Latest automobiles are more and more furnished with new technologies, apart from the comfort of use it can provide, technology also has the advantage of saving fuel or reducing the pollution emitted by our automobiles. 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 Express , this sensor also named oxygen sensor plays an important function. To find out, first, we are going to find out what a lambda probe is utilized for, then, what are the lambda sensor problems on Chevrolet Express and how to resolve them.
What is a lambda task on Chevrolet Express?
So we begin our content page with the benefit of a lambda sensor on Chevrolet Express , we will first discover what is the task of this probe and then how it functions.
Role of a lambda sensor on Chevrolet Express
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 Chevrolet Express , its goal is to regulate the amount of oxygen in the exhaust gases, this will allow the engine to modify the air/fuel mixture to decrease the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.

Before explaining you the different problems of lambda probe on Chevrolet Express , we will look a little more in outline at its functioning 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 informed 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 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 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 exact data by compiling the two probes. These data are sent to the ECU which will modify the quantity of air and gasoline inserted into the engine to optimize the combustion .
