Latest automobiles are progressively pre-loaded with new technologies, apart from the comfort of use it can provide, technology also has the advantage of saving fuel or reducing the pollution released by our automobiles. 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 Hyundai Accent , this sensor also called oxygen sensor plays an important purpose. To find out, first, we are going to find out what a lambda probe is employed for, then, what are the lambda sensor problems on Hyundai Accent and how to solve them.


What is a lambda fonction on Hyundai Accent?

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

Role of a lambda sensor on Hyundai Accent

First developed by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission standards. Also called oxygen sensor on Hyundai Accent , its objective is to regulate the amount of oxygen in the exhaust gases, this will enable the engine unit to adapt the air/fuel mixture to lower the pollution released by the car and reduce the car’s fuel consumption.

Lambda sensor operation on Hyundai Accent

Before explaining you the different problems of lambda probe on Hyundai Accent , we will look a little more in detail at its operation to allow you to understand exactly how it functions and thus to consider more serenely the correction of a problem related to it.
As we informed you, a lambda probe has the job of controlling 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 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 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 unit to improve the combustion .

Lambda sensor issue on Hyundai Accent

Finally, we are now going to attack the part you are absolutely most interested in this article, what to do if you have a lambda sensor issue on Hyundai Accent . 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 Hyundai Accent is HS

It is important to know that a lambda sensor has generally a lifetime of 150 000 km , this statistics can differ according to the year of your Hyundai Accent, your driving, and the good working of your engine unit. A poorly looked after engine unit that releases unburned gases may forever alter your lambda sensor. One of the clues that can warn you of a defective lambda sensor on Hyundai Accent may be the engine unit light comes on, if you want to turn off the engine light of your Hyundai Accent, do not think twice to seek advice from our dedicated article to see the process to follow. The only effective way to be certain that you have a lambda sensor issue on your Hyundai Accent and to complete your car to the diagnostic case, for that do not think twice to seek advice from our guide which explains you Hyundai Accenthow to read the fault code of a Hyundai Accent. Please note that if you have problems with one of your lambda sensors, the just solution to solve them will be to change the defective sensor.

How to change a lambda sensor on Hyundai Accent?

And finally, we are going to concentrate on the correction of lambda sensor problems on Hyundai Accent , by describing how to replace a lambda sensor.

The replacement of a lambda sensor is quite simple to perform and you will have the ability to do it yourself with a minimum 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 necessary to put your Hyundai Accent 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 Hyundai Accent.
