Recent cars are progressively built with new technologies, apart from the comfort of use it can provide, technology also 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 complications of the lambda sensor on GMC Acadia , this sensor also called 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 GMC Acadia and how to resolve them.

What is a lambda fonction on GMC Acadia?

So we start our content with the interest of a lambda sensor on GMC Acadia , we will first see what is the function of this probe and then how it functions.

Role of a lambda sensor on GMC Acadia

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

Lambda sensor operation on GMC Acadia

Before explaining you the different complications of lambda probe on GMC Acadia , we will look a little more in outline 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 informed you, a lambda probe has the task of managing the amount of oxygen present in the exhaust gases . One could naively think 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 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 inserted into the engine to improve the combustion .

Lambda sensor issue on GMC Acadia

.
At last, we are now going to attack the section you are certainly most interested in this content, what to do if you have a lambda sensor issue on GMC Acadia . 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 GMC Acadia is HS

.
It is important to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this data can differ according to the year of your GMC Acadia, your driving, and the good functioning of your engine. A poorly taken care of engine that releases unburned gases may permanently corrupt your lambda sensor. One of the clues that can notify you of a faulty lambda sensor on GMC Acadia might be the engine light turns on, if you want to turn off the engine light of your GMC Acadia, do not hesitate to visit our dedicated content to see the process to follow. The only effective technique to be sure that you have a lambda sensor issue on your GMC Acadia and to pass your car to the diagnostic case, for that do not hesitate to seek advice from our tutorial which explains you GMC Acadiahow to read the fault code of a GMC Acadia. Please be aware that if you have complications with one of your lambda sensors, the just solution to resolve them will be to replace the faulty sensor.

How to replace a lambda sensor on GMC Acadia?

And at last, we are going to concentrate on the correction of lambda sensor problems on GMC Acadia , by detailing how to replace a lambda sensor.

The replacement of a lambda sensor is quite basic to accomplish and you will have the ability 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 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 quickly. To replace it, it will be necessary to put your GMC Acadia 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 GMC Acadia.
