Modern cars are more and more pre-loaded with new technologies, apart from the comfort of use it can bring, technology also has the advantage of saving fuel or reducing the pollution emitted by our cars. This is exactly the subject matter of our content page of the day, we are going to look at the problems of the lambda sensor on Honda Civic , this sensor also named oxygen sensor plays an important role. To find out, first, we are going to find out what a lambda probe is employed for, then, what are the lambda sensor problems on Honda Civic and how to fix them.
What is a lambda fonction on Honda Civic?
So we start our content with the interest of a lambda sensor on Honda Civic , we will first discover what is the purpose of this probe and then how it works.
Role of a lambda sensor on Honda Civic
First created by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission standards. As well called oxygen sensor on Honda Civic , its task is to control the amount of oxygen in the exhaust gases, this will enable the engine unit to adapt the air/fuel mixture to lower the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.
Lambda sensor procedure on Honda Civic
Before describing you the different problems of lambda probe on Honda Civic , we will look a little more in detail at its functioning to allow you to figure out precisely how it works and thus to consider more serenely the correction of a problem associated with it.
As we explained to you, a lambda probe has the job of controlling the amount of oxygen present in the exhaust gases . One could naively believe that this data is measured 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 interest 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 optimize the combustion .
Lambda sensor problem on Honda Civic
.
At last, we are now going to attack the part you are certainly most interested in this content, how to handle it if you have a lambda sensor problem on Honda Civic . In a first step we will see how to find a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Honda Civic is HS
.
It is important to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this statistics can differ according to the year of your Honda Civic, your driving, and the good performance of your engine unit. A poorly taken care of engine unit that produces unburned gases may forever corrupt your lambda sensor. One of the clues that can warn you of a defective lambda sensor on Honda Civic may be the engine unit light turns on, if you want to turn off the engine light of your Honda Civic, do not think twice to visit our dedicated content to discover the process to follow. The only effective technique to be certain that you have a lambda sensor problem on your Honda Civic and to pass your car to the diagnostic case, for that do not think twice to consult our guide which explains you Honda Civichow to read the fault code of a Honda Civic. Take note that if you have problems with one of your lambda sensors, the just remedy to solve them will be to replace the defective sensor.
How to replace a lambda sensor on Honda Civic?
And finally, we are going to concentrate on the correction of lambda sensor problems on Honda Civic , by detailing how to replace a lambda sensor.
The replacement of a lambda sensor is quite very easy to execute 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 defective the second one risks to drop you fairly quickly. To replace it, it will be necessary to put your Honda Civic 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 Honda Civic.
