Recent automobiles are progressively equipped with new technologies, apart from the comfort of use it can bring, technology as well has the advantage of saving fuel or reducing the pollution emitted by our automobiles. This is precisely the subject of our content page of the day, we are going to look at the problems of the lambda sensor on Jeep Liberty , this sensor as well called oxygen sensor plays an essential function. To find out, first, we are going to identify what a lambda probe is employed for, then, what are the lambda sensor problems on Jeep Liberty and how to solve them.
What is a lambda role on Jeep Liberty?
So we start our article with the benefit of a lambda sensor on Jeep Liberty , we will first see what is the function of this probe and then how it functions.
Role of a lambda sensor on Jeep Liberty
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 Jeep Liberty , its task is to control the amount of oxygen in the exhaust gases, this will allow the engine to modify the air/fuel mixture to decrease the pollution emitted by the motor vehicle and lower the car’s fuel consumption.
Lambda sensor process on Jeep Liberty
Before describing you the different problems of lambda probe on Jeep Liberty , we will look a little more in outline at its working to allow you to discover 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 job of managing the amount of oxygen present in the exhaust gases . One could naively presume that this data is measured 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 precise data by compiling the two probes. These data are sent to the ECU which will adapt the quantity of air and gasoline injected into the engine to optimize the combustion .
Lambda sensor issue on Jeep Liberty
.
At last, 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 issue on Jeep Liberty . In a first step we will find out how to identify a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Jeep Liberty is HS
.
It is essential to know that a lambda sensor has generally a lifetime of 150 000 km , this data can differ according to the year of your Jeep Liberty, your driving, and the good performance of your engine. A poorly maintained engine that produces unburned gases may forever alter your lambda sensor. One of the clues that can notify you of a defective lambda sensor on Jeep Liberty may be the engine light comes on, if you want to turn off the engine light of your Jeep Liberty, 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 issue on your Jeep Liberty and to pass your car to the diagnostic case, for that do not think twice to seek advice from our tutorial which explains you Jeep Libertyhow to read the fault code of a Jeep Liberty. Please note that if you have problems with one of your lambda sensors, the just solution to resolve them will be to change the defective sensor.
How to change a lambda sensor on Jeep Liberty?
And finally, we are going to focus on the correction of lambda sensor problems on Jeep Liberty , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite basic to carry out 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 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 necessary to put your Jeep Liberty 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 Jeep Liberty.
