Modern vehicles are increasingly pre-loaded 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 released by our vehicles. This is precisely the subject of our article content of the day, we are going to look at the complications of the lambda sensor on Mazda CX 3 , this sensor as well called oxygen sensor plays an essential role. To find out, first, we are going to find out what a lambda probe is utilized for, then, what are the lambda sensor complications on Mazda CX 3 and how to resolve them.

What is a lambda task on Mazda CX 3?

So we begin our article with the benefit of a lambda sensor on Mazda CX 3 , we will first discover what is the job of this probe and then how it functions.

Role of a lambda sensor on Mazda CX 3

First designed by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission standards. As well called oxygen sensor on Mazda CX 3 , its objective is to control the amount of oxygen in the exhaust gases, this will allow the engine to adapt the air/fuel mixture to lower the pollution released by the car and reduce the car’s fuel consumption.

Lambda sensor procedure on Mazda CX 3

Before describing you the different complications of lambda probe on Mazda CX 3 , we will look a little more in outline at its operation to allow you to figure out exactly how it functions 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 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 benefit is to have more precise 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 to improve the combustion .

Lambda sensor issue on Mazda CX 3

.
Finally, we are now going to attack the section you are undoubtedly most enthusiastic about this article, how to handle it if you have a lambda sensor issue on Mazda CX 3 . In a first step we will see how to identify a lambda sensor HS and in a second step how to replace it.

How to know if a lambda sensor on Mazda CX 3 is HS

.
It is essential to know that a lambda sensor has in general a lifetime of 150 000 km , this data can fluctuate according to the year of your Mazda CX 3, your driving, and the good functioning of your engine. A poorly maintained engine that emits unburned gases may permanently corrupt your lambda sensor. One of the clues that can warn you of a faulty lambda sensor on Mazda CX 3 might be the engine light comes on, if you want to turn off the engine light of your Mazda CX 3, do not hesitate to consult our dedicated article to discover the procedure to follow. The only effective method to be certain that you have a lambda sensor issue on your Mazda CX 3 and to complete your car to the diagnostic case, for that do not hesitate to consult our tutorial which explains you Mazda CX 3how to read the fault code of a Mazda CX 3. Take note that if you have complications with one of your lambda sensors, the only remedy to solve them will be to replace the faulty sensor.

How to replace a lambda sensor on Mazda CX 3?

And at last, we are going to focus on the correction of lambda sensor problems on Mazda CX 3 , by describing 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 minimal 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 fairly quickly. To replace it, it will be required to put your Mazda CX 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 CX 3.
