Latest 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 released by our cars. This is precisely the subject of our article of the day, we are going to look at the problems of the lambda sensor on Chevrolet Sonic , this sensor also named oxygen sensor plays an necessary 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 Sonic and how to fix them.
What is a lambda task on Chevrolet Sonic?
So we begin our content with the interest of a lambda sensor on Chevrolet Sonic , we will first discover what is the purpose of this probe and then how it works.
Role of a lambda sensor on Chevrolet Sonic
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. As well called oxygen sensor on Chevrolet Sonic , its mission is to regulate the amount of oxygen in the exhaust gases, this will enable the engine unit to adapt the air/fuel mixture to decrease the pollution released by the car and reduce the car’s fuel consumption.
Lambda sensor process on Chevrolet Sonic
Before describing you the different problems of lambda probe on Chevrolet Sonic , we will look a little more in detail at its operation to allow you to discover exactly 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 job of controlling the amount of oxygen present in the exhaust gases . One could naively think 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 adapt the quantity of air and gasoline injected into the engine unit to optimize the combustion .
Lambda sensor problem on Chevrolet Sonic
.
Finally, we are now going to attack the part you are absolutely most enthusiastic about this content, how to handle it if you have a lambda sensor problem on Chevrolet Sonic . In a first step we will discover how to identify a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Chevrolet Sonic is HS
.
It is necessary to know that a lambda sensor has in general a lifetime of 150 000 km , this data can vary according to the year of your Chevrolet Sonic, your driving, and the good working of your engine unit. A poorly taken care of engine unit that produces unburned gases may completely corrupt your lambda sensor. One of the clues that can notify you of a faulty lambda sensor on Chevrolet Sonic might be the engine unit light comes on, if you want to turn off the engine light of your Chevrolet Sonic, do not hesitate to consult our dedicated content to discover the process to stick to. The only effective way to ensure that you have a lambda sensor problem on your Chevrolet Sonic and to pass your car to the diagnostic case, for that do not hesitate to consult our tutorial which explains you Chevrolet Sonichow to read the fault code of a Chevrolet Sonic. Please be aware that if you have problems with one of your lambda sensors, the just solution to resolve them will be to change the faulty sensor.
How to change a lambda sensor on Chevrolet Sonic?
And at last, we are going to focus on the correction of lambda sensor problems on Chevrolet Sonic , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite very easy to accomplish and you will be able to do it yourself with a minimal of tools and mechanical knowledge. A lambda sensor is worth between 25 and 50€ , it is better to change 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 necessary to put your Chevrolet Sonic on candles and at the level of your catalyst unscrew your probes, disconnect them, reconnect them and screw the new ones . Once re-connected, you should not have any more problems with your lambda sensor on Chevrolet Sonic.
