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 precisely the subject matter of our article of the day, we are going to look at the problems of the lambda sensor on Ford Explorer , this sensor also named oxygen sensor plays an essential 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 Ford Explorer and how to solve them.
What is a lambda fonction on Ford Explorer?
So we begin our content page with the interest of a lambda sensor on Ford Explorer , we will first see what is the task of this probe and then how it works.
Role of a lambda sensor on Ford Explorer
First developed by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on Ford Explorer , its goal is to control the amount of oxygen in the exhaust gases, this will enable the engine unit to adapt the air/fuel mixture to decrease the pollution released by the motor vehicle and lower the car’s fuel consumption.
Lambda sensor operation on Ford Explorer
Before explaining you the different problems of lambda probe on Ford Explorer , we will look a little more in outline at its working to allow you to figure out 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 needed 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 Ford Explorer
.
Finally, we are now going to attack the part you are undoubtedly most interested in this content page, how to handle it if you have a lambda sensor issue on Ford Explorer . In a first step we will see 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 Explorer is HS
.
It is essential to know that a lambda sensor has in general a lifetime of 150 000 km , this info can fluctuate according to the year of your Ford Explorer, your driving, and the good performance of your engine unit. A poorly maintained engine unit that releases unburned gases may forever alter your lambda sensor. One of the clues that can notify you of a defective lambda sensor on Ford Explorer may be the engine unit light comes on, if you want to turn off the engine light of your Ford Explorer, do not think twice to seek advice from our dedicated content page to see the process to follow. The only effective technique to be certain that you have a lambda sensor issue on your Ford Explorer and to pass your car to the diagnostic case, for that do not think twice to seek advice from our tutorial which explains you Ford Explorerhow to read the fault code of a Ford Explorer. Please be aware that if you have problems with one of your lambda sensors, the only remedy to solve them will be to replace the defective sensor.
How to replace a lambda sensor on Ford Explorer?
And at last, we are going to concentrate on the correction of lambda sensor problems on Ford Explorer , by detailing how to replace a lambda sensor.
The replacement of a lambda sensor is quite simple to execute and you will have the ability to do it yourself with a minimum 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 Explorer 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 Explorer.
