Modern cars are increasingly equipped with new technologies, apart from the comfort of use it can provide, technology as well 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 Yukon , this sensor as well named oxygen sensor plays an essential function. To find out, first, we are going to identify what a lambda probe is used for, then, what are the lambda sensor complications on GMC Yukon and how to solve them.
What is a lambda purpose on GMC Yukon?
So we begin our article with the benefit of a lambda sensor on GMC Yukon , we will first see what is the purpose of this probe and then how it functions.
Role of a lambda sensor on GMC Yukon
First developed by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission standards. Also called oxygen sensor on GMC Yukon , its objective is to control the amount of oxygen in the exhaust gases, this will enable the engine unit to change the air/fuel mixture to reduce the pollution released by the motor vehicle and reduce the car’s fuel consumption.
Lambda sensor process on GMC Yukon
Before describing you the different complications of lambda probe on GMC Yukon , we will look a little more in detail at its functioning to allow you to figure out precisely 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 think 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 just one lambda sensor required 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 benefit is to have more exact 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 unit to improve the combustion .
Lambda sensor problem on GMC Yukon
.
At last, we are now going to attack the section you are undoubtedly most interested in this article, what to do if you have a lambda sensor problem on GMC Yukon . In a first step we will find out 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 Yukon is HS
.
It is essential to know that a lambda sensor has in general a lifetime of 150 000 km , this data can differ according to the year of your GMC Yukon, your driving, and the good working of your engine unit. A poorly taken care of engine unit that produces unburned gases may completely damaged your lambda sensor. One of the clues that can notify you of a faulty lambda sensor on GMC Yukon may be the engine unit light comes on, if you want to turn off the engine light of your GMC Yukon, do not think twice to consult our dedicated article to see the procedure to stick to. The only effective way to make sure that you have a lambda sensor problem on your GMC Yukon and to pass your car to the diagnostic case, for that do not think twice to consult our tutorial which explains you GMC Yukonhow to read the fault code of a GMC Yukon. Please be aware that if you have complications with one of your lambda sensors, the just remedy to correct them will be to replace the faulty sensor.
How to replace a lambda sensor on GMC Yukon?
And at last, we are going to focus on the correction of lambda sensor problems on GMC Yukon , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite basic to execute 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 fairly quickly. To replace it, it will be necessary to put your GMC Yukon 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 Yukon.
