Recent cars are progressively 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 released by our cars. This is exactly the subject of our article of the day, we are going to look at the problems of the lambda sensor on Nissan Sentra , this sensor also called oxygen sensor plays an necessary purpose. To find out, first, we are going to find out what a lambda probe is utilized for, then, what are the lambda sensor problems on Nissan Sentra and how to fix them.
What is a lambda role on Nissan Sentra?
So we begin our content page with the benefit of a lambda sensor on Nissan Sentra , we will first see what is the function of this probe and then how it works.
Role of a lambda sensor on Nissan Sentra
First developed by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission requirements. As well called oxygen sensor on Nissan Sentra , its mission is to control the amount of oxygen in the exhaust gases, this will enable the engine unit to modify the air/fuel mixture to reduce the pollution released by the car and lower the car’s fuel consumption.
Lambda sensor procedure on Nissan Sentra
Before explaining you the different problems of lambda probe on Nissan Sentra , we will look a little more in detail at its functioning to allow you to understand 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 managing the amount of oxygen present in the exhaust gases . One could naively think 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 required 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 benefit is to have more exact data by compiling the two probes. These data are sent to the ECU which will adapt the quantity of air and gasoline inserted into the engine unit to optimize the combustion .
Lambda sensor issue on Nissan Sentra
.
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 Sentra . In a first step we will see how to find a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Nissan Sentra is HS
.
It is necessary to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this info can differ according to the year of your Nissan Sentra, your driving, and the good functioning of your engine unit. A poorly maintained engine unit that produces unburned gases may permanently alter your lambda sensor. One of the clues that can notify you of a defective lambda sensor on Nissan Sentra may be the engine unit light comes on, if you want to turn off the engine light of your Nissan Sentra, do not think twice to consult our dedicated content page to see the procedure to follow. The only effective technique to make sure that you have a lambda sensor issue on your Nissan Sentra and to pass your car to the diagnostic case, for that do not think twice to consult our guide which explains you Nissan Sentrahow to read the fault code of a Nissan Sentra. Please note that if you have problems with one of your lambda sensors, the only solution to resolve them will be to replace the defective sensor.
How to replace a lambda sensor on Nissan Sentra?
And finally, we are going to concentrate on the correction of lambda sensor problems on Nissan Sentra , 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 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 fairly quickly. To replace it, it will be required to put your Nissan Sentra 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 problems with your lambda sensor on Nissan Sentra.
