Modern automobiles are increasingly furnished with new technologies, apart from the comfort of use it can provide, technology as well has the advantage of saving fuel or reducing the pollution released by our automobiles. This is exactly the subject matter of our article content of the day, we are going to look at the problems of the lambda sensor on Mazda 6 , this sensor as well called oxygen sensor plays an essential function. 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 Mazda 6 and how to fix them.
What is a lambda task on Mazda 6?
So we begin our content with the benefit of a lambda sensor on Mazda 6 , we will first discover what is the task of this probe and then how it works.
Role of a lambda sensor on Mazda 6
First developed 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 Mazda 6 , its goal is to regulate the amount of oxygen in the exhaust gases, this will allow the engine to adapt the air/fuel mixture to decrease the pollution released by the car and lower the car’s fuel consumption.
Lambda sensor procedure on Mazda 6
Before describing you the different problems of lambda probe on Mazda 6 , we will look a little more in outline at its functioning to allow you to figure out exactly how it works and thus to consider more serenely the correction of a problem associated with it.
As we informed you, a lambda probe has the task of controlling the amount of oxygen present in the exhaust gases . One could naively believe 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 required 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 improve the combustion .
Lambda sensor issue on Mazda 6
.
At last, we are now going to attack the section you are certainly most enthusiastic about this content, what to do if you have a lambda sensor issue on Mazda 6 . In a first step we will see how to locate a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Mazda 6 is HS
.
It is essential to know that a lambda sensor has in general a lifetime of 150 000 km , this info can differ according to the year of your Mazda 6, your driving, and the good working of your engine. A poorly maintained engine that produces unburned gases may permanently corrupt your lambda sensor. One of the clues that can warn you of a defective lambda sensor on Mazda 6 might be the engine light comes on, if you want to turn off the engine light of your Mazda 6, do not think twice to seek advice from our dedicated content to discover the procedure to follow. The only effective method to make sure that you have a lambda sensor issue on your Mazda 6 and to pass your car to the diagnostic case, for that do not think twice to seek advice from our guide which explains you Mazda 6how to read the fault code of a Mazda 6. Please be aware that if you have problems with one of your lambda sensors, the just remedy to resolve them will be to change the defective sensor.
How to change a lambda sensor on Mazda 6?
And finally, we are going to concentrate on the correction of lambda sensor problems on Mazda 6 , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite basic to execute and you will have the ability to do it yourself with a lowest of tools and mechanical know-how. 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 Mazda 6 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 Mazda 6.
