Latest vehicles are more and more 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 emitted by our vehicles. This is precisely the subject matter of our content page of the day, we are going to look at the complications of the lambda sensor on Audi Q5 , this sensor also named oxygen sensor plays an important purpose. To find out, first, we are going to find out what a lambda probe is utilized for, then, what are the lambda sensor complications on Audi Q5 and how to solve them.
What is a lambda task on Audi Q5?
So we start our article with the interest of a lambda sensor on Audi Q5 , we will first see what is the job of this probe and then how it functions.
Role of a lambda sensor on Audi Q5
First created 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 Audi Q5 , its task is to regulate the amount of oxygen in the exhaust gases, this will enable the engine to adapt the air/fuel mixture to reduce the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.
Lambda sensor procedure on Audi Q5
Before explaining you the different complications of lambda probe on Audi Q5 , we will look a little more in detail at its functioning 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 task of managing the amount of oxygen present in the exhaust gases . One could naively think 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 requirements there are now 2 lambda sensors, one before and one after the catalyst . The interest is to have more precise data by compiling the two probes. These data are sent to the ECU which will modify the quantity of air and gasoline inserted into the engine to optimize the combustion .
Lambda sensor issue on Audi Q5
.
Finally, we are now going to attack the part you are certainly most keen on this article, what to do if you have a lambda sensor issue on Audi Q5 . In a first step we will discover how to locate a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Audi Q5 is HS
.
It is important to know that a lambda sensor has in general a lifetime of 150 000 km , this info can differ according to the year of your Audi Q5, your driving, and the good performance of your engine. A poorly maintained engine that releases unburned gases may completely corrupt your lambda sensor. One of the clues that can notify you of a defective lambda sensor on Audi Q5 may be the engine light comes on, if you want to turn off the engine light of your Audi Q5, do not hesitate to consult our dedicated article to see the procedure to stick to. The only effective method to ensure that you have a lambda sensor issue on your Audi Q5 and to complete your car to the diagnostic case, for that do not hesitate to seek advice from our tutorial which explains you Audi Q5how to read the fault code of a Audi Q5. Take note that if you have complications with one of your lambda sensors, the only remedy to solve them will be to replace the defective sensor.
How to replace a lambda sensor on Audi Q5?
And finally, we are going to concentrate on the correction of lambda sensor problems on Audi Q5 , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite simple to perform 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 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 quickly. To replace it, it will be necessary to put your Audi Q5 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 Audi Q5.
