Recent automobiles are progressively equipped 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 precisely the subject matter of our content of the day, we are going to look at the problems of the lambda sensor on Honda Accord , this sensor also named oxygen sensor plays an essential role. To find out, first, we are going to find out what a lambda probe is utilized for, then, what are the lambda sensor problems on Honda Accord and how to resolve them.
What is a lambda fonction on Honda Accord?
So we begin our article with the benefit of a lambda sensor on Honda Accord , we will first see what is the function of this probe and then how it works.
Role of a lambda sensor on Honda Accord
First produced by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission standards. Also called oxygen sensor on Honda Accord , its goal is to regulate the amount of oxygen in the exhaust gases, this will allow the engine unit to change the air/fuel mixture to decrease the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.
Lambda sensor process on Honda Accord
Before explaining you the different problems of lambda probe on Honda Accord , we will look a little more in detail at its working to allow you to figure out precisely how it works and thus to consider more serenely the correction of a problem related to it.
As we told you, a lambda probe has the job of managing 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 only 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 benefit 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 inserted into the engine unit to optimize the combustion .
Lambda sensor issue on Honda Accord
.
Finally, we are now going to attack the part you are obviously most keen on this article, what to do if you have a lambda sensor issue on Honda Accord . In a first step we will find out how to find a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Honda Accord is HS
.
It is essential to know that a lambda sensor has generally a lifetime of 150 000 km , this info can vary according to the year of your Honda Accord, your driving, and the good functioning of your engine unit. A poorly maintained engine unit that emits unburned gases may forever corrupt your lambda sensor. One of the clues that can alert you of a defective lambda sensor on Honda Accord may be the engine unit light turns on, if you want to turn off the engine light of your Honda Accord, do not think twice to consult our dedicated article to see the process to follow. The only effective method to ensure that you have a lambda sensor issue on your Honda Accord and to pass your car to the diagnostic case, for that do not think twice to consult our guide which explains you Honda Accordhow to read the fault code of a Honda Accord. Please be aware that if you have problems with one of your lambda sensors, the only remedy to correct them will be to change the defective sensor.
How to change a lambda sensor on Honda Accord?
And at last, we are going to focus on the correction of lambda sensor problems on Honda Accord , by describing how to replace a lambda sensor.
The replacement of a lambda sensor is quite simple to carry out and you will have the ability to do it yourself with a lowest of tools and mechanical expertise. 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 defective the second one risks to drop you quickly. To replace it, it will be required to put your Honda Accord 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 Accord.
