Modern cars are progressively pre-loaded with new technologies, apart from the comfort of use it can bring, technology also has the advantage of saving fuel or reducing the pollution emitted by our cars. This is precisely the subject of our article of the day, we are going to look at the complications of the lambda sensor on Volkswagen Rabbit , this sensor also called 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 complications on Volkswagen Rabbit and how to resolve them.
What is a lambda fonction on Volkswagen Rabbit?
So we start our article with the interest of a lambda sensor on Volkswagen Rabbit , we will first see what is the role of this probe and then how it functions.
Role of a lambda sensor on Volkswagen Rabbit
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 Rabbit , its task is to regulate the amount of oxygen in the exhaust gases, this will enable the engine unit to modify the air/fuel mixture to lower the pollution emitted by the car and reduce the car’s fuel consumption.
Lambda sensor process on Volkswagen Rabbit
Before explaining you the different complications of lambda probe on Volkswagen Rabbit , we will look a little more in outline at its operation to allow you to discover precisely how it functions 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 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 only 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 interest is to have more exact data by compiling the two probes. These data are sent to the ECU which will adjust the quantity of air and gasoline injected into the engine unit to optimize the combustion .
Lambda sensor problem on Volkswagen Rabbit
.
Finally, we are now going to attack the section you are obviously most enthusiastic about this article, how to proceed if you have a lambda sensor problem on Volkswagen Rabbit . In a first step we will discover how to find a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Volkswagen Rabbit is HS
.
It is necessary to know that a lambda sensor has in general a lifetime of 150 000 km , this info can vary according to the year of your Volkswagen Rabbit, your driving, and the good functioning of your engine unit. A poorly looked after engine unit that emits unburned gases may completely damaged your lambda sensor. One of the clues that can alert you of a defective lambda sensor on Volkswagen Rabbit might be the engine unit light comes on, if you want to turn off the engine light of your Volkswagen Rabbit, do not think twice to consult our dedicated article to see the procedure to stick to. The only effective method to be certain that you have a lambda sensor problem on your Volkswagen Rabbit and to complete your car to the diagnostic case, for that do not think twice to seek advice from our guide which explains you Volkswagen Rabbithow to read the fault code of a Volkswagen Rabbit. Take note that if you have complications with one of your lambda sensors, the only solution to correct them will be to change the defective sensor.
How to change a lambda sensor on Volkswagen Rabbit?
And at last, we are going to concentrate on the correction of lambda sensor problems on Volkswagen Rabbit , by describing how to replace a lambda sensor.
The replacement of a lambda sensor is quite very easy to accomplish and you will be able to do it yourself with a lowest 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 Rabbit 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 Rabbit.
