Recent automobiles are progressively furnished 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 automobiles. This is exactly the subject of our article content of the day, we are going to look at the complications of the lambda sensor on Fiat 500X , this sensor as well called oxygen sensor plays an essential role. To find out, first, we are going to find out what a lambda probe is used for, then, what are the lambda sensor complications on Fiat 500X and how to fix them.
What is a lambda fonction on Fiat 500X?
So we begin our content page with the interest of a lambda sensor on Fiat 500X , we will first discover what is the job of this probe and then how it works.
Role of a lambda sensor on Fiat 500X
First designed by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on Fiat 500X , its objective is to regulate the amount of oxygen in the exhaust gases, this will allow the engine unit to modify the air/fuel mixture to lower the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.
Lambda sensor operation on Fiat 500X
Before explaining you the different complications of lambda probe on Fiat 500X , we will look a little more in detail at its operation to allow you to discover exactly 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 job 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 just one lambda sensor required 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 adjust the quantity of air and gasoline injected into the engine unit to optimize the combustion .
Lambda sensor issue on Fiat 500X
.
At last, we are now going to attack the section you are obviously most interested in this content page, how to handle it if you have a lambda sensor issue on Fiat 500X . 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 Fiat 500X is HS
.
It is essential to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this statistics can vary according to the year of your Fiat 500X, your driving, and the good working of your engine unit. A poorly looked after engine unit that produces unburned gases may completely alter your lambda sensor. One of the clues that can alert you of a defective lambda sensor on Fiat 500X might be the engine unit light turns on, if you want to turn off the engine light of your Fiat 500X, do not hesitate to consult our dedicated content page to discover the procedure to follow. The only effective method to be certain that you have a lambda sensor issue on your Fiat 500X and to pass your car to the diagnostic case, for that do not hesitate to consult our tutorial which explains you Fiat 500Xhow to read the fault code of a Fiat 500X. Take note that if you have complications with one of your lambda sensors, the just solution to solve them will be to replace the defective sensor.
How to replace a lambda sensor on Fiat 500X?
And finally, we are going to concentrate on the correction of lambda sensor problems on Fiat 500X , by describing how to replace a lambda sensor.
The replacement of a lambda sensor is quite simple to perform and you will be able to do it yourself with a minimal 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 quickly. To replace it, it will be necessary to put your Fiat 500X 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 Fiat 500X.
