Latest cars are increasingly equipped with new technologies, apart from the comfort of use it can bring, technology also has the advantage of saving fuel or reducing the pollution released by our cars. This is precisely the subject of our article of the day, we are going to look at the complications of the lambda sensor on Ford Focus , this sensor also named oxygen sensor plays an important purpose. To find out, first, we are going to find out what a lambda probe is utilized for, then, what are the lambda sensor complications on Ford Focus and how to fix them.
What is a lambda task on Ford Focus?
So we start our content with the benefit of a lambda sensor on Ford Focus , we will first discover what is the job of this probe and then how it functions.
Role of a lambda sensor on Ford Focus
First created by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission specifications. As well called oxygen sensor on Ford Focus , its objective is to regulate the amount of oxygen in the exhaust gases, this will enable the engine to adapt the air/fuel mixture to lower the pollution released by the motor vehicle and lower the car’s fuel consumption.
Lambda sensor operation on Ford Focus
Before explaining you the different complications of lambda probe on Ford Focus , we will look a little more in outline at its functioning to allow you to understand exactly how it functions and thus to consider more serenely the correction of a problem related to 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 think 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 just one lambda sensor required 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 precise 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 Ford Focus
.
At last, we are now going to attack the section you are absolutely most keen on this content, how to proceed if you have a lambda sensor issue on Ford Focus . In a first step we will find out how to identify a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Ford Focus is HS
.
It is important to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this info can vary according to the year of your Ford Focus, your driving, and the good working of your engine. A poorly taken care of engine that emits unburned gases may forever alter your lambda sensor. One of the clues that can warn you of a defective lambda sensor on Ford Focus might be the engine light turns on, if you want to turn off the engine light of your Ford Focus, do not think twice to visit our dedicated content to discover the procedure to follow. The only effective technique to make sure that you have a lambda sensor issue on your Ford Focus and to complete your car to the diagnostic case, for that do not think twice to consult our tutorial which explains you Ford Focushow to read the fault code of a Ford Focus. Take note that if you have complications 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 Ford Focus?
And finally, we are going to concentrate on the correction of lambda sensor problems on Ford Focus , by describing how to replace a lambda sensor.
The replacement of a lambda sensor is quite very easy to perform and you will be able 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 Ford Focus 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 complications with your lambda sensor on Ford Focus.
