Recent cars are more and more equipped with new technologies, apart from the comfort of use it can provide, technology also has the advantage of saving fuel or reducing the pollution released by our cars. This is exactly the subject of our content of the day, we are going to look at the complications of the lambda sensor on Alfa Romeo Giulia , this sensor also named oxygen sensor plays an essential function. To find out, first, we are going to find out what a lambda probe is utilized for, then, what are the lambda sensor complications on Alfa Romeo Giulia and how to fix them.

What is a lambda task on Alfa Romeo Giulia?

So we begin our article with the benefit of a lambda sensor on Alfa Romeo Giulia , we will first discover what is the role of this probe and then how it functions.

Role of a lambda sensor on Alfa Romeo Giulia

First created by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission standards. Also called oxygen sensor on Alfa Romeo Giulia , its mission is to control the amount of oxygen in the exhaust gases, this will allow the engine unit to change the air/fuel mixture to lower the pollution released by the car and reduce the car’s fuel consumption.

Lambda sensor process on Alfa Romeo Giulia

Before describing you the different complications of lambda probe on Alfa Romeo Giulia , we will look a little more in outline at its operation to allow you to understand precisely how it functions 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 think 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 standards 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 modify the quantity of air and gasoline inserted into the engine unit to improve the combustion .

.
Finally, we are now going to attack the section you are obviously most enthusiastic about this article, what to do if you have a lambda sensor problem on Alfa Romeo Giulia . In a first step we will see how to locate a lambda sensor HS and in a second step how to change it.

How to know if a lambda sensor on Alfa Romeo Giulia is HS

.
It is essential to know that a lambda sensor has generally a lifetime of 150 000 km , this statistics can fluctuate according to the year of your Alfa Romeo Giulia, your driving, and the good functioning of your engine unit. A poorly maintained engine unit that produces unburned gases may forever damaged your lambda sensor. One of the clues that can warn you of a faulty lambda sensor on Alfa Romeo Giulia may be the engine unit light turns on, if you want to turn off the engine light of your Alfa Romeo Giulia, do not hesitate to consult our dedicated article to discover the process to follow. The only effective method to ensure that you have a lambda sensor problem on your Alfa Romeo Giulia and to complete your car to the diagnostic case, for that do not hesitate to consult our tutorial which explains you Alfa Romeo Giuliahow to read the fault code of a Alfa Romeo Giulia. Take note that if you have complications with one of your lambda sensors, the only solution to correct them will be to change the faulty sensor.

How to change a lambda sensor on Alfa Romeo Giulia?

And at last, we are going to focus on the correction of lambda sensor problems on Alfa Romeo Giulia , by explaining 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 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 faulty the second one risks to drop you fairly quickly. To replace it, it will be necessary to put your Alfa Romeo Giulia 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 Alfa Romeo Giulia.
