Latest vehicles are progressively 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 vehicles. 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 Jeep Grand Cherokee , this sensor as well named oxygen sensor plays an important purpose. 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 Grand Cherokee and how to solve them.
What is a lambda purpose on Jeep Grand Cherokee?
So we start our content with the benefit of a lambda sensor on Jeep Grand Cherokee , we will first discover what is the role of this probe and then how it works.
Role of a lambda sensor on Jeep Grand Cherokee
First designed by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on Jeep Grand Cherokee , its goal is to regulate the amount of oxygen in the exhaust gases, this will allow the engine to change the air/fuel mixture to decrease the pollution released by the car and reduce the car’s fuel consumption.
Lambda sensor operation on Jeep Grand Cherokee
Before describing you the different problems of lambda probe on Jeep Grand Cherokee , we will look a little more in detail at its functioning to allow you to understand exactly 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 determined 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 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 benefit 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 inserted into the engine to improve the combustion .

At last, we are now going to attack the section you are absolutely most interested in this content, how to proceed if you have a lambda sensor issue on Jeep Grand Cherokee . In a first step we will see how to find a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Jeep Grand Cherokee is HS

The only effective method to be certain that you have a lambda sensor issue on your Jeep Grand Cherokee and to complete your car to the diagnostic case, for that do not hesitate to consult our tutorial which explains you Jeep Grand Cherokeehow to read the fault code of a Jeep Grand Cherokee. Please note that if you have problems with one of your lambda sensors, the only remedy to resolve them will be to replace the faulty sensor.
How to replace a lambda sensor on Jeep Grand Cherokee?
And at last, we are going to focus on the correction of lambda sensor problems on Jeep Grand Cherokee , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite simple to execute and you will be able to do it yourself with a lowest 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 quickly. To replace it, it will be required to put your Jeep Grand 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 problems with your lambda sensor on Jeep Grand Cherokee.
