Recent automobiles are progressively equipped with new technologies, apart from the comfort of use it can bring, technology also has the advantage of saving fuel or reducing the pollution emitted by our automobiles. This is precisely the subject of our article content of the day, we are going to look at the problems of the lambda sensor on Kia Sedona , this sensor also named oxygen sensor plays an essential 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 Kia Sedona and how to fix them.


What is a lambda role on Kia Sedona?

So we begin our content page with the interest of a lambda sensor on Kia Sedona , we will first discover what is the function of this probe and then how it functions.

Role of a lambda sensor on Kia Sedona

First produced 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 Kia Sedona , its task is to regulate the amount of oxygen in the exhaust gases, this will enable the engine to adapt the air/fuel mixture to reduce the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.

Lambda sensor operation on Kia Sedona

Before describing you the different problems of lambda probe on Kia Sedona , we will look a little more in detail at its working to allow you to discover 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 task of controlling the amount of oxygen present in the exhaust gases . One could naively think 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 only 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 interest is to have more precise data by compiling the two probes. These data are sent to the ECU which will adjust the quantity of air and gasoline injected into the engine to optimize the combustion .

Lambda sensor issue on Kia Sedona

Finally, we are now going to attack the section you are certainly most keen on this content page, what to do if you have a lambda sensor issue on Kia Sedona . In a first step we will find out how to identify a lambda sensor HS and in a second step how to change it.

How to know if a lambda sensor on Kia Sedona is HS

It is essential to know that a lambda sensor has in general a lifetime of 150 000 km , this data can differ according to the year of your Kia Sedona, your driving, and the good functioning of your engine. A poorly looked after engine that produces unburned gases may permanently corrupt your lambda sensor. One of the clues that can notify you of a defective lambda sensor on Kia Sedona might be the engine light turns on, if you want to turn off the engine light of your Kia Sedona, do not think twice to consult our dedicated content page to discover the procedure to follow. The only effective way to be certain that you have a lambda sensor issue on your Kia Sedona and to pass your car to the diagnostic case, for that do not think twice to consult our tutorial which explains you Kia Sedonahow to read the fault code of a Kia Sedona. Please be aware that if you have problems with one of your lambda sensors, the only remedy to solve them will be to change the defective sensor.

How to change a lambda sensor on Kia Sedona?

And at last, we are going to concentrate on the correction of lambda sensor problems on Kia Sedona , by explaining how to replace a lambda sensor.

The replacement of a lambda sensor is quite very easy to accomplish and you will be able to do it yourself with a lowest 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 Kia Sedona 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 Kia Sedona.
