Modern automobiles are more and more equipped 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 released by our automobiles. This is precisely the subject of our article of the day, we are going to look at the complications of the lambda sensor on Nissan Xterra , this sensor as well called oxygen sensor plays an essential function. 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 Nissan Xterra and how to resolve them.
What is a lambda purpose on Nissan Xterra?
So we begin our article with the benefit of a lambda sensor on Nissan Xterra , we will first discover what is the task of this probe and then how it works.
Role of a lambda sensor on Nissan Xterra
First created by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission specifications. As well called oxygen sensor on Nissan Xterra , its objective is to control the amount of oxygen in the exhaust gases, this will allow the engine unit to adapt the air/fuel mixture to decrease the pollution released by the motor vehicle and lower the car’s fuel consumption.
Lambda sensor operation on Nissan Xterra
Before describing you the different complications of lambda probe on Nissan Xterra , we will look a little more in detail at its functioning 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 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 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 specifications 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 adjust the quantity of air and gasoline injected into the engine unit to optimize the combustion .

.
Finally, we are now going to attack the part you are certainly most enthusiastic about this article, how to handle it if you have a lambda sensor issue on Nissan Xterra . In a first step we will find out how to locate a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Nissan Xterra 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 Xterra, your driving, and the good performance of your engine unit. A poorly looked after engine unit that releases unburned gases may completely corrupt your lambda sensor. One of the clues that can warn you of a defective lambda sensor on Nissan Xterra may be the engine unit light comes on, if you want to turn off the engine light of your Nissan Xterra, do not think twice to consult our dedicated article to discover the process to follow. The only effective technique to be sure that you have a lambda sensor issue on your Nissan Xterra and to complete your car to the diagnostic case, for that do not think twice to seek advice from our tutorial which explains you Nissan Xterrahow to read the fault code of a Nissan Xterra. 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 Xterra?
And at last, we are going to focus on the correction of lambda sensor problems on Nissan Xterra , by describing how to replace a lambda sensor.
The replacement of a lambda sensor is quite basic to carry out and you will have the ability 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 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 required to put your Nissan Xterra 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 Xterra.
