Modern automobiles are more and more furnished 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 released by our automobiles. 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 GLS Class , this sensor as well called oxygen sensor plays an necessary function. To find out, first, we are going to identify what a lambda probe is employed for, then, what are the lambda sensor problems on Mercedes Benz GLS Class and how to solve them.
What is a lambda fonction on Mercedes Benz GLS Class?
So we start our article with the benefit of a lambda sensor on Mercedes Benz GLS Class , we will first see what is the task of this probe and then how it functions.
Role of a lambda sensor on Mercedes Benz GLS 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. Also called oxygen sensor on Mercedes Benz GLS Class , its goal is to regulate the amount of oxygen in the exhaust gases, this will enable the engine to modify the air/fuel mixture to reduce the pollution released by the car and lower the car’s fuel consumption.
Lambda sensor procedure on Mercedes Benz GLS Class
Before explaining you the different problems of lambda probe on Mercedes Benz GLS Class , we will look a little more in detail at its working to allow you to understand exactly how it functions and thus to consider more serenely the correction of a problem related to it.
As we explained to you, a lambda probe has the task of controlling the amount of oxygen present in the exhaust gases . One could naively think that this data is measured upstream of the combustion but it is on the contrary measured at the engine outlet . With the EURO 1 standard there was just one lambda sensor needed 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 benefit 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 injected into the engine to improve the combustion .

.
Finally, we are now going to attack the section you are obviously most keen on this article, how to proceed if you have a lambda sensor issue on Mercedes Benz GLS Class . In a first step we will see how to find a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Mercedes Benz GLS Class is HS
.
It is necessary to know that a lambda sensor has generally a lifetime of 150 000 km , this data can fluctuate according to the year of your Mercedes Benz GLS Class, your driving, and the good performance of your engine. A poorly maintained engine that emits unburned gases may permanently corrupt your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Mercedes Benz GLS Class might be the engine light comes on, if you want to turn off the engine light of your Mercedes Benz GLS Class, do not think twice to visit our dedicated article to see the procedure to stick to. The only effective method to be sure that you have a lambda sensor issue on your Mercedes Benz GLS Class and to complete your car to the diagnostic case, for that do not think twice to consult our tutorial which explains you Mercedes Benz GLS Classhow to read the fault code of a Mercedes Benz GLS Class. Take note that if you have problems with one of your lambda sensors, the just remedy to resolve them will be to change the faulty sensor.
How to change a lambda sensor on Mercedes Benz GLS Class?
And finally, we are going to concentrate on the correction of lambda sensor problems on Mercedes Benz GLS Class , by detailing how to replace a lambda sensor.
The replacement of a lambda sensor is quite basic to carry out and you will be able to do it yourself with a minimal of tools and mechanical expertise. 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 necessary to put your Mercedes Benz GLS 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 GLS Class.
