Recent cars are progressively built with new technologies, apart from the comfort of use it can bring, technology as well has the advantage of saving fuel or reducing the pollution emitted by our cars. This is exactly the subject matter of our article of the day, we are going to look at the problems of the lambda sensor on Chevrolet Impala , this sensor as well called oxygen sensor plays an essential purpose. 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 Impala and how to resolve them.
What is a lambda fonction on Chevrolet Impala?
So we start our content page with the benefit of a lambda sensor on Chevrolet Impala , we will first discover what is the task of this probe and then how it functions.
Role of a lambda sensor on Chevrolet Impala
First produced by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on Chevrolet Impala , 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 emitted by the motor vehicle and lower the car’s fuel consumption.

Before describing you the different problems of lambda probe on Chevrolet Impala , we will look a little more in detail at its functioning to allow you to discover precisely how it functions and thus to consider more serenely the correction of a problem associated with it.
As we informed 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 calculated 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 exact 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 .
