Modern automobiles are more and more built 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 automobiles. This is precisely the subject of our content page of the day, we are going to look at the complications of the lambda sensor on Cadillac ATS , this sensor also named 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 Cadillac ATS and how to resolve them.
What is a lambda role on Cadillac ATS?
So we start our content with the benefit of a lambda sensor on Cadillac ATS , we will first see what is the purpose of this probe and then how it works.
Role of a lambda sensor on Cadillac ATS
First created by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on Cadillac ATS , its objective is to control the amount of oxygen in the exhaust gases, this will enable the engine to adapt the air/fuel mixture to lower the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.
Lambda sensor operation on Cadillac ATS
Before explaining you the different complications of lambda probe on Cadillac ATS , we will look a little more in outline at its working to allow you to understand precisely how it works and thus to consider more serenely the correction of a problem associated with it.
As we told 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 measured upstream of the combustion but it is on the contrary measured at the engine outlet . With the EURO 1 standard there was just one lambda sensor required 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 benefit 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 .

.
At last, we are now going to attack the section you are absolutely most keen on this content, how to handle it if you have a lambda sensor problem on Cadillac ATS . In a first step we will see how to find a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Cadillac ATS is HS
.
It is necessary to know that a lambda sensor has in general a lifetime of 150 000 km , this data can vary according to the year of your Cadillac ATS, your driving, and the good working of your engine. A poorly maintained engine that releases unburned gases may completely corrupt your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Cadillac ATS may be the engine light turns on, if you want to turn off the engine light of your Cadillac ATS, do not think twice to seek advice from our dedicated content to see the process to stick to. The only effective way to be sure that you have a lambda sensor problem on your Cadillac ATS and to pass your car to the diagnostic case, for that do not think twice to seek advice from our tutorial which explains you Cadillac ATShow to read the fault code of a Cadillac ATS. Please be aware that if you have complications with one of your lambda sensors, the just solution to correct them will be to change the faulty sensor.
How to change a lambda sensor on Cadillac ATS?
And at last, we are going to focus on the correction of lambda sensor problems on Cadillac ATS , by detailing how to replace a lambda sensor.
The replacement of a lambda sensor is quite very easy to execute and you will have the ability to do it yourself with a minimum of tools and mechanical knowledge. 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 fairly quickly. To replace it, it will be required to put your Cadillac ATS 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 Cadillac ATS.
