Modern vehicles are progressively built with new technologies, apart from the comfort of use it can bring, technology as well has the advantage of saving fuel or reducing the pollution emitted by our vehicles. This is exactly the subject matter of our article of the day, we are going to look at the problems of the lambda sensor on Volkswagen Beetle , this sensor as well known as oxygen sensor plays an necessary function. 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 Beetle and how to fix them.
What is a lambda task on Volkswagen Beetle?
So we begin our content page with the interest of a lambda sensor on Volkswagen Beetle , we will first discover what is the task of this probe and then how it works.
Role of a lambda sensor on Volkswagen Beetle
First developed by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission specifications. As well called oxygen sensor on Volkswagen Beetle , 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 reduce the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.
Lambda sensor operation on Volkswagen Beetle
Before explaining you the different problems of lambda probe on Volkswagen Beetle , we will look a little more in detail at its functioning to allow you to understand 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 task 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 specifications 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 adapt the quantity of air and gasoline inserted into the engine unit to optimize the combustion .
Lambda sensor problem on Volkswagen Beetle
.
At last, we are now going to attack the part you are absolutely most interested in this content page, what to do if you have a lambda sensor problem on Volkswagen Beetle . In a first step we will find out how to find a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Volkswagen Beetle is HS
.
It is necessary to know that a lambda sensor has in general a lifetime of 150 000 km , this statistics can vary according to the year of your Volkswagen Beetle, your driving, and the good functioning 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 warn you of a defective lambda sensor on Volkswagen Beetle may be the engine unit light comes on, if you want to turn off the engine light of your Volkswagen Beetle, do not hesitate to consult our dedicated content page to discover the process to stick to. The only effective technique to ensure that you have a lambda sensor problem on your Volkswagen Beetle and to complete your car to the diagnostic case, for that do not hesitate to seek advice from our tutorial which explains you Volkswagen Beetlehow to read the fault code of a Volkswagen Beetle. Take note that if you have problems with one of your lambda sensors, the only remedy to correct them will be to replace the defective sensor.
How to replace a lambda sensor on Volkswagen Beetle?
And at last, we are going to focus on the correction of lambda sensor problems on Volkswagen Beetle , by describing how to replace a lambda sensor.
The replacement of a lambda sensor is quite very easy to perform and you will have the ability 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 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 quickly. To replace it, it will be required to put your Volkswagen Beetle 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 Beetle.
