Modern vehicles are more and more equipped with new technologies, apart from the comfort of use it can provide, technology as well has the advantage of saving fuel or reducing the pollution emitted by our vehicles. This is exactly the subject of our article of the day, we are going to look at the problems of the lambda sensor on Mercedes Benz GLK , this sensor as well known as oxygen sensor plays an necessary purpose. To find out, first, we are going to identify what a lambda probe is utilized for, then, what are the lambda sensor problems on Mercedes Benz GLK and how to solve them.

What is a lambda role on Mercedes Benz GLK?

So we begin our content with the benefit of a lambda sensor on Mercedes Benz GLK , we will first discover what is the role of this probe and then how it functions.

Role of a lambda sensor on Mercedes Benz GLK

First designed by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission specifications. Also called oxygen sensor on Mercedes Benz GLK , its mission is to regulate the amount of oxygen in the exhaust gases, this will enable the engine to change the air/fuel mixture to lower the pollution emitted by the car and lower the car’s fuel consumption.

Lambda sensor process on Mercedes Benz GLK

Before describing you the different problems of lambda probe on Mercedes Benz GLK , we will look a little more in outline at its working to allow you to understand precisely how it functions and thus to consider more serenely the correction of a problem associated with it.
As we informed you, a lambda probe has the task of managing the amount of oxygen present in the exhaust gases . One could naively presume that this data is calculated 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 specifications there are now 2 lambda sensors, one before and one after the catalyst . The benefit is to have more precise data by compiling the two probes. These data are sent to the ECU which will adjust the quantity of air and gasoline injected into the engine to optimize the combustion .

.
At last, we are now going to attack the section you are undoubtedly most enthusiastic about this content, how to handle it if you have a lambda sensor problem on Mercedes Benz GLK . In a first step we will find out how to identify a lambda sensor HS and in a second step how to change it.

How to know if a lambda sensor on Mercedes Benz GLK is HS

.
It is necessary to know that a lambda sensor has generally a lifetime of 150 000 km , this statistics can fluctuate according to the year of your Mercedes Benz GLK, your driving, and the good working of your engine. A poorly maintained engine that produces unburned gases may forever damaged your lambda sensor. One of the clues that can notify you of a faulty lambda sensor on Mercedes Benz GLK might be the engine light turns on, if you want to turn off the engine light of your Mercedes Benz GLK, do not hesitate to visit our dedicated content to discover the process to follow. The only effective way to ensure that you have a lambda sensor problem on your Mercedes Benz GLK and to complete your car to the diagnostic case, for that do not hesitate to seek advice from our tutorial which explains you Mercedes Benz GLKhow to read the fault code of a Mercedes Benz GLK. Please note that if you have problems with one of your lambda sensors, the only remedy to resolve them will be to change the faulty sensor.

How to change a lambda sensor on Mercedes Benz GLK?

And at last, we are going to focus on the correction of lambda sensor problems on Mercedes Benz GLK , by detailing how to replace a lambda sensor.

The replacement of a lambda sensor is quite simple to accomplish and you will be able to do it yourself with a lowest of tools and mechanical know-how. A lambda sensor is worth between 25 and 50€ , it is better to change the 2 lambda sensors present upstream and downstream of your catalytic converter because if one of them is faulty the second one risks to drop you quickly. To replace it, it will be required to put your Mercedes Benz GLK 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 GLK.
