Modern cars are increasingly built with new technologies, apart from the comfort of use it can bring, technology also has the advantage of saving fuel or reducing the pollution emitted by our cars. This is precisely the subject matter of our article of the day, we are going to look at the complications of the lambda sensor on Cadillac Escalade , this sensor also known as oxygen sensor plays an important function. To find out, first, we are going to identify what a lambda probe is employed for, then, what are the lambda sensor complications on Cadillac Escalade and how to resolve them.

What is a lambda task on Cadillac Escalade?

So we start our article with the benefit of a lambda sensor on Cadillac Escalade , we will first see what is the function of this probe and then how it works.

Role of a lambda sensor on Cadillac Escalade

First produced by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission specifications. As well called oxygen sensor on Cadillac Escalade , its goal is to regulate 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 car and reduce the car’s fuel consumption.

Lambda sensor operation on Cadillac Escalade

Before explaining you the different complications of lambda probe on Cadillac Escalade , we will look a little more in detail at its operation to allow you to discover precisely how it works and thus to consider more serenely the correction of a problem related to 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 believe that this data is calculated 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 specifications there are now 2 lambda sensors, one before and one after the catalyst . The benefit is to have more exact data by compiling the two probes. These data are sent to the ECU which will adjust the quantity of air and gasoline inserted into the engine to optimize the combustion .

Lambda sensor issue on Cadillac Escalade

.
At last, we are now going to attack the section you are certainly most keen on this article, how to proceed if you have a lambda sensor issue on Cadillac Escalade . 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 Cadillac Escalade is HS

.
It is important to know that a lambda sensor has generally a lifetime of 150 000 km , this data can vary according to the year of your Cadillac Escalade, your driving, and the good functioning of your engine. A poorly maintained engine that emits unburned gases may completely corrupt your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Cadillac Escalade might be the engine light turns on, if you want to turn off the engine light of your Cadillac Escalade, do not think twice to visit our dedicated article to see the process to stick to. The only effective way to be certain that you have a lambda sensor issue on your Cadillac Escalade and to complete your car to the diagnostic case, for that do not think twice to consult our guide which explains you Cadillac Escaladehow to read the fault code of a Cadillac Escalade. Please be aware that if you have complications with one of your lambda sensors, the only solution to correct them will be to change the faulty sensor.

How to change a lambda sensor on Cadillac Escalade?

And finally, we are going to concentrate on the correction of lambda sensor problems on Cadillac Escalade , by detailing how to replace a lambda sensor.

The replacement of a lambda sensor is quite basic to execute and you will be able to do it yourself with a minimal 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 faulty the second one risks to drop you quickly. To replace it, it will be required to put your Cadillac Escalade 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 Escalade.
