Recent cars are more and more built with new technologies, apart from the comfort of use it can provide, technology as well has the advantage of saving fuel or reducing the pollution emitted by our cars. This is exactly the subject of our article content of the day, we are going to look at the problems of the lambda sensor on Ford Fiesta , this sensor as well named oxygen sensor plays an necessary purpose. 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 Fiesta and how to fix them.
What is a lambda fonction on Ford Fiesta?
So we begin our content page with the benefit of a lambda sensor on Ford Fiesta , we will first see what is the job of this probe and then how it works.
Role of a lambda sensor on Ford Fiesta
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. Also called oxygen sensor on Ford Fiesta , its mission is to control the amount of oxygen in the exhaust gases, this will enable the engine unit to modify the air/fuel mixture to reduce the pollution emitted by the car and reduce the car’s fuel consumption.
Lambda sensor procedure on Ford Fiesta
Before explaining you the different problems of lambda probe on Ford Fiesta , we will look a little more in detail at its working to allow you to figure out precisely how it works and thus to consider more serenely the correction of a problem related to it.
As we explained to 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 calculated 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 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 adapt the quantity of air and gasoline inserted into the engine unit to optimize the combustion .
Lambda sensor issue on Ford Fiesta
.
At last, we are now going to attack the section you are undoubtedly most interested in this content page, what to do if you have a lambda sensor issue on Ford Fiesta . In a first step we will discover 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 Fiesta is HS
.
It is necessary to know that a lambda sensor has generally a lifetime of 150 000 km , this statistics can differ according to the year of your Ford Fiesta, your driving, and the good performance of your engine unit. A poorly taken care of engine unit that emits unburned gases may forever damaged your lambda sensor. One of the clues that can warn you of a defective lambda sensor on Ford Fiesta might be the engine unit light comes on, if you want to turn off the engine light of your Ford Fiesta, do not think twice to consult our dedicated content page to see the procedure to stick to. The only effective method to ensure that you have a lambda sensor issue on your Ford Fiesta and to pass your car to the diagnostic case, for that do not think twice to consult our guide which explains you Ford Fiestahow to read the fault code of a Ford Fiesta. Please be aware that if you have problems with one of your lambda sensors, the just solution to resolve them will be to replace the defective sensor.
How to replace a lambda sensor on Ford Fiesta?
And finally, we are going to concentrate on the correction of lambda sensor problems on Ford Fiesta , by detailing how to replace a lambda sensor.
The replacement of a lambda sensor is quite very easy to carry out and you will have the ability 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 required to put your Ford Fiesta 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 Fiesta.
