Latest automobiles are progressively equipped 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 emitted by our automobiles. This is exactly the subject of our content of the day, we are going to look at the complications of the lambda sensor on Volkswagen CC , this sensor as well called oxygen sensor plays an important function. To find out, first, we are going to identify what a lambda probe is used for, then, what are the lambda sensor complications on Volkswagen CC and how to solve them.

What is a lambda purpose on Volkswagen CC?

So we start our content page with the interest of a lambda sensor on Volkswagen CC , we will first see what is the purpose of this probe and then how it works.

Role of a lambda sensor on Volkswagen CC

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. Also called oxygen sensor on Volkswagen CC , its mission is to control the amount of oxygen in the exhaust gases, this will allow the engine unit to modify the air/fuel mixture to reduce the pollution emitted by the car and reduce the car’s fuel consumption.

Lambda sensor procedure on Volkswagen CC

Before describing you the different complications of lambda probe on Volkswagen CC , we will look a little more in detail at its working to allow you to discover precisely 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 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 only one lambda sensor required 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 interest is to have more exact 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 unit to improve the combustion .

Lambda sensor problem on Volkswagen CC

.
At last, we are now going to attack the section you are certainly most keen on this content page, what to do if you have a lambda sensor problem on Volkswagen CC . In a first step we will find out how to identify a lambda sensor HS and in a second step how to replace it.

How to know if a lambda sensor on Volkswagen CC is HS

.
It is important to know that a lambda sensor has generally a lifetime of 150 000 km , this data can vary according to the year of your Volkswagen CC, your driving, and the good working of your engine unit. A poorly maintained engine unit that produces unburned gases may permanently corrupt your lambda sensor. One of the clues that can warn you of a defective lambda sensor on Volkswagen CC may be the engine unit light turns on, if you want to turn off the engine light of your Volkswagen CC, do not think twice to consult our dedicated content page to see the process to follow. The only effective method to ensure that you have a lambda sensor problem on your Volkswagen CC and to pass your car to the diagnostic case, for that do not think twice to consult our tutorial which explains you Volkswagen CChow to read the fault code of a Volkswagen CC. Take note that if you have complications with one of your lambda sensors, the only solution to resolve them will be to replace the defective sensor.

How to replace a lambda sensor on Volkswagen CC?

And at last, we are going to focus on the correction of lambda sensor problems on Volkswagen CC , by describing how to replace a lambda sensor.

The replacement of a lambda sensor is quite simple to perform and you will be able to do it yourself with a minimum of tools and mechanical knowledge. 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 defective the second one risks to drop you fairly quickly. To replace it, it will be required to put your Volkswagen CC 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 Volkswagen CC.
