Recent cars are increasingly built with new technologies, apart from the comfort of use it can bring, technology also has the advantage of saving fuel or reducing the pollution released by our cars. This is exactly the subject matter of our article content of the day, we are going to look at the problems of the lambda sensor on Lexus RX , this sensor also named oxygen sensor plays an necessary role. 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 Lexus RX and how to resolve them.
What is a lambda fonction on Lexus RX?
So we begin our article with the benefit of a lambda sensor on Lexus RX , we will first discover what is the job of this probe and then how it functions.
Role of a lambda sensor on Lexus RX
First created 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 Lexus RX , its mission 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 released by the car and lower the car’s fuel consumption.
Lambda sensor operation on Lexus RX
Before explaining you the different problems of lambda probe on Lexus RX , we will look a little more in outline at its operation to allow you to understand exactly how it functions 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 think 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 only one lambda sensor required 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 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 to optimize the combustion .

.
Finally, we are now going to attack the section you are certainly most interested in this article, what to do if you have a lambda sensor problem on Lexus RX . In a first step we will discover how to find a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Lexus RX is HS
.
It is necessary to know that a lambda sensor has in general a lifetime of 150 000 km , this statistics can fluctuate according to the year of your Lexus RX, your driving, and the good performance of your engine. A poorly maintained engine that produces unburned gases may completely alter your lambda sensor. One of the clues that can warn you of a faulty lambda sensor on Lexus RX might be the engine light turns on, if you want to turn off the engine light of your Lexus RX, do not think twice to consult our dedicated article to discover the procedure to follow. The only effective technique to be certain that you have a lambda sensor problem on your Lexus RX and to pass your car to the diagnostic case, for that do not think twice to consult our guide which explains you Lexus RXhow to read the fault code of a Lexus RX. Please note that if you have problems with one of your lambda sensors, the only solution to correct them will be to change the faulty sensor.
How to change a lambda sensor on Lexus RX?
And finally, we are going to concentrate on the correction of lambda sensor problems on Lexus RX , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite basic to carry out and you will have the ability 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 quickly. To replace it, it will be required to put your Lexus RX 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 Lexus RX.
