Modern automobiles are more and more pre-loaded 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 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 S Class , this sensor as well known as oxygen sensor plays an important function. To find out, first, we are going to find out what a lambda probe is used for, then, what are the lambda sensor complications on Mercedes Benz S Class and how to solve them.
What is a lambda task on Mercedes Benz S Class?
So we start our article with the benefit of a lambda sensor on Mercedes Benz S Class , we will first see what is the function of this probe and then how it works.
Role of a lambda sensor on Mercedes Benz S Class
First produced 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 S Class , its objective is to control the amount of oxygen in the exhaust gases, this will allow the engine unit to modify the air/fuel mixture to reduce the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.
Lambda sensor process on Mercedes Benz S Class
Before explaining you the different complications of lambda probe on Mercedes Benz S Class , we will look a little more in outline at its functioning to allow you to discover exactly how it works 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 controlling the amount of oxygen present in the exhaust gases . One could naively believe 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 just 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 modify the quantity of air and gasoline injected into the engine unit to improve the combustion .
Lambda sensor issue on Mercedes Benz S Class
At last, we are now going to attack the section you are obviously most interested in this article, how to handle it if you have a lambda sensor issue on Mercedes Benz S Class . In a first step we will see 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 S Class is HS
It is important to know that a lambda sensor has in general a lifetime of 150 000 km , this data can differ according to the year of your Mercedes Benz S Class, your driving, and the good working of your engine unit. A poorly taken care of engine unit that produces unburned gases may forever damaged your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Mercedes Benz S Class might be the engine unit light turns on, if you want to turn off the engine light of your Mercedes Benz S Class, do not hesitate to visit our dedicated article to see the process to stick to. The only effective method to ensure that you have a lambda sensor issue on your Mercedes Benz S Class and to pass your car to the diagnostic case, for that do not hesitate to consult our tutorial which explains you Mercedes Benz S Classhow to read the fault code of a Mercedes Benz S Class. Please be aware that if you have complications with one of your lambda sensors, the just solution to correct them will be to change the faulty sensor.
How to change a lambda sensor on Mercedes Benz S Class?
And at last, we are going to focus on the correction of lambda sensor problems on Mercedes Benz S Class , by detailing 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 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 fairly quickly. To replace it, it will be required to put your Mercedes Benz S 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 S Class.
