Recent automobiles are increasingly 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 precisely the subject matter of our article content of the day, we are going to look at the problems of the lambda sensor on Hyundai Elantra , this sensor as well called oxygen sensor plays an essential 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 Hyundai Elantra and how to fix them.

What is a lambda task on Hyundai Elantra?

So we start our content page with the benefit of a lambda sensor on Hyundai Elantra , we will first discover what is the role of this probe and then how it works.

Role of a lambda sensor on Hyundai Elantra

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 Hyundai Elantra , its objective 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 emitted by the motor vehicle and lower the car’s fuel consumption.

Lambda sensor process on Hyundai Elantra

Before describing you the different problems of lambda probe on Hyundai Elantra , we will look a little more in detail at its working 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 managing 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 needed 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 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 .

How to replace a lambda sensor on Hyundai Elantra?

And at last, we are going to concentrate on the correction of lambda sensor problems on Hyundai Elantra , by detailing how to replace a lambda sensor.

The replacement of a lambda sensor is quite basic to accomplish and you will have the ability to do it yourself with a minimal of tools and mechanical knowledge. 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 necessary to put your Hyundai Elantra on candles and at the level of your catalyst unscrew your probes, disconnect them, reconnect them and screw the new ones .
