Latest 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 exactly the subject matter of our content of the day, we are going to look at the problems of the lambda sensor on Cadillac CTS , 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 Cadillac CTS and how to solve them.
What is a lambda task on Cadillac CTS?
So we begin our content page with the benefit of a lambda sensor on Cadillac CTS , we will first see what is the job of this probe and then how it functions.
Role of a lambda sensor on Cadillac CTS
First designed 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 Cadillac CTS , its objective is to control the amount of oxygen in the exhaust gases, this will allow the engine to modify the air/fuel mixture to decrease the pollution released by the motor vehicle and lower the car’s fuel consumption.
Lambda sensor procedure on Cadillac CTS
Before describing you the different problems of lambda probe on Cadillac CTS , we will look a little more in detail at its working to allow you to figure out exactly how it functions and thus to consider more serenely the correction of a problem associated with 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 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 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 injected into the engine to improve the combustion .
Lambda sensor issue on Cadillac CTS
.
At last, we are now going to attack the part you are obviously most interested in this content page, what to do if you have a lambda sensor issue on Cadillac CTS . In a first step we will see how to identify a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Cadillac CTS is HS
.
It is essential to know that a lambda sensor has generally a lifetime of 150 000 km , this info can vary according to the year of your Cadillac CTS, your driving, and the good working of your engine. A poorly maintained engine that emits unburned gases may completely corrupt your lambda sensor. One of the clues that can notify you of a faulty lambda sensor on Cadillac CTS may be the engine light turns on, if you want to turn off the engine light of your Cadillac CTS, do not think twice to consult 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 Cadillac CTS and to pass your car to the diagnostic case, for that do not think twice to consult our tutorial which explains you Cadillac CTShow to read the fault code of a Cadillac CTS. Take note that if you have problems with one of your lambda sensors, the only solution to resolve them will be to replace the faulty sensor.
How to replace a lambda sensor on Cadillac CTS?
And at last, we are going to focus on the correction of lambda sensor problems on Cadillac CTS , by detailing how to replace a lambda sensor.
The replacement of a lambda sensor is quite simple to accomplish and you will be able 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 replace 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 CTS 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 Cadillac CTS.
