Modern vehicles are increasingly equipped with new technologies, apart from the comfort of use it can provide, technology also has the advantage of saving fuel or reducing the pollution emitted by our vehicles. This is exactly the subject of our content page of the day, we are going to look at the complications of the lambda sensor on BMW 7 Series , 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 used for, then, what are the lambda sensor complications on BMW 7 Series and how to solve them.
What is a lambda fonction on BMW 7 Series?
So we begin our content with the interest of a lambda sensor on BMW 7 Series , we will first discover what is the task of this probe and then how it functions.
Role of a lambda sensor on BMW 7 Series
First created 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 BMW 7 Series , its objective is to regulate the amount of oxygen in the exhaust gases, this will enable the engine to change the air/fuel mixture to decrease the pollution emitted by the car and lower the car’s fuel consumption.
Lambda sensor procedure on BMW 7 Series
Before describing you the different complications of lambda probe on BMW 7 Series , 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 related to it.
As we told you, a lambda probe has the job of controlling the amount of oxygen present in the exhaust gases . One could naively presume 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 only 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 interest is to have more precise data by compiling the two probes. These data are sent to the ECU which will adapt the quantity of air and gasoline inserted into the engine to optimize the combustion .
Lambda sensor problem on BMW 7 Series
.
Finally, we are now going to attack the section you are undoubtedly most interested in this content, how to handle it if you have a lambda sensor problem on BMW 7 Series . In a first step we will see how to find a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on BMW 7 Series is HS
.
It is essential to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this data can differ according to the year of your BMW 7 Series, your driving, and the good functioning of your engine. A poorly looked after engine that emits unburned gases may completely alter your lambda sensor. One of the clues that can notify you of a faulty lambda sensor on BMW 7 Series might be the engine light turns on, if you want to turn off the engine light of your BMW 7 Series, do not hesitate to seek advice from our dedicated content to discover the procedure to follow. The only effective method to be certain that you have a lambda sensor problem on your BMW 7 Series and to complete your car to the diagnostic case, for that do not hesitate to seek advice from our tutorial which explains you BMW 7 Serieshow to read the fault code of a BMW 7 Series. Take note that if you have complications with one of your lambda sensors, the only remedy to resolve them will be to replace the faulty sensor.
How to replace a lambda sensor on BMW 7 Series?
And at last, we are going to focus on the correction of lambda sensor problems on BMW 7 Series , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite very easy to carry out and you will have the ability to do it yourself with a lowest of tools and mechanical knowledge. 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 faulty the second one risks to drop you quickly. To replace it, it will be necessary to put your BMW 7 Series 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 BMW 7 Series.
