Latest automobiles are more and more built with new technologies, apart from the comfort of use it can bring, technology as well has the advantage of saving fuel or reducing the pollution emitted by our automobiles. This is exactly the subject matter of our article content of the day, we are going to look at the complications of the lambda sensor on Mazda 3 , this sensor as well called oxygen sensor plays an essential purpose. To find out, first, we are going to identify what a lambda probe is utilized for, then, what are the lambda sensor complications on Mazda 3 and how to fix them.
What is a lambda task on Mazda 3?
So we start our content with the interest of a lambda sensor on Mazda 3 , we will first see what is the task of this probe and then how it works.
Role of a lambda sensor on Mazda 3
First designed 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 Mazda 3 , its goal is to control the amount of oxygen in the exhaust gases, this will allow the engine to change the air/fuel mixture to reduce the pollution emitted by the car and lower the car’s fuel consumption.
Lambda sensor operation on Mazda 3
Before describing you the different complications of lambda probe on Mazda 3 , we will look a little more in detail at its functioning to allow you to discover precisely 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 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 requirements there are now 2 lambda sensors, one before and one after the catalyst . The interest is to have more exact data by compiling the two probes. These data are sent to the ECU which will modify the quantity of air and gasoline inserted into the engine to optimize the combustion .
Lambda sensor issue on Mazda 3
.
Finally, we are now going to attack the part you are certainly most keen on this content, how to handle it if you have a lambda sensor issue on Mazda 3 . 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 Mazda 3 is HS
.
It is essential to know that a lambda sensor has generally a lifetime of 150 000 km , this statistics can differ according to the year of your Mazda 3, your driving, and the good performance of your engine. A poorly taken care of engine that releases unburned gases may completely corrupt your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Mazda 3 might be the engine light turns on, if you want to turn off the engine light of your Mazda 3, do not think twice to visit our dedicated content to see the procedure to follow. The only effective technique to ensure that you have a lambda sensor issue on your Mazda 3 and to complete your car to the diagnostic case, for that do not think twice to consult our tutorial which explains you Mazda 3how to read the fault code of a Mazda 3. Please be aware that if you have complications with one of your lambda sensors, the just remedy to correct them will be to change the faulty sensor.
How to change a lambda sensor on Mazda 3?
And at last, we are going to focus on the correction of lambda sensor problems on Mazda 3 , by detailing how to replace a lambda sensor.
The replacement of a lambda sensor is quite basic to accomplish and you will be able to do it yourself with a minimum 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 faulty the second one risks to drop you quickly. To replace it, it will be necessary to put your Mazda 3 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 Mazda 3.
In the event that you have any additional questions about the Mazda 3, do not hesitate to consult our Mazda 3 category.
