Modern cars are increasingly pre-loaded 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 cars. This is exactly the subject of our content of the day, we are going to look at the problems of the lambda sensor on Mercedes Benz GLA Class , this sensor also known as oxygen sensor plays an necessary purpose. 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 Mercedes Benz GLA Class and how to solve them.
What is a lambda role on Mercedes Benz GLA Class?
So we start our content page with the benefit of a lambda sensor on Mercedes Benz GLA Class , we will first discover what is the purpose of this probe and then how it works.
Role of a lambda sensor on Mercedes Benz GLA Class
First produced by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission standards. Also called oxygen sensor on Mercedes Benz GLA Class , its task is to control the amount of oxygen in the exhaust gases, this will allow the engine to change the air/fuel mixture to reduce the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.
Lambda sensor operation on Mercedes Benz GLA Class
Before explaining you the different problems of lambda probe on Mercedes Benz GLA Class , we will look a little more in detail at its operation to allow you to understand precisely how it works and thus to consider more serenely the correction of a problem related to it.
As we told you, a lambda probe has the job of managing 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 required before the catalyst, but with the arrival of more drastic standards 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 inserted into the engine to optimize the combustion .
