Latest 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 article content of the day, we are going to look at the problems of the lambda sensor on Ford Fusion , this sensor also named oxygen sensor plays an necessary function. 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 Ford Fusion and how to resolve them.

What is a lambda role on Ford Fusion?

So we begin our article with the benefit of a lambda sensor on Ford Fusion , we will first discover what is the purpose of this probe and then how it works.

Role of a lambda sensor on Ford Fusion

First developed by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission specifications. Also called oxygen sensor on Ford Fusion , its goal is to control 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 motor vehicle and lower the car’s fuel consumption.

Lambda sensor procedure on Ford Fusion

Before explaining you the different problems of lambda probe on Ford Fusion , we will look a little more in outline at its operation to allow you to discover exactly 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 task of controlling 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 needed before the catalyst, but with the arrival of more drastic specifications 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 inserted into the engine to optimize the combustion .

Lambda sensor problem on Ford Fusion

.
At last, we are now going to attack the section you are absolutely most interested in this article, what to do if you have a lambda sensor problem on Ford Fusion . In a first step we will discover how to locate a lambda sensor HS and in a second step how to change it.

How to know if a lambda sensor on Ford Fusion is HS

.
It is necessary to know that a lambda sensor has in general a lifetime of 150 000 km , this data can vary according to the year of your Ford Fusion, your driving, and the good functioning of your engine. A poorly maintained engine that emits unburned gases may permanently corrupt your lambda sensor. One of the clues that can notify you of a faulty lambda sensor on Ford Fusion might be the engine light comes on, if you want to turn off the engine light of your Ford Fusion, do not hesitate to seek advice from our dedicated article to discover the procedure to follow. The only effective technique to be sure that you have a lambda sensor problem on your Ford Fusion and to pass your car to the diagnostic case, for that do not hesitate to seek advice from our guide which explains you Ford Fusionhow to read the fault code of a Ford Fusion. Take note that if you have problems with one of your lambda sensors, the only remedy to resolve them will be to change the faulty sensor.

How to change a lambda sensor on Ford Fusion?

And finally, we are going to concentrate on the correction of lambda sensor problems on Ford Fusion , by explaining how to replace a lambda sensor.

The replacement of a lambda sensor is quite basic 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 faulty the second one risks to drop you fairly quickly. To replace it, it will be required to put your Ford Fusion 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 Ford Fusion.
