Latest automobiles are more and more pre-loaded with new technologies, apart from the comfort of use it can bring, technology as well has the advantage of saving fuel or reducing the pollution released by our automobiles. This is exactly the subject matter of our content page of the day, we are going to look at the problems of the lambda sensor on Infiniti QX30 , this sensor as well called 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 problems on Infiniti QX30 and how to solve them.

What is a lambda task on Infiniti QX30?

So we start our article with the interest of a lambda sensor on Infiniti QX30 , we will first see what is the function of this probe and then how it works.

Role of a lambda sensor on Infiniti QX30

First designed 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 Infiniti QX30 , its goal is to regulate the amount of oxygen in the exhaust gases, this will enable the engine unit to change the air/fuel mixture to lower the pollution released by the car and lower the car’s fuel consumption.

Lambda sensor process on Infiniti QX30

Before explaining you the different problems of lambda probe on Infiniti QX30 , we will look a little more in detail at its functioning to allow you to figure out precisely how it works and thus to consider more serenely the correction of a problem related to it.
As we explained to you, a lambda probe has the task of controlling 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 interest 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 improve the combustion .

Lambda sensor issue on Infiniti QX30

.
Finally, we are now going to attack the part you are absolutely most enthusiastic about this article, how to proceed if you have a lambda sensor issue on Infiniti QX30 . In a first step we will find out how to identify a lambda sensor HS and in a second step how to change it.

How to know if a lambda sensor on Infiniti QX30 is HS

.
It is essential to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this statistics can fluctuate according to the year of your Infiniti QX30, your driving, and the good performance of your engine unit. A poorly looked after engine unit that releases unburned gases may permanently alter your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Infiniti QX30 may be the engine unit light turns on, if you want to turn off the engine light of your Infiniti QX30, do not think twice to visit our dedicated article to see the procedure to stick to. The only effective technique to be sure that you have a lambda sensor issue on your Infiniti QX30 and to complete your car to the diagnostic case, for that do not think twice to consult our guide which explains you Infiniti QX30how to read the fault code of a Infiniti QX30. Please note that if you have problems with one of your lambda sensors, the only remedy to resolve them will be to change the faulty sensor.

How to change a lambda sensor on Infiniti QX30?

And finally, we are going to concentrate on the correction of lambda sensor problems on Infiniti QX30 , 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 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 Infiniti QX30 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 Infiniti QX30.
