Recent automobiles are increasingly built 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 of our article content of the day, we are going to look at the problems of the lambda sensor on Infiniti M , this sensor as well named oxygen sensor plays an essential role. To find out, first, we are going to identify what a lambda probe is employed for, then, what are the lambda sensor problems on Infiniti M and how to resolve them.

What is a lambda task on Infiniti M?

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

Role of a lambda sensor on Infiniti M

First developed by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission requirements. As well called oxygen sensor on Infiniti M , its objective is to regulate 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 motor vehicle and lower the car’s fuel consumption.

Lambda sensor operation on Infiniti M

Before describing you the different problems of lambda probe on Infiniti M , we will look a little more in outline at its operation to allow you to figure out exactly how it works and thus to consider more serenely the correction of a problem related to it.
As we informed 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 measured 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 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 optimize the combustion .

Lambda sensor issue on Infiniti M

.
At last, we are now going to attack the part you are obviously most keen on this content page, how to handle it if you have a lambda sensor issue on Infiniti M . In a first step we will discover how to identify a lambda sensor HS and in a second step how to replace it.

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

.
It is essential to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this statistics can vary according to the year of your Infiniti M, 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 notify you of a defective lambda sensor on Infiniti M may be the engine unit light turns on, if you want to turn off the engine light of your Infiniti M, do not hesitate to visit our dedicated content page to see the process to stick to. The only effective method to make sure that you have a lambda sensor issue on your Infiniti M and to complete your car to the diagnostic case, for that do not hesitate to seek advice from our guide which explains you Infiniti Mhow to read the fault code of a Infiniti M. Please note that if you have problems with one of your lambda sensors, the only solution to correct them will be to replace the defective sensor.

How to replace a lambda sensor on Infiniti M?

And finally, we are going to focus on the correction of lambda sensor problems on Infiniti M , by explaining 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 defective the second one risks to drop you fairly quickly. To replace it, it will be necessary to put your Infiniti M 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 M.
