Recent cars are increasingly 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 cars. This is precisely the subject matter of our content of the day, we are going to look at the complications of the lambda sensor on Audi Q3 , this sensor as well known as oxygen sensor plays an necessary 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 Audi Q3 and how to resolve them.
What is a lambda purpose on Audi Q3?
So we start our content with the interest of a lambda sensor on Audi Q3 , we will first discover what is the task of this probe and then how it functions.
Role of a lambda sensor on Audi Q3
First developed by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission standards. Also called oxygen sensor on Audi Q3 , its task is to control the amount of oxygen in the exhaust gases, this will allow the engine unit to adapt the air/fuel mixture to lower the pollution released by the motor vehicle and reduce the car’s fuel consumption.
Lambda sensor process on Audi Q3
Before explaining you the different complications of lambda probe on Audi Q3 , we will look a little more in detail at its working to allow you to figure out precisely how it functions and thus to consider more serenely the correction of a problem associated with it.
As we told 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 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 modify the quantity of air and gasoline inserted into the engine unit to improve the combustion .
Lambda sensor problem on Audi Q3
.
Finally, we are now going to attack the section you are undoubtedly most keen on this content, how to proceed if you have a lambda sensor problem on Audi Q3 . In a first step we will find out how to find a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Audi Q3 is HS
.
It is necessary to know that a lambda sensor has in general a lifetime of 150 000 km , this data can fluctuate according to the year of your Audi Q3, your driving, and the good working of your engine unit. A poorly looked after engine unit that releases unburned gases may forever corrupt your lambda sensor. One of the clues that can notify you of a defective lambda sensor on Audi Q3 might be the engine unit light turns on, if you want to turn off the engine light of your Audi Q3, do not think twice to consult our dedicated content to discover the process to follow. The only effective way to be sure that you have a lambda sensor problem on your Audi Q3 and to pass your car to the diagnostic case, for that do not think twice to seek advice from our guide which explains you Audi Q3how to read the fault code of a Audi Q3. Take note that if you have complications with one of your lambda sensors, the only solution to correct them will be to change the defective sensor.
How to change a lambda sensor on Audi Q3?
And finally, we are going to focus on the correction of lambda sensor problems on Audi Q3 , by describing how to replace a lambda sensor.
The replacement of a lambda sensor is quite very easy to accomplish and you will have the ability to do it yourself with a minimum 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 defective the second one risks to drop you quickly. To replace it, it will be required to put your Audi Q3 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 Q3.
