Latest vehicles are increasingly furnished with new technologies, apart from the comfort of use it can bring, technology also has the advantage of saving fuel or reducing the pollution released by our vehicles. This is exactly the subject of our content page of the day, we are going to look at the problems of the lambda sensor on Volkswagen Tiguan , this sensor also known as oxygen sensor plays an necessary role. To find out, first, we are going to find out what a lambda probe is employed for, then, what are the lambda sensor problems on Volkswagen Tiguan and how to fix them.

What is a lambda fonction on Volkswagen Tiguan?

So we start our content with the benefit of a lambda sensor on Volkswagen Tiguan , we will first see what is the role of this probe and then how it functions.

Role of a lambda sensor on Volkswagen Tiguan

First designed 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 Volkswagen Tiguan , its task is to control the amount of oxygen in the exhaust gases, this will enable the engine unit to adapt the air/fuel mixture to decrease the pollution released by the motor vehicle and reduce the car’s fuel consumption.

Lambda sensor process on Volkswagen Tiguan

Before explaining you the different problems of lambda probe on Volkswagen Tiguan , we will look a little more in outline at its operation to allow you to understand precisely 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 controlling 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 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 injected into the engine unit to optimize the combustion .

Lambda sensor problem on Volkswagen Tiguan

.
At last, we are now going to attack the part you are undoubtedly most interested in this content, what to do if you have a lambda sensor problem on Volkswagen Tiguan . In a first step we will discover how to locate a lambda sensor HS and in a second step how to change it.

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

.
It is necessary 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 Volkswagen Tiguan, your driving, and the good functioning of your engine unit. A poorly maintained engine unit that emits unburned gases may forever corrupt your lambda sensor. One of the clues that can warn you of a defective lambda sensor on Volkswagen Tiguan may be the engine unit light turns on, if you want to turn off the engine light of your Volkswagen Tiguan, do not hesitate to consult our dedicated content to see the process to stick to. The only effective technique to ensure that you have a lambda sensor problem on your Volkswagen Tiguan and to pass your car to the diagnostic case, for that do not hesitate to seek advice from our tutorial which explains you Volkswagen Tiguanhow to read the fault code of a Volkswagen Tiguan. Take note that if you have problems with one of your lambda sensors, the only remedy to resolve them will be to change the defective sensor.

How to change a lambda sensor on Volkswagen Tiguan?

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

The replacement of a lambda sensor is quite basic to accomplish and you will have the ability to do it yourself with a minimum of tools and mechanical know-how. 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 necessary to put your Volkswagen Tiguan 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 Volkswagen Tiguan.
