Modern automobiles 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 released by our automobiles. This is precisely the subject of our article of the day, we are going to look at the problems of the lambda sensor on Mini Countryman , this sensor as well called oxygen sensor plays an necessary role. To find out, first, we are going to identify what a lambda probe is employed for, then, what are the lambda sensor problems on Mini Countryman and how to fix them.

What is a lambda purpose on Mini Countryman?

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

Role of a lambda sensor on Mini Countryman

First created 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 Mini Countryman , its mission is to regulate the amount of oxygen in the exhaust gases, this will allow the engine unit to modify the air/fuel mixture to reduce the pollution released by the car and reduce the car’s fuel consumption.

Lambda sensor operation on Mini Countryman

Before describing you the different problems of lambda probe on Mini Countryman , we will look a little more in detail 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 informed you, a lambda probe has the task of managing the amount of oxygen present in the exhaust gases . One could naively believe that this data is determined 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 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 unit to improve the combustion .

Lambda sensor issue on Mini Countryman

.
At last, we are now going to attack the part you are absolutely most keen on this article, how to proceed if you have a lambda sensor issue on Mini Countryman . In a first step we will discover how to identify a lambda sensor HS and in a second step how to change it.

How to know if a lambda sensor on Mini Countryman is HS

.
It is necessary to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this info can fluctuate according to the year of your Mini Countryman, your driving, and the good working of your engine unit. A poorly looked after engine unit that emits unburned gases may permanently corrupt your lambda sensor. One of the clues that can notify you of a defective lambda sensor on Mini Countryman may be the engine unit light turns on, if you want to turn off the engine light of your Mini Countryman, do not think twice to consult our dedicated article to see the procedure to stick to. The only effective method to ensure that you have a lambda sensor issue on your Mini Countryman and to complete your car to the diagnostic case, for that do not think twice to consult our guide which explains you Mini Countrymanhow to read the fault code of a Mini Countryman. Please be aware that if you have problems with one of your lambda sensors, the only remedy to resolve them will be to change the defective sensor.

How to change a lambda sensor on Mini Countryman?

And at last, we are going to focus on the correction of lambda sensor problems on Mini Countryman , by explaining how to replace a lambda sensor.

The replacement of a lambda sensor is quite simple to accomplish and you will be able 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 defective the second one risks to drop you fairly quickly. To replace it, it will be required to put your Mini Countryman 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 Mini Countryman.
