Latest automobiles are more and more 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 automobiles. This is exactly the subject matter of our content page of the day, we are going to look at the problems of the lambda sensor on Chevrolet Avalanche , this sensor as well known as oxygen sensor plays an important purpose. To find out, first, we are going to identify what a lambda probe is employed for, then, what are the lambda sensor problems on Chevrolet Avalanche and how to resolve them.

What is a lambda task on Chevrolet Avalanche?

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

Role of a lambda sensor on Chevrolet Avalanche

First designed by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission specifications. As well called oxygen sensor on Chevrolet Avalanche , its goal is to control the amount of oxygen in the exhaust gases, this will allow the engine unit to adapt the air/fuel mixture to reduce the pollution released by the car and reduce the car’s fuel consumption.

Lambda sensor procedure on Chevrolet Avalanche

Before describing you the different problems of lambda probe on Chevrolet Avalanche , we will look a little more in outline at its functioning to allow you to figure out precisely 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 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 just 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 benefit is to have more precise data by compiling the two probes. These data are sent to the ECU which will adjust the quantity of air and gasoline inserted into the engine unit to optimize the combustion .

Lambda sensor problem on Chevrolet Avalanche

.
At last, we are now going to attack the part you are undoubtedly most enthusiastic about this content page, what to do if you have a lambda sensor problem on Chevrolet Avalanche . In a first step we will find out how to locate a lambda sensor HS and in a second step how to change it.

How to know if a lambda sensor on Chevrolet Avalanche is HS

.
It is important to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this info can differ according to the year of your Chevrolet Avalanche, your driving, and the good working of your engine unit. A poorly taken care of engine unit that emits unburned gases may permanently alter your lambda sensor. One of the clues that can notify you of a defective lambda sensor on Chevrolet Avalanche might be the engine unit light turns on, if you want to turn off the engine light of your Chevrolet Avalanche, do not think twice to consult our dedicated content page to see the procedure to stick to. The only effective technique to be certain that you have a lambda sensor problem on your Chevrolet Avalanche and to pass your car to the diagnostic case, for that do not think twice to seek advice from our guide which explains you Chevrolet Avalanchehow to read the fault code of a Chevrolet Avalanche. Take note that if you have problems with one of your lambda sensors, the just remedy to solve them will be to change the defective sensor.

How to change a lambda sensor on Chevrolet Avalanche?

And at last, we are going to concentrate on the correction of lambda sensor problems on Chevrolet Avalanche , by explaining how to replace a lambda sensor.

The replacement of a lambda sensor is quite simple to carry out 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 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 Chevrolet Avalanche 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 Chevrolet Avalanche.
