Recent vehicles 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 vehicles. This is exactly the subject matter of our content page of the day, we are going to look at the problems of the lambda sensor on Cadillac SRX , this sensor also 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 SRX and how to resolve them.

What is a lambda fonction on Cadillac SRX?

So we start our content page with the benefit of a lambda sensor on Cadillac SRX , we will first discover what is the function of this probe and then how it works.

Role of a lambda sensor on Cadillac SRX

First produced by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission specifications. Also called oxygen sensor on Cadillac SRX , its goal is to control the amount of oxygen in the exhaust gases, this will enable the engine unit to adapt the air/fuel mixture to decrease the pollution emitted by the motor vehicle and lower the car’s fuel consumption.

Lambda sensor process on Cadillac SRX

Before describing you the different problems of lambda probe on Cadillac SRX , we will look a little more in outline at its working 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 informed 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 just 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 injected into the engine unit to optimize the combustion .

Lambda sensor issue on Cadillac SRX

.
Finally, we are now going to attack the part you are obviously most interested in this content page, how to handle it if you have a lambda sensor issue on Cadillac SRX . 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 SRX is HS

.
It is essential 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 Cadillac SRX, your driving, and the good performance of your engine unit. A poorly looked after engine unit that produces unburned gases may completely alter your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Cadillac SRX might be the engine unit light turns on, if you want to turn off the engine light of your Cadillac SRX, do not think twice to seek advice from our dedicated content page to discover the process to stick to. The only effective method to be sure that you have a lambda sensor issue on your Cadillac SRX and to pass your car to the diagnostic case, for that do not think twice to consult our tutorial which explains you Cadillac SRXhow to read the fault code of a Cadillac SRX. Please be aware that if you have problems with one of your lambda sensors, the just remedy to correct them will be to change the faulty sensor.

How to change a lambda sensor on Cadillac SRX?

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

The replacement of a lambda sensor is quite simple to accomplish and you will have the ability 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 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 SRX 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 SRX.
