Latest cars are increasingly built with new technologies, apart from the comfort of use it can bring, technology also has the advantage of saving fuel or reducing the pollution released by our cars. This is precisely the subject of our content of the day, we are going to look at the complications of the lambda sensor on Nissan Armada , this sensor also called oxygen sensor plays an essential purpose. To find out, first, we are going to find out what a lambda probe is employed for, then, what are the lambda sensor complications on Nissan Armada and how to resolve them.
What is a lambda task on Nissan Armada?
So we start our content page with the interest of a lambda sensor on Nissan Armada , we will first discover what is the job of this probe and then how it functions.
Role of a lambda sensor on Nissan Armada
First produced by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission specifications. Also called oxygen sensor on Nissan Armada , its objective is to regulate the amount of oxygen in the exhaust gases, this will enable the engine to modify the air/fuel mixture to reduce the pollution released by the motor vehicle and lower the car’s fuel consumption.
Lambda sensor process on Nissan Armada
Before explaining you the different complications of lambda probe on Nissan Armada , we will look a little more in outline at its functioning to allow you to figure out precisely 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 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 only 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 interest is to have more precise 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 to optimize the combustion .

.
Finally, we are now going to attack the part you are undoubtedly most interested in this content page, what to do if you have a lambda sensor issue on Nissan Armada . In a first step we will discover how to identify a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Nissan Armada is HS
.
It is essential to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this info can vary according to the year of your Nissan Armada, your driving, and the good performance of your engine. A poorly maintained engine that produces unburned gases may completely damaged your lambda sensor. One of the clues that can notify you of a defective lambda sensor on Nissan Armada may be the engine light turns on, if you want to turn off the engine light of your Nissan Armada, do not hesitate to seek advice from our dedicated content page to discover the process to stick to. The only effective method to be sure that you have a lambda sensor issue on your Nissan Armada and to pass your car to the diagnostic case, for that do not hesitate to seek advice from our guide which explains you Nissan Armadahow to read the fault code of a Nissan Armada. Please note that if you have complications with one of your lambda sensors, the only solution to correct them will be to change the defective sensor.
How to change a lambda sensor on Nissan Armada?
And finally, we are going to focus on the correction of lambda sensor problems on Nissan Armada , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite simple to carry out and you will be able to do it yourself with a minimal of tools and mechanical know-how. 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 quickly. To replace it, it will be necessary to put your Nissan Armada 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 Nissan Armada.
