Recent vehicles are progressively furnished 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 article content of the day, we are going to look at the problems of the lambda sensor on BMW i3 , this sensor as well named oxygen sensor plays an essential function. To find out, first, we are going to find out what a lambda probe is used for, then, what are the lambda sensor problems on BMW i3 and how to resolve them.
What is a lambda role on BMW i3?
So we begin our content with the benefit of a lambda sensor on BMW i3 , we will first discover what is the task of this probe and then how it works.
Role of a lambda sensor on BMW i3
First developed by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on BMW i3 , its goal is to regulate the amount of oxygen in the exhaust gases, this will allow the engine to adapt the air/fuel mixture to decrease the pollution emitted by the car and lower the car’s fuel consumption.
Lambda sensor procedure on BMW i3
Before explaining you the different problems of lambda probe on BMW i3 , we will look a little more in outline at its working to allow you to discover precisely how it works and thus to consider more serenely the correction of a problem associated with it.
As we explained to you, a lambda probe has the task 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 only one lambda sensor needed 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 benefit is to have more exact data by compiling the two probes. These data are sent to the ECU which will adjust the quantity of air and gasoline injected into the engine to improve the combustion .
Lambda sensor issue on BMW i3
.
Finally, we are now going to attack the part you are obviously most interested in this content, how to proceed if you have a lambda sensor issue on BMW i3 . 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 i3 is HS
.
It is essential to know that a lambda sensor has in general a lifetime of 150 000 km , this statistics can fluctuate according to the year of your BMW i3, your driving, and the good working of your engine. A poorly taken care of engine that emits unburned gases may forever damaged your lambda sensor. One of the clues that can alert you of a defective lambda sensor on BMW i3 may be the engine light turns on, if you want to turn off the engine light of your BMW i3, do not think twice to visit our dedicated content to discover the procedure to stick to. The only effective way to make sure that you have a lambda sensor issue on your BMW i3 and to complete your car to the diagnostic case, for that do not think twice to consult our guide which explains you BMW i3how to read the fault code of a BMW i3. Please be aware that if you have problems with one of your lambda sensors, the only remedy to correct them will be to replace the defective sensor.
How to replace a lambda sensor on BMW i3?
And at last, we are going to focus on the correction of lambda sensor problems on BMW i3 , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite simple to accomplish 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 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 necessary to put your BMW i3 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 i3.
