda sensors present upstream and downstream of your catalytic converter because if one of them is defective the second one risks to drop you fairly quickly. To replace it, it will be required to put your Mercedes Benz M Class on candles and at the level of your catalyst unscrew your probes, disconnect them, reconnect them and screw the new ones . Once re-connected, you should not have any more problems with your lambda sensor on Mercedes Benz M Class.
