Latest 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 content of the day, we are going to look at the complications of the lambda sensor on Infiniti QX60 , this sensor also known as oxygen sensor plays an important purpose. To find out, first, we are going to find out what a lambda probe is employed for, then, what are the lambda sensor complications on Infiniti QX60 and how to fix them.
What is a lambda role on Infiniti QX60?
So we start our content page with the interest of a lambda sensor on Infiniti QX60 , we will first see what is the job of this probe and then how it functions.
Role of a lambda sensor on Infiniti QX60
First created 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 QX60 , its goal is to regulate the amount of oxygen in the exhaust gases, this will allow the engine unit to modify the air/fuel mixture to lower the pollution released by the car and reduce the car’s fuel consumption.
Lambda sensor process on Infiniti QX60
Before describing you the different complications of lambda probe on Infiniti QX60 , we will look a little more in outline at its working to allow you to figure out 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 job of managing the amount of oxygen present in the exhaust gases . One could naively believe 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 required 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 adapt the quantity of air and gasoline inserted into the engine unit to optimize the combustion .
Lambda sensor issue on Infiniti QX60
.
Finally, we are now going to attack the part you are obviously most enthusiastic about this content page, how to proceed if you have a lambda sensor issue on Infiniti QX60 . 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 QX60 is HS
.
It is important to know that a lambda sensor has in general a lifetime of 150 000 km , this statistics can fluctuate according to the year of your Infiniti QX60, your driving, and the good performance of your engine unit. A poorly taken care of engine unit that releases unburned gases may forever alter your lambda sensor. One of the clues that can notify you of a defective lambda sensor on Infiniti QX60 may be the engine unit light turns on, if you want to turn off the engine light of your Infiniti QX60, do not hesitate to seek advice from our dedicated content page to see the process to stick to. The only effective technique to be certain that you have a lambda sensor issue on your Infiniti QX60 and to complete your car to the diagnostic case, for that do not hesitate to seek advice from our tutorial which explains you Infiniti QX60how to read the fault code of a Infiniti QX60. Take note that if you have complications with one of your lambda sensors, the only remedy to solve them will be to change the defective sensor.
How to change a lambda sensor on Infiniti QX60?
And finally, we are going to concentrate on the correction of lambda sensor problems on Infiniti QX60 , by describing how to replace a lambda sensor.
The replacement of a lambda sensor is quite very easy to execute and you will be able to do it yourself with a minimum of tools and mechanical know-how. 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 defective the second one risks to drop you quickly. To replace it, it will be required to put your Infiniti QX60 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 complications with your lambda sensor on Infiniti QX60.
