Latest automobiles are increasingly 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 exactly the subject matter of our article of the day, we are going to look at the complications of the lambda sensor on Chevrolet Tahoe , this sensor also named oxygen sensor plays an essential function. To find out, first, we are going to find out what a lambda probe is utilized for, then, what are the lambda sensor complications on Chevrolet Tahoe and how to fix them.


What is a lambda purpose on Chevrolet Tahoe?

So we start our content with the interest of a lambda sensor on Chevrolet Tahoe , we will first discover what is the role of this probe and then how it works.

Role of a lambda sensor on Chevrolet Tahoe

First created 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 Tahoe , its goal is to control the amount of oxygen in the exhaust gases, this will enable the engine unit to change the air/fuel mixture to decrease the pollution emitted by the car and reduce the car’s fuel consumption.

Before explaining you the different complications of lambda probe on Chevrolet Tahoe , we will look a little more in outline at its working to allow you to understand precisely how it works 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 think 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 needed 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 interest 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 unit to optimize the combustion .
