Recent 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 precisely the subject matter of our content of the day, we are going to look at the problems of the lambda sensor on Land Rover LR4 , this sensor also known as oxygen sensor plays an important role. 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 Land Rover LR4 and how to fix them.
What is a lambda fonction on Land Rover LR4?
So we start our article with the interest of a lambda sensor on Land Rover LR4 , we will first discover what is the function of this probe and then how it works.
Role of a lambda sensor on Land Rover LR4
First created by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission requirements. As well called oxygen sensor on Land Rover LR4 , its objective is to regulate the amount of oxygen in the exhaust gases, this will allow the engine to adapt the air/fuel mixture to reduce the pollution released by the motor vehicle and reduce the car’s fuel consumption.

Before explaining you the different problems of lambda probe on Land Rover LR4 , we will look a little more in outline at its functioning to allow you to figure out precisely how it works 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 managing 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 just one lambda sensor needed 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 interest 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 to optimize the combustion .

.
At last, we are now going to attack the part you are absolutely most interested in this article, how to proceed if you have a lambda sensor problem on Land Rover LR4 . In a first step we will see how to identify a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Land Rover LR4 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 Land Rover LR4, your driving, and the good working of your engine. A poorly looked after engine that produces unburned gases may forever damaged your lambda sensor. One of the clues that can notify you of a defective lambda sensor on Land Rover LR4 might be the engine light comes on, if you want to turn off the engine light of your Land Rover LR4, do not hesitate to consult our dedicated article to discover the procedure to follow. The only effective method to be sure that you have a lambda sensor problem on your Land Rover LR4 and to pass your car to the diagnostic case, for that do not hesitate to consult our tutorial which explains you Land Rover LR4how to read the fault code of a Land Rover LR4. Please note that if you have problems with one of your lambda sensors, the just remedy to solve them will be to change the defective sensor.
How to change a lambda sensor on Land Rover LR4?
And at last, we are going to focus on the correction of lambda sensor problems on Land Rover LR4 , by describing how to replace a lambda sensor.
The replacement of a lambda sensor is quite simple to carry out and you will be able to do it yourself with a lowest of tools and mechanical knowledge. 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 quickly. To replace it, it will be required to put your Land Rover LR4 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 Land Rover LR4.
