Latest automobiles 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 emitted by our automobiles. This is exactly the subject of our content page of the day, we are going to look at the complications of the lambda sensor on Infiniti QX50 , this sensor also known as oxygen sensor plays an important function. To find out, first, we are going to identify what a lambda probe is used for, then, what are the lambda sensor complications on Infiniti QX50 and how to fix them.

What is a lambda task on Infiniti QX50?

So we begin our content page with the interest of a lambda sensor on Infiniti QX50 , we will first see what is the job of this probe and then how it functions.

Role of a lambda sensor on Infiniti QX50

First created by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission specifications. As well called oxygen sensor on Infiniti QX50 , its goal is to regulate the amount of oxygen in the exhaust gases, this will enable the engine unit to modify the air/fuel mixture to lower the pollution emitted by the car and reduce the car’s fuel consumption.

Lambda sensor operation on Infiniti QX50

Before explaining you the different complications of lambda probe on Infiniti QX50 , we will look a little more in detail at its working to allow you to figure out exactly how it functions and thus to consider more serenely the correction of a problem related to it.
As we told you, a lambda probe has the job of managing the amount of oxygen present in the exhaust gases . One could naively presume 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 just one lambda sensor required 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 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 optimize the combustion .

Lambda sensor issue on Infiniti QX50

.
At last, we are now going to attack the section you are obviously most keen on this content page, what to do if you have a lambda sensor issue on Infiniti QX50 . In a first step we will find out how to locate a lambda sensor HS and in a second step how to replace it.

How to know if a lambda sensor on Infiniti QX50 is HS

.
It is important to know that a lambda sensor has in general a lifetime of 150 000 km , this data can vary according to the year of your Infiniti QX50, your driving, and the good functioning of your engine unit. A poorly looked after 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 Infiniti QX50 might be the engine unit light comes on, if you want to turn off the engine light of your Infiniti QX50, do not hesitate to consult our dedicated content page to see the process to follow. The only effective method to be sure that you have a lambda sensor issue on your Infiniti QX50 and to pass your car to the diagnostic case, for that do not hesitate to consult our guide which explains you Infiniti QX50how to read the fault code of a Infiniti QX50. Please note that if you have complications with one of your lambda sensors, the just remedy to correct them will be to replace the defective sensor.

How to replace a lambda sensor on Infiniti QX50?

And finally, we are going to focus on the correction of lambda sensor problems on Infiniti QX50 , by detailing how to replace a lambda sensor.

The replacement of a lambda sensor is quite basic to perform and you will be able to do it yourself with a lowest 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 Infiniti QX50 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 Infiniti QX50.
