Modern automobiles are more and more furnished with new technologies, apart from the comfort of use it can provide, technology also has the advantage of saving fuel or reducing the pollution emitted 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 Hyundai Sonata , this sensor also called oxygen sensor plays an necessary purpose. To find out, first, we are going to identify what a lambda probe is employed for, then, what are the lambda sensor complications on Hyundai Sonata and how to solve them.

What is a lambda task on Hyundai Sonata?

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

Role of a lambda sensor on Hyundai Sonata

First designed by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission standards. As well called oxygen sensor on Hyundai Sonata , its task is to regulate the amount of oxygen in the exhaust gases, this will allow the engine unit to change the air/fuel mixture to reduce the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.

Lambda sensor process on Hyundai Sonata

Before explaining you the different complications of lambda probe on Hyundai Sonata , we will look a little more in outline at its working to allow you to understand precisely 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 believe that this data is measured 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 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 adapt the quantity of air and gasoline inserted into the engine unit to improve the combustion .

Lambda sensor problem on Hyundai Sonata

.
Finally, we are now going to attack the part you are certainly most interested in this article, how to proceed if you have a lambda sensor problem on Hyundai Sonata . In a first step we will find out how to identify a lambda sensor HS and in a second step how to replace it.

How to know if a lambda sensor on Hyundai Sonata is HS

.
It is necessary to know that a lambda sensor has generally a lifetime of 150 000 km , this data can fluctuate according to the year of your Hyundai Sonata, your driving, and the good performance of your engine unit. A poorly maintained engine unit that produces unburned gases may forever damaged your lambda sensor. One of the clues that can notify you of a faulty lambda sensor on Hyundai Sonata might be the engine unit light turns on, if you want to turn off the engine light of your Hyundai Sonata, do not think twice to visit our dedicated article to see the procedure to stick to. The only effective method to be certain that you have a lambda sensor problem on your Hyundai Sonata and to pass your car to the diagnostic case, for that do not think twice to seek advice from our tutorial which explains you Hyundai Sonatahow to read the fault code of a Hyundai Sonata. Take note that if you have complications with one of your lambda sensors, the just solution to correct them will be to replace the faulty sensor.

How to replace a lambda sensor on Hyundai Sonata?

And finally, we are going to focus on the correction of lambda sensor problems on Hyundai Sonata , by explaining how to replace a lambda sensor.

The replacement of a lambda sensor is quite simple to carry out and you will be able 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 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 Hyundai Sonata 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 Hyundai Sonata.
