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 emitted by our cars. This is precisely the subject matter of our content page of the day, we are going to look at the complications of the lambda sensor on Jeep Cherokee , this sensor as well called oxygen sensor plays an important function. To find out, first, we are going to identify what a lambda probe is utilized for, then, what are the lambda sensor complications on Jeep Cherokee and how to fix them.
What is a lambda fonction on Jeep Cherokee?
So we start our content with the interest of a lambda sensor on Jeep Cherokee , we will first discover what is the purpose of this probe and then how it works.
Role of a lambda sensor on Jeep Cherokee
First developed 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 Jeep Cherokee , its objective 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 car and reduce the car’s fuel consumption.
Lambda sensor process on Jeep Cherokee
Before describing you the different complications of lambda probe on Jeep Cherokee , we will look a little more in outline at its working to allow you to discover precisely how it works and thus to consider more serenely the correction of a problem associated with 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 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 only 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 interest 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 problem on Jeep Cherokee
.
At last, we are now going to attack the part you are obviously most interested in this content, how to proceed if you have a lambda sensor problem on Jeep Cherokee . In a first step we will discover 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 Cherokee 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 Jeep Cherokee, your driving, and the good performance of your engine. A poorly taken care of engine that releases unburned gases may forever damaged your lambda sensor. One of the clues that can notify you of a defective lambda sensor on Jeep Cherokee might be the engine light comes on, if you want to turn off the engine light of your Jeep Cherokee, do not think twice to visit our dedicated content to discover the process to stick to. The only effective way to be sure that you have a lambda sensor problem on your Jeep Cherokee and to complete your car to the diagnostic case, for that do not think twice to consult our tutorial which explains you Jeep Cherokeehow to read the fault code of a Jeep Cherokee. Please note that if you have complications with one of your lambda sensors, the only remedy to solve them will be to change the defective sensor.
How to change a lambda sensor on Jeep Cherokee?
And at last, we are going to focus on the correction of lambda sensor problems on Jeep Cherokee , by detailing how to replace a lambda sensor.
The replacement of a lambda sensor is quite simple to accomplish and you will have the ability 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 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 Jeep Cherokee 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 Jeep Cherokee.
