Latest cars are more and more pre-loaded 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 content page of the day, we are going to look at the problems of the lambda sensor on BMW X6 , this sensor also named oxygen sensor plays an necessary purpose. To find out, first, we are going to find out what a lambda probe is utilized for, then, what are the lambda sensor problems on BMW X6 and how to fix them.

What is a lambda fonction on BMW X6?

So we begin our article with the interest of a lambda sensor on BMW X6 , we will first see what is the function of this probe and then how it works.

Role of a lambda sensor on BMW X6

First created by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission requirements. As well called oxygen sensor on BMW X6 , its goal is to regulate the amount of oxygen in the exhaust gases, this will allow the engine unit to adapt the air/fuel mixture to decrease the pollution released by the motor vehicle and lower the car’s fuel consumption.

Lambda sensor operation on BMW X6

Before explaining you the different problems of lambda probe on BMW X6 , we will look a little more in outline at its functioning to allow you to understand precisely 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 job of managing the amount of oxygen present in the exhaust gases . One could naively think 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 requirements there are now 2 lambda sensors, one before and one after the catalyst . The interest 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 problem on BMW X6

.
At last, we are now going to attack the part you are certainly most enthusiastic about this article, what to do if you have a lambda sensor problem on BMW X6 . In a first step we will find out how to find a lambda sensor HS and in a second step how to change it.

How to know if a lambda sensor on BMW X6 is HS

.
It is necessary to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this statistics can vary according to the year of your BMW X6, your driving, and the good functioning of your engine unit. A poorly looked after engine unit that releases unburned gases may forever alter your lambda sensor. One of the clues that can alert you of a defective lambda sensor on BMW X6 might be the engine unit light turns on, if you want to turn off the engine light of your BMW X6, do not hesitate to consult our dedicated article to see the process to stick to. The only effective way to make sure that you have a lambda sensor problem on your BMW X6 and to complete your car to the diagnostic case, for that do not hesitate to consult our tutorial which explains you BMW X6how to read the fault code of a BMW X6. Please note that if you have problems with one of your lambda sensors, the just remedy to resolve them will be to change the defective sensor.

How to change a lambda sensor on BMW X6?

And at last, we are going to focus on the correction of lambda sensor problems on BMW X6 , by describing how to replace a lambda sensor.

The replacement of a lambda sensor is quite basic to carry out and you will have the ability to do it yourself with a minimum 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 defective the second one risks to drop you quickly. To replace it, it will be required to put your BMW X6 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 BMW X6.
