Modern vehicles are increasingly furnished 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 released by our vehicles. This is precisely the subject matter of our content page of the day, we are going to look at the problems of the lambda sensor on Volkswagen Golf , this sensor as well named oxygen sensor plays an essential purpose. To find out, first, we are going to identify what a lambda probe is used for, then, what are the lambda sensor problems on Volkswagen Golf and how to resolve them.

What is a lambda task on Volkswagen Golf?

So we begin our content with the interest of a lambda sensor on Volkswagen Golf , we will first discover what is the role of this probe and then how it functions.

Role of a lambda sensor on Volkswagen Golf

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 Volkswagen Golf , its task is to control the amount of oxygen in the exhaust gases, this will enable the engine to change the air/fuel mixture to lower the pollution released by the car and lower the car’s fuel consumption.

Lambda sensor process on Volkswagen Golf

Before describing you the different problems of lambda probe on Volkswagen Golf , we will look a little more in detail at its functioning to allow you to figure out precisely how it functions 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 controlling the amount of oxygen present in the exhaust gases . One could naively believe 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 interest 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 to improve the combustion .

Lambda sensor issue on Volkswagen Golf

.
At last, we are now going to attack the part you are absolutely most keen on this content, how to handle it if you have a lambda sensor issue on Volkswagen Golf . In a first step we will see how to locate a lambda sensor HS and in a second step how to replace it.

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

.
It is essential to know that a lambda sensor has generally a lifetime of 150 000 km , this data can fluctuate according to the year of your Volkswagen Golf, your driving, and the good functioning of your engine. A poorly maintained engine that emits unburned gases may permanently damaged your lambda sensor. One of the clues that can warn you of a faulty lambda sensor on Volkswagen Golf might be the engine light turns on, if you want to turn off the engine light of your Volkswagen Golf, do not think twice to consult our dedicated content to discover the process to stick to. The only effective technique to be certain that you have a lambda sensor issue on your Volkswagen Golf and to complete your car to the diagnostic case, for that do not think twice to consult our tutorial which explains you Volkswagen Golfhow to read the fault code of a Volkswagen Golf. Take note that if you have problems with one of your lambda sensors, the only remedy to resolve them will be to replace the faulty sensor.

How to replace a lambda sensor on Volkswagen Golf?

And at last, we are going to concentrate on the correction of lambda sensor problems on Volkswagen Golf , by detailing how to replace a lambda sensor.

The replacement of a lambda sensor is quite basic to execute and you will be able to do it yourself with a minimal 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 faulty the second one risks to drop you quickly. To replace it, it will be required to put your Volkswagen Golf 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 Golf.
