Latest vehicles are more and more pre-loaded 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 vehicles. 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 City Express , this sensor as well known as oxygen sensor plays an important function. To find out, first, we are going to identify what a lambda probe is utilized for, then, what are the lambda sensor problems on Chevrolet City Express and how to resolve them.
What is a lambda task on Chevrolet City Express?
So we start our content page with the benefit of a lambda sensor on Chevrolet City Express , we will first discover what is the task of this probe and then how it works.
Role of a lambda sensor on Chevrolet City Express
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 City Express , its goal is to regulate the amount of oxygen in the exhaust gases, this will allow the engine unit to modify the air/fuel mixture to lower the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.

One could naively presume 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 only one lambda sensor required 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 modify the quantity of air and gasoline inserted into the engine unit to improve the combustion .
