Modern cars are more and more equipped 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 exactly the subject of our article of the day, we are going to look at the problems of the lambda sensor on Buick Enclave , this sensor also called oxygen sensor plays an important purpose. To find out, first, we are going to identify what a lambda probe is employed for, then, what are the lambda sensor problems on Buick Enclave and how to solve them.
What is a lambda task on Buick Enclave?
So we begin our content page with the benefit of a lambda sensor on Buick Enclave , we will first discover what is the role of this probe and then how it functions.
Role of a lambda sensor on Buick Enclave
First designed by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on Buick Enclave , its objective is to regulate the amount of oxygen in the exhaust gases, this will enable the engine unit to modify the air/fuel mixture to decrease the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.
Lambda sensor operation on Buick Enclave
Before describing you the different problems of lambda probe on Buick Enclave , we will look a little more in outline at its working to allow you to discover exactly how it functions and thus to consider more serenely the correction of a problem related to 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 measured 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 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 unit to optimize the combustion .

.
Finally, we are now going to attack the section you are absolutely most enthusiastic about this content page, how to proceed if you have a lambda sensor issue on Buick Enclave . 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 Buick Enclave is HS
.
It is important to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this data can vary according to the year of your Buick Enclave, your driving, and the good performance of your engine unit. A poorly looked after engine unit that emits unburned gases may completely corrupt your lambda sensor. One of the clues that can warn you of a defective lambda sensor on Buick Enclave may be the engine unit light comes on, if you want to turn off the engine light of your Buick Enclave, do not think twice to consult our dedicated content page to discover the procedure to stick to. The only effective way to be sure that you have a lambda sensor issue on your Buick Enclave and to pass your car to the diagnostic case, for that do not think twice to consult our guide which explains you Buick Enclavehow to read the fault code of a Buick Enclave. Take note that if you have problems with one of your lambda sensors, the only solution to resolve them will be to change the defective sensor.
How to change a lambda sensor on Buick Enclave?
And finally, we are going to concentrate on the correction of lambda sensor problems on Buick Enclave , by detailing how to replace a lambda sensor.
The replacement of a lambda sensor is quite basic to accomplish 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 defective the second one risks to drop you fairly quickly. To replace it, it will be necessary to put your Buick Enclave 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 Buick Enclave.
