Modern automobiles are increasingly 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 released by our automobiles. This is exactly the subject matter of our content page of the day, we are going to look at the complications of the lambda sensor on Mercedes Benz GL Class , this sensor as well known as oxygen sensor plays an essential role. To find out, first, we are going to find out what a lambda probe is employed for, then, what are the lambda sensor complications on Mercedes Benz GL Class and how to fix them.
What is a lambda fonction on Mercedes Benz GL Class?
So we start our article with the interest of a lambda sensor on Mercedes Benz GL Class , we will first see what is the job of this probe and then how it functions.
Role of a lambda sensor on Mercedes Benz GL Class
First produced by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission specifications. As well called oxygen sensor on Mercedes Benz GL Class , its objective is to control the amount of oxygen in the exhaust gases, this will allow the engine unit to adapt the air/fuel mixture to lower the pollution released by the car and lower the car’s fuel consumption.
Lambda sensor operation on Mercedes Benz GL Class
Before describing you the different complications of lambda probe on Mercedes Benz GL Class , we will look a little more in detail at its functioning to allow you to understand precisely how it functions and thus to consider more serenely the correction of a problem related to it.
As we told you, a lambda probe has the task of controlling 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 needed 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 interest is to have more exact data by compiling the two probes. These data are sent to the ECU which will modify the quantity of air and gasoline inserted into the engine unit to optimize the combustion .

.
At last, we are now going to attack the section you are absolutely most keen on this article, how to handle it if you have a lambda sensor issue on Mercedes Benz GL 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 GL Class is HS
.
It is essential to know that a lambda sensor has generally a lifetime of 150 000 km , this info can fluctuate according to the year of your Mercedes Benz GL Class, your driving, and the good working of your engine unit. A poorly taken care of engine unit that produces unburned gases may permanently corrupt your lambda sensor. One of the clues that can warn you of a defective lambda sensor on Mercedes Benz GL Class might be the engine unit light turns on, if you want to turn off the engine light of your Mercedes Benz GL Class, do not think twice to visit our dedicated article to see the process to stick to. The only effective method to be sure that you have a lambda sensor issue on your Mercedes Benz GL Class and to complete your car to the diagnostic case, for that do not think twice to seek advice from our guide which explains you Mercedes Benz GL Classhow to read the fault code of a Mercedes Benz GL Class. Please be aware that if you have complications with one of your lambda sensors, the only solution to resolve them will be to replace the defective sensor.
How to replace a lambda sensor on Mercedes Benz GL Class?
And finally, we are going to concentrate on the correction of lambda sensor problems on Mercedes Benz GL Class , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite basic to accomplish and you will have the ability 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 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 quickly. To replace it, it will be necessary to put your Mercedes Benz GL 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 complications with your lambda sensor on Mercedes Benz GL Class.
