Latest vehicles are increasingly furnished 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 vehicles. This is precisely the subject of our content of the day, we are going to look at the problems of the lambda sensor on Chevrolet Volt , this sensor also known as oxygen sensor plays an important function. To find out, first, we are going to find out what a lambda probe is used for, then, what are the lambda sensor problems on Chevrolet Volt and how to fix them.
What is a lambda purpose on Chevrolet Volt?
So we begin our content page with the benefit of a lambda sensor on Chevrolet Volt , we will first discover what is the purpose of this probe and then how it functions.
Role of a lambda sensor on Chevrolet Volt
First produced by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on Chevrolet Volt , its goal is to control the amount of oxygen in the exhaust gases, this will enable the engine to change the air/fuel mixture to decrease the pollution emitted by the car and lower the car’s fuel consumption.
Lambda sensor process on Chevrolet Volt
Before describing you the different problems of lambda probe on Chevrolet Volt , we will look a little more in detail at its working to allow you to figure out exactly how it functions and thus to consider more serenely the correction of a problem related to it.
As we told you, a lambda probe has the task of controlling the amount of oxygen present in the exhaust gases . One could naively think 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 just one lambda sensor needed 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 benefit 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 injected into the engine to optimize the combustion .
Lambda sensor problem on Chevrolet Volt
.
Finally, we are now going to attack the section you are obviously most interested in this content page, what to do if you have a lambda sensor problem on Chevrolet Volt . In a first step we will discover how to locate a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Chevrolet Volt is HS
.
It is important to know that a lambda sensor has in general a lifetime of 150 000 km , this data can fluctuate according to the year of your Chevrolet Volt, your driving, and the good functioning of your engine. A poorly looked after engine that produces unburned gases may forever alter your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Chevrolet Volt might be the engine light comes on, if you want to turn off the engine light of your Chevrolet Volt, do not hesitate to seek advice from our dedicated content page to discover the process to stick to. The only effective method to be sure that you have a lambda sensor problem on your Chevrolet Volt and to complete your car to the diagnostic case, for that do not hesitate to seek advice from our guide which explains you Chevrolet Volthow to read the fault code of a Chevrolet Volt. Please note that if you have problems with one of your lambda sensors, the just solution to correct them will be to replace the faulty sensor.
How to replace a lambda sensor on Chevrolet Volt?
And at last, we are going to concentrate on the correction of lambda sensor problems on Chevrolet Volt , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite basic to perform and you will be able 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 faulty the second one risks to drop you fairly quickly. To replace it, it will be necessary to put your Chevrolet Volt 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 Volt.
