Latest automobiles are increasingly furnished with new technologies, apart from the comfort of use it can provide, technology as well has the advantage of saving fuel or reducing the pollution emitted by our automobiles. This is precisely the subject of our content of the day, we are going to look at the problems of the lambda sensor on Acura RDX , this sensor as well known as oxygen sensor plays an important function. To find out, first, we are going to find out what a lambda probe is used for, then, what are the lambda sensor problems on Acura RDX and how to fix them.
What is a lambda fonction on Acura RDX?
So we begin our article with the benefit of a lambda sensor on Acura RDX , we will first see what is the purpose of this probe and then how it functions.
Role of a lambda sensor on Acura RDX
First produced by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission requirements. As well called oxygen sensor on Acura RDX , its objective is to regulate the amount of oxygen in the exhaust gases, this will enable the engine to adapt the air/fuel mixture to decrease the pollution emitted by the car and reduce the car’s fuel consumption.
Lambda sensor procedure on Acura RDX
Before describing you the different problems of lambda probe on Acura RDX , we will look a little more in detail at its operation to allow you to figure out exactly how it functions and thus to consider more serenely the correction of a problem associated with it.
As we told you, a lambda probe has the task of managing the amount of oxygen present in the exhaust gases . One could naively presume 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 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 benefit is to have more precise 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 to improve the combustion .
Lambda sensor problem on Acura RDX
.
At last, we are now going to attack the part you are obviously most enthusiastic about this article, how to proceed if you have a lambda sensor problem on Acura RDX . In a first step we will discover how to identify a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Acura RDX is HS
.
It is important to know that a lambda sensor has in general a lifetime of 150 000 km , this data can differ according to the year of your Acura RDX, your driving, and the good functioning of your engine. A poorly looked after engine that produces unburned gases may permanently corrupt your lambda sensor. One of the clues that can warn you of a defective lambda sensor on Acura RDX may be the engine light turns on, if you want to turn off the engine light of your Acura RDX, do not hesitate to consult our dedicated article to see the procedure to follow. The only effective method to make sure that you have a lambda sensor problem on your Acura RDX and to complete your car to the diagnostic case, for that do not hesitate to seek advice from our tutorial which explains you Acura RDXhow to read the fault code of a Acura RDX. 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 Acura RDX?
And finally, we are going to focus on the correction of lambda sensor problems on Acura RDX , by detailing how to replace a lambda sensor.
The replacement of a lambda sensor is quite simple to perform and you will have the ability to do it yourself with a minimum of tools and mechanical know-how. 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 Acura RDX 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 Acura RDX.
