Modern cars 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 released by our cars. This is precisely the subject matter of our content of the day, we are going to look at the complications of the lambda sensor on Toyota 4Runner , this sensor as well known as 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 complications on Toyota 4Runner and how to resolve them.
What is a lambda task on Toyota 4Runner?
So we begin our content with the interest of a lambda sensor on Toyota 4Runner , we will first see what is the task of this probe and then how it functions.
Role of a lambda sensor on Toyota 4Runner
First produced 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 4Runner , its goal is to control the amount of oxygen in the exhaust gases, this will allow the engine to change the air/fuel mixture to lower the pollution released by the motor vehicle and reduce the car’s fuel consumption.
Lambda sensor process on Toyota 4Runner
Before explaining you the different complications of lambda probe on Toyota 4Runner , we will look a little more in outline 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 task of managing the amount of oxygen present in the exhaust gases . One could naively think that this data is calculated 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 specifications there are now 2 lambda sensors, one before and one after the catalyst . The interest is to have more precise 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 to improve the combustion .

.
Finally, we are now going to attack the part you are obviously most keen on this content, what to do if you have a lambda sensor problem on Toyota 4Runner . In a first step we will see how to find a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Toyota 4Runner is HS
.
It is important to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this data can vary according to the year of your Toyota 4Runner, your driving, and the good functioning of your engine. A poorly looked after engine that produces unburned gases may forever corrupt your lambda sensor. One of the clues that can notify you of a defective lambda sensor on Toyota 4Runner might be the engine light turns on, if you want to turn off the engine light of your Toyota 4Runner, do not hesitate to visit our dedicated content to see the process to follow. The only effective technique to be certain that you have a lambda sensor problem on your Toyota 4Runner and to pass your car to the diagnostic case, for that do not hesitate to seek advice from our tutorial which explains you Toyota 4Runnerhow to read the fault code of a Toyota 4Runner. Please note that if you have complications with one of your lambda sensors, the just solution to solve them will be to change the defective sensor.
How to change a lambda sensor on Toyota 4Runner?
And at last, we are going to concentrate on the correction of lambda sensor problems on Toyota 4Runner , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite basic to perform and you will be able to do it yourself with a minimal 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 Toyota 4Runner 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 complications with your lambda sensor on Toyota 4Runner.
