Latest cars are increasingly equipped with new technologies, apart from the comfort of use it can bring, technology also has the advantage of saving fuel or reducing the pollution emitted by our cars. This is precisely the subject matter of our article of the day, we are going to look at the problems of the lambda sensor on Lexus NX , this sensor also known as 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 Lexus NX and how to solve them.
What is a lambda role on Lexus NX?
So we begin our content with the benefit of a lambda sensor on Lexus NX , we will first see what is the task of this probe and then how it functions.
Role of a lambda sensor on Lexus NX
First designed 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 Lexus NX , its mission is to control the amount of oxygen in the exhaust gases, this will enable the engine unit to change the air/fuel mixture to reduce the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.
Lambda sensor process on Lexus NX
Before describing you the different problems of lambda probe on Lexus NX , we will look a little more in detail at its working to allow you to understand exactly how it functions and thus to consider more serenely the correction of a problem related to it.
As we informed you, a lambda probe has the task of controlling the amount of oxygen present in the exhaust gases . One could naively presume 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 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 exact 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 unit to improve the combustion .

.
At last, we are now going to attack the part you are certainly most keen on this content, what to do if you have a lambda sensor problem on Lexus NX . In a first step we will see how to locate a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Lexus NX is HS
.
It is necessary to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this statistics can differ according to the year of your Lexus NX, your driving, and the good working of your engine unit. A poorly looked after engine unit that produces unburned gases may forever damaged your lambda sensor. One of the clues that can warn you of a faulty lambda sensor on Lexus NX may be the engine unit light turns on, if you want to turn off the engine light of your Lexus NX, do not hesitate to consult our dedicated content to see the process to stick to. The only effective technique to be sure that you have a lambda sensor problem on your Lexus NX and to complete your car to the diagnostic case, for that do not hesitate to consult our tutorial which explains you Lexus NXhow to read the fault code of a Lexus NX. Take note that if you have problems with one of your lambda sensors, the just solution to correct them will be to replace the faulty sensor.
How to replace a lambda sensor on Lexus NX?
And at last, we are going to concentrate on the correction of lambda sensor problems on Lexus NX , by detailing how to replace a lambda sensor.
The replacement of a lambda sensor is quite basic to carry out and you will be able 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 required to put your Lexus NX 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 Lexus NX.
