Recent cars are more and more built with new technologies, apart from the comfort of use it can provide, technology also has the advantage of saving fuel or reducing the pollution emitted by our cars. This is exactly the subject of our article of the day, we are going to look at the complications of the lambda sensor on Fiat 500 , 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 complications on Fiat 500 and how to resolve them.

What is a lambda fonction on Fiat 500?

So we begin our content page with the benefit of a lambda sensor on Fiat 500 , we will first see what is the task of this probe and then how it functions.

Role of a lambda sensor on Fiat 500

First created by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission requirements. As well called oxygen sensor on Fiat 500 , its task is to control the amount of oxygen in the exhaust gases, this will enable the engine to change the air/fuel mixture to reduce the pollution emitted by the motor vehicle and lower the car’s fuel consumption.

Lambda sensor operation on Fiat 500

Before explaining you the different complications of lambda probe on Fiat 500 , we will look a little more in outline at its working to allow you to figure out precisely how it functions and thus to consider more serenely the correction of a problem associated with 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 calculated 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 requirements 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 adapt the quantity of air and gasoline inserted into the engine to improve the combustion .

Lambda sensor problem on Fiat 500

.
Finally, we are now going to attack the section you are absolutely most enthusiastic about this content page, what to do if you have a lambda sensor problem on Fiat 500 . In a first step we will see how to find a lambda sensor HS and in a second step how to change it.

How to know if a lambda sensor on Fiat 500 is HS

.
It is essential to know that a lambda sensor has generally a lifetime of 150 000 km , this info can differ according to the year of your Fiat 500, your driving, and the good working of your engine. A poorly maintained engine that releases unburned gases may completely corrupt your lambda sensor. One of the clues that can warn you of a defective lambda sensor on Fiat 500 may be the engine light turns on, if you want to turn off the engine light of your Fiat 500, do not think twice to seek advice from our dedicated content page to see the procedure to follow. The only effective way to ensure that you have a lambda sensor problem on your Fiat 500 and to complete your car to the diagnostic case, for that do not think twice to seek advice from our tutorial which explains you Fiat 500how to read the fault code of a Fiat 500. Take note that if you have complications with one of your lambda sensors, the only remedy to correct them will be to change the defective sensor.

How to change a lambda sensor on Fiat 500?

And finally, we are going to concentrate on the correction of lambda sensor problems on Fiat 500 , by detailing 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 lowest of tools and mechanical expertise. A lambda sensor is worth between 25 and 50€ , it is better to change 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 Fiat 500 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 500.
