Recent automobiles are progressively built 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 automobiles. This is exactly the subject matter of our content of the day, we are going to look at the complications of the lambda sensor on Dodge Challenger , this sensor also called oxygen sensor plays an essential purpose. To find out, first, we are going to find out what a lambda probe is used for, then, what are the lambda sensor complications on Dodge Challenger and how to fix them.


What is a lambda purpose on Dodge Challenger?

So we begin our content page with the interest of a lambda sensor on Dodge Challenger , we will first see what is the role of this probe and then how it functions.

Role of a lambda sensor on Dodge Challenger

First developed by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on Dodge Challenger , its task is to regulate the amount of oxygen in the exhaust gases, this will enable the engine to modify the air/fuel mixture to decrease the pollution released by the car and reduce the car’s fuel consumption.

Lambda sensor operation on Dodge Challenger

Before explaining you the different complications of lambda probe on Dodge Challenger , we will look a little more in detail at its working to allow you to figure out exactly how it functions and thus to consider more serenely the correction of a problem associated with it.
As we explained to you, a lambda probe has the task of managing the amount of oxygen present in the exhaust gases . One could naively think 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 adjust the quantity of air and gasoline inserted into the engine to optimize the combustion .

Lambda sensor issue on Dodge Challenger

At last, we are now going to attack the section you are absolutely most enthusiastic about this content page, what to do if you have a lambda sensor issue on Dodge Challenger . In a first step we will find out how to locate a lambda sensor HS and in a second step how to change it.

How to know if a lambda sensor on Dodge Challenger is HS

It is essential to know that a lambda sensor has generally a lifetime of 150 000 km , this info can differ according to the year of your Dodge Challenger, your driving, and the good performance of your engine.

One of the clues that can notify you of a faulty lambda sensor on Dodge Challenger may be the engine light comes on, if you want to turn off the engine light of your Dodge Challenger, do not hesitate to visit our dedicated content page to see the procedure to stick to. The only effective way to make sure that you have a lambda sensor issue on your Dodge Challenger and to complete your car to the diagnostic case, for that do not hesitate to seek advice from our tutorial which explains you Dodge Challengerhow to read the fault code of a Dodge Challenger. Please be aware that if you have complications with one of your lambda sensors, the just remedy to resolve them will be to change the faulty sensor.

How to change a lambda sensor on Dodge Challenger?

And finally, we are going to concentrate on the correction of lambda sensor problems on Dodge Challenger , by detailing how to replace a lambda sensor.

The replacement of a lambda sensor is quite basic to carry out and you will be able to do it yourself with a minimal 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 faulty the second one risks to drop you fairly quickly. To replace it, it will be required to put your Dodge Challenger 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 Dodge Challenger.
