Latest vehicles are progressively furnished 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 vehicles. This is precisely the subject matter of our article of the day, we are going to look at the complications of the lambda sensor on Nissan Leaf , this sensor also known as 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 Leaf and how to solve them.
What is a lambda fonction on Nissan Leaf?
So we start our content with the interest of a lambda sensor on Nissan Leaf , we will first discover what is the role of this probe and then how it works.
Role of a lambda sensor on Nissan Leaf
First created by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on Nissan Leaf , its task is to control the amount of oxygen in the exhaust gases, this will allow the engine to change the air/fuel mixture to decrease the pollution released by the car and reduce the car’s fuel consumption.
Lambda sensor operation on Nissan Leaf
Before explaining you the different complications of lambda probe on Nissan Leaf , we will look a little more in outline at its working to allow you to discover exactly how it works and thus to consider more serenely the correction of a problem associated with it.
As we explained to you, a lambda probe has the job of controlling 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 needed before the catalyst, but with the arrival of more drastic requirements 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 modify the quantity of air and gasoline injected into the engine to improve the combustion .

.
Finally, we are now going to attack the section you are absolutely most interested in this content, what to do if you have a lambda sensor problem on Nissan Leaf . In a first step we will see how to identify a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Nissan Leaf is HS
.
It is essential to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this data can fluctuate according to the year of your Nissan Leaf, your driving, and the good performance of your engine. A poorly looked after engine that emits unburned gases may permanently corrupt your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Nissan Leaf might be the engine light turns on, if you want to turn off the engine light of your Nissan Leaf, do not hesitate to visit our dedicated content to discover the procedure to stick to. The only effective technique to be certain that you have a lambda sensor problem on your Nissan Leaf and to pass your car to the diagnostic case, for that do not hesitate to consult our tutorial which explains you Nissan Leafhow to read the fault code of a Nissan Leaf. Please note that if you have complications with one of your lambda sensors, the just remedy to resolve them will be to replace the faulty sensor.
How to replace a lambda sensor on Nissan Leaf?
And finally, we are going to concentrate on the correction of lambda sensor problems on Nissan Leaf , by describing how to replace a lambda sensor.
The replacement of a lambda sensor is quite very easy to carry out and you will have the ability to do it yourself with a minimal of tools and mechanical expertise. 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 faulty the second one risks to drop you quickly. To replace it, it will be necessary to put your Nissan Leaf 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 Leaf.
