Recent cars are more and more equipped 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 precisely the subject of our article content of the day, we are going to look at the complications of the lambda sensor on Volkswagen Routan , this sensor also known as oxygen sensor plays an important function. To find out, first, we are going to identify what a lambda probe is employed for, then, what are the lambda sensor complications on Volkswagen Routan and how to resolve them.

What is a lambda task on Volkswagen Routan?

So we begin our article with the benefit of a lambda sensor on Volkswagen Routan , we will first see what is the function of this probe and then how it works.

Role of a lambda sensor on Volkswagen Routan

First produced by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission specifications. As well called oxygen sensor on Volkswagen Routan , its task is to regulate the amount of oxygen in the exhaust gases, this will allow the engine unit to change the air/fuel mixture to decrease the pollution emitted by the car and reduce the car’s fuel consumption.

Lambda sensor process on Volkswagen Routan

Before describing you the different complications of lambda probe on Volkswagen Routan , we will look a little more in outline at its functioning to allow you to figure out 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 managing the amount of oxygen present in the exhaust gases . One could naively believe 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 needed 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 adapt the quantity of air and gasoline inserted into the engine unit to improve the combustion .

Lambda sensor issue on Volkswagen Routan

.
At last, we are now going to attack the part you are undoubtedly most keen on this article, what to do if you have a lambda sensor issue on Volkswagen Routan . In a first step we will find out how to identify a lambda sensor HS and in a second step how to change it.

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

.
It is important to know that a lambda sensor has generally a lifetime of 150 000 km , this info can vary according to the year of your Volkswagen Routan, your driving, and the good working of your engine unit. A poorly maintained engine unit that releases unburned gases may completely corrupt your lambda sensor. One of the clues that can notify you of a defective lambda sensor on Volkswagen Routan may be the engine unit light comes on, if you want to turn off the engine light of your Volkswagen Routan, do not think twice to seek advice from our dedicated article to see the procedure to follow. The only effective way to ensure that you have a lambda sensor issue on your Volkswagen Routan and to pass your car to the diagnostic case, for that do not think twice to consult our guide which explains you Volkswagen Routanhow to read the fault code of a Volkswagen Routan. Please be aware that if you have complications with one of your lambda sensors, the just solution to correct them will be to change the defective sensor.

How to change a lambda sensor on Volkswagen Routan?

And finally, we are going to concentrate on the correction of lambda sensor problems on Volkswagen Routan , by explaining how to replace a lambda sensor.

The replacement of a lambda sensor is quite simple to carry out and you will be able 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 defective the second one risks to drop you quickly. To replace it, it will be required to put your Volkswagen Routan 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 Routan.
