Recent cars are progressively 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 released by our cars. This is exactly the subject of our content page of the day, we are going to look at the problems of the lambda sensor on Chevrolet Malibu , this sensor also called 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 Malibu and how to resolve them.
What is a lambda task on Chevrolet Malibu?
So we begin our content with the interest of a lambda sensor on Chevrolet Malibu , we will first see what is the task of this probe and then how it functions.
Role of a lambda sensor on Chevrolet Malibu
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 Malibu , its task is to regulate the amount of oxygen in the exhaust gases, this will allow the engine unit to modify the air/fuel mixture to decrease the pollution released by the motor vehicle and lower the car’s fuel consumption.
Lambda sensor procedure on Chevrolet Malibu
Before describing you the different problems of lambda probe on Chevrolet Malibu , we will look a little more in detail at its working to allow you to understand precisely how it functions and thus to consider more serenely the correction of a problem related to it.
As we explained to you, a lambda probe has the job of managing the amount of oxygen present in the exhaust gases . One could naively presume 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 interest is to have more exact data by compiling the two probes. These data are sent to the ECU which will adjust the quantity of air and gasoline inserted into the engine unit to improve the combustion .

Please note that if you have problems with one of your lambda sensors, the just remedy to solve them will be to replace the faulty sensor.
How to replace a lambda sensor on Chevrolet Malibu?
And finally, we are going to focus on the correction of lambda sensor problems on Chevrolet Malibu , by describing how to replace a lambda sensor.
The replacement of a lambda sensor is quite simple to perform and you will be able to do it yourself with a minimum of tools and mechanical knowledge. A lambda sensor is worth between 25 and 50€ , it is better to replace the 2 lambda sensors present upstream and downstream of your catalytic converter because if one of them is faulty the second one risks to drop you fairly quickly. To replace it, it will be required to put your Chevrolet Malibu on candles and at the level of your catalyst unscrew your probes, disconnect them, reconnect them and screw the new ones .
