Recent automobiles are progressively pre-loaded 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 exactly the subject of our content of the day, we are going to look at the problems of the lambda sensor on Jeep Wrangler , this sensor as well called oxygen sensor plays an necessary role. 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 Wrangler and how to solve them.

What is a lambda role on Jeep Wrangler?

So we begin our article with the benefit of a lambda sensor on Jeep Wrangler , we will first see what is the function of this probe and then how it functions.

Role of a lambda sensor on Jeep Wrangler

First designed by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission specifications. As well called oxygen sensor on Jeep Wrangler , its goal is to regulate the amount of oxygen in the exhaust gases, this will enable the engine unit to change the air/fuel mixture to lower the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.

Lambda sensor operation on Jeep Wrangler

Before describing you the different problems of lambda probe on Jeep Wrangler , we will look a little more in detail at its working to allow you to understand exactly how it functions and thus to consider more serenely the correction of a problem associated with it.
As we told you, a lambda probe has the job of controlling the amount of oxygen present in the exhaust gases . One could naively presume 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 required before the catalyst, but with the arrival of more drastic specifications 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 unit to optimize the combustion .

Lambda sensor issue on Jeep Wrangler

.
Finally, we are now going to attack the section you are absolutely most enthusiastic about this article, how to proceed if you have a lambda sensor issue on Jeep Wrangler . In a first step we will discover how to locate a lambda sensor HS and in a second step how to change it.

How to know if a lambda sensor on Jeep Wrangler is HS

.
It is necessary to know that a lambda sensor has in general a lifetime of 150 000 km , this data can vary according to the year of your Jeep Wrangler, your driving, and the good performance of your engine unit. A poorly maintained engine unit that emits unburned gases may forever alter your lambda sensor. One of the clues that can notify you of a faulty lambda sensor on Jeep Wrangler might be the engine unit light comes on, if you want to turn off the engine light of your Jeep Wrangler, do not think twice to visit 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 Wrangler 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 Wranglerhow to read the fault code of a Jeep Wrangler. Please note that if you have problems with one of your lambda sensors, the only solution to solve them will be to change the faulty sensor.

How to change a lambda sensor on Jeep Wrangler?

And finally, we are going to focus on the correction of lambda sensor problems on Jeep Wrangler , by detailing how to replace a lambda sensor.

The replacement of a lambda sensor is quite simple to carry out and you will have the ability to do it yourself with a minimum 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 faulty the second one risks to drop you fairly quickly. To replace it, it will be required to put your Jeep Wrangler 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 Wrangler.
