Recent vehicles are more and more pre-loaded 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 vehicles. This is exactly the subject of our content page of the day, we are going to look at the problems of the lambda sensor on Ford Flex , this sensor also called oxygen sensor plays an essential role. 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 Flex and how to resolve them.
What is a lambda task on Ford Flex?
So we start our article with the benefit of a lambda sensor on Ford Flex , we will first see what is the task of this probe and then how it functions.
Role of a lambda sensor on Ford Flex
First designed by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission specifications. As well called oxygen sensor on Ford Flex , its task is to control the amount of oxygen in the exhaust gases, this will enable the engine to adapt the air/fuel mixture to reduce the pollution released by the car and lower the car’s fuel consumption.
Lambda sensor procedure on Ford Flex
Before explaining you the different problems of lambda probe on Ford Flex , we will look a little more in outline at its functioning to allow you to discover exactly how it functions and thus to consider more serenely the correction of a problem related to it.
As we informed you, a lambda probe has the job of controlling the amount of oxygen present in the exhaust gases . One could naively believe 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 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 improve the combustion .
Lambda sensor issue on Ford Flex
.
At last, we are now going to attack the part you are certainly most enthusiastic about this article, how to handle it if you have a lambda sensor issue on Ford Flex . In a first step we will find out how to find a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Ford Flex is HS
.
It is essential 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 Flex, your driving, and the good working of your engine. A poorly maintained engine that releases unburned gases may forever corrupt your lambda sensor. One of the clues that can warn you of a defective lambda sensor on Ford Flex might be the engine light comes on, if you want to turn off the engine light of your Ford Flex, do not hesitate to seek advice from our dedicated article to see the procedure to follow. The only effective method to make sure that you have a lambda sensor issue on your Ford Flex and to complete your car to the diagnostic case, for that do not hesitate to seek advice from our guide which explains you Ford Flexhow to read the fault code of a Ford Flex. Take note that if you have problems with one of your lambda sensors, the only remedy to resolve them will be to replace the defective sensor.
How to replace a lambda sensor on Ford Flex?
And finally, we are going to focus on the correction of lambda sensor problems on Ford Flex , by detailing how to replace a lambda sensor.
The replacement of a lambda sensor is quite very easy to perform and you will have the ability to do it yourself with a lowest of tools and mechanical knowledge. 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 quickly. To replace it, it will be necessary to put your Ford Flex 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 Flex.
