Latest automobiles are increasingly built 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 automobiles. This is precisely the subject of our article of the day, we are going to look at the problems of the lambda sensor on Porsche Macan , this sensor also known as oxygen sensor plays an necessary purpose. To find out, first, we are going to find out what a lambda probe is used for, then, what are the lambda sensor problems on Porsche Macan and how to solve them.
What is a lambda purpose on Porsche Macan?
So we start our content with the benefit of a lambda sensor on Porsche Macan , we will first see what is the purpose of this probe and then how it functions.
Role of a lambda sensor on Porsche Macan
First produced by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission specifications. As well called oxygen sensor on Porsche Macan , its task is to control the amount of oxygen in the exhaust gases, this will enable the engine to adapt the air/fuel mixture to lower the pollution emitted by the motor vehicle and lower the car’s fuel consumption.
Lambda sensor procedure on Porsche Macan
Before describing you the different problems of lambda probe on Porsche Macan , we will look a little more in detail at its functioning to allow you to discover precisely how it functions and thus to consider more serenely the correction of a problem related to 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 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 injected into the engine to optimize the combustion .
Lambda sensor issue on Porsche Macan
.
Finally, we are now going to attack the part you are obviously most enthusiastic about this content, what to do if you have a lambda sensor issue on Porsche Macan . In a first step we will find out how to find a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Porsche Macan is HS
.
It is necessary to know that a lambda sensor has generally a lifetime of 150 000 km , this info can differ according to the year of your Porsche Macan, your driving, and the good working of your engine. A poorly taken care of engine that releases unburned gases may forever alter your lambda sensor. One of the clues that can warn you of a faulty lambda sensor on Porsche Macan might be the engine light comes on, if you want to turn off the engine light of your Porsche Macan, do not hesitate to consult our dedicated content to see the procedure to follow. The only effective way to be sure that you have a lambda sensor issue on your Porsche Macan and to complete your car to the diagnostic case, for that do not hesitate to seek advice from our tutorial which explains you Porsche Macanhow to read the fault code of a Porsche Macan. Take note that if you have problems with one of your lambda sensors, the just solution to correct them will be to change the faulty sensor.
How to change a lambda sensor on Porsche Macan?
And at last, we are going to focus on the correction of lambda sensor problems on Porsche Macan , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite very easy to accomplish and you will have the ability to do it yourself with a lowest 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 necessary to put your Porsche Macan 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 Porsche Macan.
In the event that you have any further questions about the Porsche Macan, do not hesitate to consult our Porsche Macan category.
