Modern automobiles are more and more pre-loaded 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 emitted by our automobiles. This is exactly the subject matter of our article content of the day, we are going to look at the problems of the lambda sensor on Vauxkhall Astra , this sensor as well named oxygen sensor plays an necessary 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 Vauxkhall Astra and how to resolve them.

What is a lambda task on Vauxkhall Astra?

So we begin our content page with the benefit of a lambda sensor on Vauxkhall Astra , we will first see what is the job of this probe and then how it works.

Role of a lambda sensor on Vauxkhall Astra

First created by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission specifications. Also called oxygen sensor on Vauxkhall Astra , 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 reduce the pollution emitted by the car and lower the car’s fuel consumption.

Lambda sensor process on Vauxkhall Astra

Before explaining you the different problems of lambda probe on Vauxkhall Astra , we will look a little more in outline at its working to allow you to figure out exactly how it works and thus to consider more serenely the correction of a problem associated with 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 determined 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 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 improve the combustion .

Lambda sensor issue on Vauxkhall Astra

.
At last, we are now going to attack the part you are undoubtedly most keen on this content page, how to handle it if you have a lambda sensor issue on Vauxkhall Astra . 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 Vauxkhall Astra is HS

.
It is necessary to know that a lambda sensor has generally a lifetime of 150 000 km , this statistics can vary according to the year of your Vauxkhall Astra, your driving, and the good working of your engine unit. A poorly taken care of engine unit that releases unburned gases may permanently damaged your lambda sensor. One of the clues that can warn you of a defective lambda sensor on Vauxkhall Astra might be the engine unit light turns on, if you want to turn off the engine light of your Vauxkhall Astra, do not think twice to visit our dedicated content page to see the process to stick to. The only effective technique to ensure that you have a lambda sensor issue on your Vauxkhall Astra and to pass your car to the diagnostic case, for that do not think twice to seek advice from our guide which explains you Vauxkhall Astrahow to read the fault code of a Vauxkhall Astra. Please be aware that if you have problems with one of your lambda sensors, the just remedy to correct them will be to replace the defective sensor.

How to replace a lambda sensor on Vauxkhall Astra?

And finally, we are going to focus on the correction of lambda sensor problems on Vauxkhall Astra , by detailing how to replace a lambda sensor.

The replacement of a lambda sensor is quite basic to accomplish 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 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 Vauxkhall Astra 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 Vauxkhall Astra.
