Latest vehicles are progressively equipped 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 emitted by our vehicles. This is precisely the subject matter of our content of the day, we are going to look at the problems of the lambda sensor on Bmw 1 series , this sensor as well named oxygen sensor plays an necessary role. To find out, first, we are going to find out what a lambda probe is employed for, then, what are the lambda sensor problems on Bmw 1 series and how to fix them.

What is a lambda task on Bmw 1 series?

So we begin our content with the interest of a lambda sensor on Bmw 1 series , we will first discover what is the job of this probe and then how it works.

Role of a lambda sensor on Bmw 1 series

First developed 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 1 series , its task is to control the amount of oxygen in the exhaust gases, this will allow the engine to modify the air/fuel mixture to lower the pollution emitted by the car and lower the car’s fuel consumption.

Lambda sensor procedure on Bmw 1 series

Before describing you the different problems of lambda probe on Bmw 1 series , we will look a little more in outline at its functioning to allow you to figure out precisely how it works and thus to consider more serenely the correction of a problem associated with 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 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 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 to improve the combustion .

Lambda sensor problem on Bmw 1 series

.
Finally, we are now going to attack the section you are undoubtedly most enthusiastic about this content, what to do if you have a lambda sensor problem on Bmw 1 series . In a first step we will find out how to locate a lambda sensor HS and in a second step how to replace it.

How to know if a lambda sensor on Bmw 1 series is HS

.
It is necessary to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this info can differ according to the year of your Bmw 1 series, your driving, and the good performance of your engine. A poorly looked after engine that releases unburned gases may forever damaged your lambda sensor. One of the clues that can notify you of a defective lambda sensor on Bmw 1 series may be the engine light turns on, if you want to turn off the engine light of your Bmw 1 series, do not hesitate to seek advice from our dedicated content to discover the process to follow. The only effective technique to ensure that you have a lambda sensor problem on your Bmw 1 series and to pass your car to the diagnostic case, for that do not hesitate to consult our tutorial which explains you Bmw 1 serieshow to read the fault code of a Bmw 1 series. Take note that if you have problems with one of your lambda sensors, the just solution to correct them will be to replace the defective sensor.

How to replace a lambda sensor on Bmw 1 series?

And finally, we are going to focus on the correction of lambda sensor problems on Bmw 1 series , by detailing how to replace a lambda sensor.

The replacement of a lambda sensor is quite basic to carry out and you will be able to do it yourself with a minimal 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 defective the second one risks to drop you fairly quickly. To replace it, it will be required to put your Bmw 1 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 problems with your lambda sensor on Bmw 1 series.
