Modern cars are progressively equipped 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 cars. This is exactly the subject of our content page of the day, we are going to look at the problems of the lambda sensor on Hyundai Santa Fe , this sensor also known as oxygen sensor plays an important function. To find out, first, we are going to find out what a lambda probe is utilized for, then, what are the lambda sensor problems on Hyundai Santa Fe and how to resolve them.
What is a lambda purpose on Hyundai Santa Fe?
So we begin our article with the benefit of a lambda sensor on Hyundai Santa Fe , we will first discover what is the role of this probe and then how it works.
Role of a lambda sensor on Hyundai Santa Fe
First created by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on Hyundai Santa Fe , its objective is to control the amount of oxygen in the exhaust gases, this will allow the engine unit to adapt the air/fuel mixture to reduce the pollution emitted by the motor vehicle and lower the car’s fuel consumption.

Before explaining you the different problems of lambda probe on Hyundai Santa Fe , we will look a little more in detail at its operation to allow you to figure out exactly how it works and thus to consider more serenely the correction of a problem related to it.
As we explained to you, a lambda probe has the job 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 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 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 .

At last, we are now going to attack the part you are certainly most interested in this article, what to do if you have a lambda sensor problem on Hyundai Santa Fe . In a first step we will discover how to find a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Hyundai Santa Fe is HS
.
It is important to know that a lambda sensor has generally a lifetime of 150 000 km , this info can vary according to the year of your Hyundai Santa Fe, your driving, and the good working of your engine unit. A poorly maintained engine unit that emits unburned gases may forever alter your lambda sensor. One of the clues that can notify you of a faulty lambda sensor on Hyundai Santa Fe might be the engine unit light comes on, if you want to turn off the engine light of your Hyundai Santa Fe, do not think twice to seek advice from our dedicated article to discover the process to stick to. The only effective method to be certain that you have a lambda sensor problem on your Hyundai Santa Fe and to pass your car to the diagnostic case, for that do not think twice to seek advice from our guide which explains you Hyundai Santa Fehow to read the fault code of a Hyundai Santa Fe. Please note that if you have problems 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 Hyundai Santa Fe?
And finally, we are going to focus on the correction of lambda sensor problems on Hyundai Santa Fe , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite simple to carry out 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 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 quickly. To replace it, it will be required to put your Hyundai Santa Fe 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 Santa Fe.
