Latest automobiles are progressively 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 automobiles. This is precisely the subject matter of our article content of the day, we are going to look at the problems of the lambda sensor on Buick Encore , this sensor also called oxygen sensor plays an necessary function. To find out, first, we are going to find out what a lambda probe is utilized for, then, what are the lambda sensor problems on Buick Encore and how to fix them.

What is a lambda purpose on Buick Encore?

So we start our content page with the interest of a lambda sensor on Buick Encore , we will first see what is the role of this probe and then how it functions.

Role of a lambda sensor on Buick Encore

First developed by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission standards. Also called oxygen sensor on Buick Encore , its objective is to regulate the amount of oxygen in the exhaust gases, this will allow the engine unit to modify the air/fuel mixture to reduce the pollution emitted by the motor vehicle and lower the car’s fuel consumption.

Lambda sensor procedure on Buick Encore

Before explaining you the different problems of lambda probe on Buick Encore , we will look a little more in detail at its working to allow you to understand precisely 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 job of controlling 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 standards there are now 2 lambda sensors, one before and one after the catalyst . The interest 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 improve the combustion .

Lambda sensor problem on Buick Encore

.
Finally, we are now going to attack the part you are absolutely most interested in this content page, how to handle it if you have a lambda sensor problem on Buick Encore . In a first step we will find out how to locate a lambda sensor HS and in a second step how to replace it.

How to know if a lambda sensor on Buick Encore is HS

.
It is necessary to know that a lambda sensor has in general a lifetime of 150 000 km , this statistics can vary according to the year of your Buick Encore, your driving, and the good functioning of your engine unit. A poorly maintained engine unit that produces unburned gases may permanently alter your lambda sensor. One of the clues that can notify you of a faulty lambda sensor on Buick Encore might be the engine unit light comes on, if you want to turn off the engine light of your Buick Encore, do not hesitate to visit our dedicated content page to see the process to stick to. The only effective technique to be certain that you have a lambda sensor problem on your Buick Encore and to pass your car to the diagnostic case, for that do not hesitate to consult our tutorial which explains you Buick Encorehow to read the fault code of a Buick Encore. Please note that if you have problems with one of your lambda sensors, the only solution to solve them will be to replace the faulty sensor.

How to replace a lambda sensor on Buick Encore?

And at last, we are going to concentrate on the correction of lambda sensor problems on Buick Encore , by describing how to replace a lambda sensor.

The replacement of a lambda sensor is quite very easy to carry out and you will be able to do it yourself with a minimal of tools and mechanical expertise. 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 necessary to put your Buick Encore 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 Encore.
