Modern cars 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 cars. This is exactly the subject of our content page of the day, we are going to look at the problems of the lambda sensor on Infiniti Q50 , this sensor also named oxygen sensor plays an important role. To find out, first, we are going to find out what a lambda probe is used for, then, what are the lambda sensor problems on Infiniti Q50 and how to fix them.

What is a lambda role on Infiniti Q50?

So we start our article with the interest of a lambda sensor on Infiniti Q50 , we will first discover what is the purpose of this probe and then how it functions.

Role of a lambda sensor on Infiniti Q50

First produced by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission standards. Also called oxygen sensor on Infiniti Q50 , 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 released by the car and lower the car’s fuel consumption.

Lambda sensor operation on Infiniti Q50

Before describing you the different problems of lambda probe on Infiniti Q50 , we will look a little more in detail at its working to allow you to understand precisely how it functions 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 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 only one lambda sensor needed before the catalyst, but with the arrival of more drastic standards 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 inserted into the engine unit to improve the combustion .

Lambda sensor issue on Infiniti Q50

.
Finally, we are now going to attack the section you are certainly most interested in this article, what to do if you have a lambda sensor issue on Infiniti Q50 . 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 Q50 is HS

.
It is important 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 Infiniti Q50, your driving, and the good functioning of your engine unit. A poorly looked after engine unit that produces unburned gases may completely damaged your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Infiniti Q50 may be the engine unit light comes on, if you want to turn off the engine light of your Infiniti Q50, do not hesitate to consult our dedicated article to discover the process to stick to. The only effective technique to be certain that you have a lambda sensor issue on your Infiniti Q50 and to complete your car to the diagnostic case, for that do not hesitate to consult our guide which explains you Infiniti Q50how to read the fault code of a Infiniti Q50. Please be aware that if you have problems with one of your lambda sensors, the only remedy to correct them will be to change the faulty sensor.

How to change a lambda sensor on Infiniti Q50?

And finally, we are going to focus on the correction of lambda sensor problems on Infiniti Q50 , by explaining how to replace a lambda sensor.

The replacement of a lambda sensor is quite simple 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 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 Q50 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 Q50.
