Modern cars are increasingly pre-loaded with new technologies, apart from the comfort of use it can bring, technology also has the advantage of saving fuel or reducing the pollution released by our cars. This is exactly the subject of our article content of the day, we are going to look at the problems of the lambda sensor on GMC Savana , this sensor also named oxygen sensor plays an important purpose. To find out, first, we are going to find out what a lambda probe is employed for, then, what are the lambda sensor problems on GMC Savana and how to solve them.
What is a lambda fonction on GMC Savana?
So we start our article with the interest of a lambda sensor on GMC Savana , we will first discover what is the task of this probe and then how it functions.
Role of a lambda sensor on GMC Savana
First designed by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission specifications. Also called oxygen sensor on GMC Savana , its mission is to regulate the amount of oxygen in the exhaust gases, this will allow the engine to modify the air/fuel mixture to reduce the pollution released by the motor vehicle and lower the car’s fuel consumption.
Lambda sensor operation on GMC Savana
Before explaining you the different problems of lambda probe on GMC Savana , we will look a little more in outline at its functioning to allow you to understand exactly how it functions 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 controlling 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 specifications there are now 2 lambda sensors, one before and one after the catalyst . The interest 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 injected into the engine to improve the combustion .

.
Finally, we are now going to attack the part you are undoubtedly most enthusiastic about this article, how to proceed if you have a lambda sensor problem on GMC Savana . In a first step we will discover how to find a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on GMC Savana is HS
.
It is important to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this statistics can differ according to the year of your GMC Savana, your driving, and the good working of your engine. A poorly maintained engine that emits unburned gases may forever damaged your lambda sensor. One of the clues that can alert you of a defective lambda sensor on GMC Savana may be the engine light comes on, if you want to turn off the engine light of your GMC Savana, do not hesitate to visit our dedicated article to discover the procedure to stick to. The only effective technique to be certain that you have a lambda sensor problem on your GMC Savana and to complete your car to the diagnostic case, for that do not hesitate to consult our tutorial which explains you GMC Savanahow to read the fault code of a GMC Savana. Please be aware that if you have problems with one of your lambda sensors, the just remedy to solve them will be to replace the defective sensor.
How to replace a lambda sensor on GMC Savana?
And at last, we are going to concentrate on the correction of lambda sensor problems on GMC Savana , 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 lowest 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 defective the second one risks to drop you fairly quickly. To replace it, it will be necessary to put your GMC Savana 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 GMC Savana.
