Recent automobiles are progressively 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 exactly the subject of our content of the day, we are going to look at the problems of the lambda sensor on Toyota RAV4 , this sensor as well called oxygen sensor plays an important 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 Toyota RAV4 and how to fix them.
What is a lambda purpose on Toyota RAV4?
So we begin our article with the interest of a lambda sensor on Toyota RAV4 , we will first discover what is the function of this probe and then how it functions.
Role of a lambda sensor on Toyota RAV4
First designed by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission specifications. As well called oxygen sensor on Toyota RAV4 , its goal is to regulate the amount of oxygen in the exhaust gases, this will allow the engine unit to adapt the air/fuel mixture to lower the pollution emitted by the motor vehicle and lower the car’s fuel consumption.
Lambda sensor process on Toyota RAV4
Before explaining you the different problems of lambda probe on Toyota RAV4 , we will look a little more in detail at its working 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 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 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 specifications 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 adjust the quantity of air and gasoline inserted into the engine unit to improve the combustion .

.
Finally, we are now going to attack the section you are obviously most interested in this article, what to do if you have a lambda sensor problem on Toyota RAV4 . In a first step we will discover how to locate a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Toyota RAV4 is HS
.
It is important to know that a lambda sensor has in general a lifetime of 150 000 km , this statistics can vary according to the year of your Toyota RAV4, your driving, and the good working of your engine unit. A poorly looked after engine unit that releases unburned gases may permanently alter your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Toyota RAV4 might be the engine unit light turns on, if you want to turn off the engine light of your Toyota RAV4, do not hesitate to visit our dedicated article to discover the process to stick to. The only effective method to be certain that you have a lambda sensor problem on your Toyota RAV4 and to pass your car to the diagnostic case, for that do not hesitate to consult our tutorial which explains you Toyota RAV4how to read the fault code of a Toyota RAV4. Take note that if you have problems with one of your lambda sensors, the only solution to resolve them will be to replace the faulty sensor.
How to replace a lambda sensor on Toyota RAV4?
And at last, we are going to concentrate on the correction of lambda sensor problems on Toyota RAV4 , by detailing 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 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 faulty the second one risks to drop you fairly quickly. To replace it, it will be necessary to put your Toyota RAV4 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 Toyota RAV4.
