Recent cars are increasingly furnished 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 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 Mercury Milan , this sensor also named oxygen sensor plays an important purpose. To find out, first, we are going to identify what a lambda probe is utilized for, then, what are the lambda sensor problems on Mercury Milan and how to fix them.
What is a lambda role on Mercury Milan?
So we begin our content page with the interest of a lambda sensor on Mercury Milan , we will first see what is the task of this probe and then how it works.
Role of a lambda sensor on Mercury Milan
First created by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission standards. As well called oxygen sensor on Mercury Milan , its task is to regulate the amount of oxygen in the exhaust gases, this will enable the engine to adapt the air/fuel mixture to reduce the pollution emitted by the car and reduce the car’s fuel consumption.
Lambda sensor process on Mercury Milan
Before explaining you the different problems of lambda probe on Mercury Milan , we will look a little more in detail at its functioning to allow you to understand exactly 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 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 required 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 exact data by compiling the two probes. These data are sent to the ECU which will adapt the quantity of air and gasoline injected into the engine to improve the combustion .
Lambda sensor issue on Mercury Milan
.
At last, we are now going to attack the section you are obviously most keen on this content page, how to handle it if you have a lambda sensor issue on Mercury Milan . In a first step we will discover how to find a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Mercury Milan is HS
.
It is important to know that a lambda sensor has in general a lifetime of 150 000 km , this data can fluctuate according to the year of your Mercury Milan, your driving, and the good performance of your engine. A poorly looked after engine that emits unburned gases may completely damaged your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Mercury Milan may be the engine light turns on, if you want to turn off the engine light of your Mercury Milan, do not hesitate to consult our dedicated content page to see the procedure to stick to. The only effective method to be certain that you have a lambda sensor issue on your Mercury Milan and to pass your car to the diagnostic case, for that do not hesitate to consult our guide which explains you Mercury Milanhow to read the fault code of a Mercury Milan. Please note that if you have problems with one of your lambda sensors, the only solution to resolve them will be to change the faulty sensor.
How to change a lambda sensor on Mercury Milan?
And at last, we are going to focus on the correction of lambda sensor problems on Mercury Milan , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite basic to perform and you will have the ability to do it yourself with a minimal 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 faulty the second one risks to drop you fairly quickly. To replace it, it will be necessary to put your Mercury Milan 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 Mercury Milan.
