Modern cars are more and more equipped with new technologies, apart from the comfort of use it can bring, technology also has the advantage of saving fuel or reducing the pollution released by our cars. This is exactly the subject matter of our article content of the day, we are going to look at the complications of the lambda sensor on Mercedes Benz E Class , this sensor also known as oxygen sensor plays an essential function. To find out, first, we are going to identify what a lambda probe is utilized for, then, what are the lambda sensor complications on Mercedes Benz E Class and how to fix them.

What is a lambda purpose on Mercedes Benz E Class?

So we begin our content with the interest of a lambda sensor on Mercedes Benz E Class , we will first see what is the function of this probe and then how it functions.

Role of a lambda sensor on Mercedes Benz E Class

First produced by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission standards. Also called oxygen sensor on Mercedes Benz E Class , its task is to regulate the amount of oxygen in the exhaust gases, this will enable the engine unit to change the air/fuel mixture to lower the pollution released by the motor vehicle and reduce the car’s fuel consumption.

Lambda sensor process on Mercedes Benz E Class

Before describing you the different complications of lambda probe on Mercedes Benz E Class , we will look a little more in detail at its functioning to allow you to discover precisely how it functions and thus to consider more serenely the correction of a problem associated with 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 think 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 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 part you are undoubtedly most enthusiastic about this content, how to proceed if you have a lambda sensor issue on Mercedes Benz E Class . In a first step we will find out how to locate a lambda sensor HS and in a second step how to change it.

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

.
It is essential to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this info can vary according to the year of your Mercedes Benz E Class, your driving, and the good performance of your engine unit. A poorly maintained engine unit that produces unburned gases may permanently corrupt your lambda sensor. One of the clues that can notify you of a faulty lambda sensor on Mercedes Benz E Class may be the engine unit light turns on, if you want to turn off the engine light of your Mercedes Benz E Class, do not think twice to seek advice from our dedicated content to see the process to follow. The only effective way to ensure that you have a lambda sensor issue on your Mercedes Benz E 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 E Classhow to read the fault code of a Mercedes Benz E Class. Please be aware that if you have complications with one of your lambda sensors, the only remedy to correct them will be to change the faulty sensor.

How to change a lambda sensor on Mercedes Benz E Class?

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

The replacement of a lambda sensor is quite simple to execute and you will have the ability to do it yourself with a minimal 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 fairly quickly. To replace it, it will be required to put your Mercedes Benz E 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 E Class.
