Recent 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 article of the day, we are going to look at the complications of the lambda sensor on Nissan Pathfinder , this sensor also named 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 Pathfinder and how to solve them.

What is a lambda task on Nissan Pathfinder?

So we start our content page with the benefit of a lambda sensor on Nissan Pathfinder , we will first see what is the function of this probe and then how it functions.

Role of a lambda sensor on Nissan Pathfinder

First designed 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 Nissan Pathfinder , its objective is to control the amount of oxygen in the exhaust gases, this will allow the engine to adapt the air/fuel mixture to reduce the pollution emitted by the car and lower the car’s fuel consumption.

Lambda sensor operation on Nissan Pathfinder

Before describing you the different complications of lambda probe on Nissan Pathfinder , we will look a little more in outline at its working to allow you to discover precisely how it functions and thus to consider more serenely the correction of a problem associated with it.
As we informed 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 determined 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 benefit 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 inserted into the engine to improve the combustion .

Lambda sensor issue on Nissan Pathfinder

.
Finally, we are now going to attack the part you are certainly most enthusiastic about this content page, what to do if you have a lambda sensor issue on Nissan Pathfinder . 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 Pathfinder is HS

.
It is essential to know that a lambda sensor has in general a lifetime of 150 000 km , this info can fluctuate according to the year of your Nissan Pathfinder, your driving, and the good working of your engine. A poorly maintained engine that produces unburned gases may forever damaged your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Nissan Pathfinder may be the engine light turns on, if you want to turn off the engine light of your Nissan Pathfinder, do not think twice to consult our dedicated content page to see the procedure to stick to. The only effective method to be sure that you have a lambda sensor issue on your Nissan Pathfinder and to complete your car to the diagnostic case, for that do not think twice to consult our guide which explains you Nissan Pathfinderhow to read the fault code of a Nissan Pathfinder. Take note that if you have complications with one of your lambda sensors, the just solution to solve them will be to change the faulty sensor.

How to change a lambda sensor on Nissan Pathfinder?

And finally, we are going to focus on the correction of lambda sensor problems on Nissan Pathfinder , by describing 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 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 faulty the second one risks to drop you quickly. To replace it, it will be necessary to put your Nissan Pathfinder 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 Pathfinder.
