Latest cars are progressively 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 cars. This is exactly the subject of our content of the day, we are going to look at the complications of the lambda sensor on Porsche Cayenne , this sensor also known as 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 Porsche Cayenne and how to fix them.
What is a lambda task on Porsche Cayenne?
So we start our content with the benefit of a lambda sensor on Porsche Cayenne , we will first discover what is the role of this probe and then how it works.
Role of a lambda sensor on Porsche Cayenne
First created by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on Porsche Cayenne , its mission is to regulate the amount of oxygen in the exhaust gases, this will allow the engine unit to change the air/fuel mixture to reduce the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.
Lambda sensor operation on Porsche Cayenne
Before explaining you the different complications of lambda probe on Porsche Cayenne , we will look a little more in detail at its operation to allow you to understand exactly how it works and thus to consider more serenely the correction of a problem related to it.
As we informed you, a lambda probe has the task 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 only 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 benefit is to have more precise 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 unit to optimize the combustion .

Finally, we are now going to attack the section you are absolutely most enthusiastic about this content, how to proceed if you have a lambda sensor problem on Porsche Cayenne . 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 Porsche Cayenne is HS
.
It is essential to know that a lambda sensor has in general a lifetime of 150 000 km , this data can differ according to the year of your Porsche Cayenne, your driving, and the good working of your engine unit. A poorly looked after engine unit that produces unburned gases may forever corrupt your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Porsche Cayenne may be the engine unit light turns on, if you want to turn off the engine light of your Porsche Cayenne, do not think twice to consult our dedicated content to discover the procedure to stick to. The only effective way to make sure that you have a lambda sensor problem on your Porsche Cayenne and to complete your car to the diagnostic case, for that do not think twice to consult our tutorial which explains you Porsche Cayennehow to read the fault code of a Porsche Cayenne. Please note that if you have complications with one of your lambda sensors, the only solution to resolve them will be to change the faulty sensor.
How to change a lambda sensor on Porsche Cayenne?
And finally, we are going to focus on the correction of lambda sensor problems on Porsche Cayenne , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite very easy to perform and you will be able 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 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 fairly quickly. To replace it, it will be necessary to put your Porsche Cayenne 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 Porsche Cayenne.
