Modern cars are increasingly furnished 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 cars. This is exactly the subject matter of our content of the day, we are going to look at the problems of the lambda sensor on Toyota FJ Cruiser , this sensor also known as oxygen sensor plays an important function. To find out, first, we are going to identify what a lambda probe is utilized for, then, what are the lambda sensor problems on Toyota FJ Cruiser and how to solve them.
What is a lambda fonction on Toyota FJ Cruiser?
So we begin our content page with the interest of a lambda sensor on Toyota FJ Cruiser , we will first discover what is the job of this probe and then how it works.
Role of a lambda sensor on Toyota FJ Cruiser
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 Toyota FJ Cruiser , its goal is to control 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 car and lower the car’s fuel consumption.
Lambda sensor operation on Toyota FJ Cruiser
Before explaining you the different problems of lambda probe on Toyota FJ Cruiser , we will look a little more in outline at its functioning to allow you to discover 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 task of managing 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 just 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 interest is to have more exact data by compiling the two probes. These data are sent to the ECU which will modify the quantity of air and gasoline injected into the engine unit to optimize the combustion .

.
At last, we are now going to attack the part you are certainly most interested in this content page, how to handle it if you have a lambda sensor issue on Toyota FJ Cruiser . 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 Toyota FJ Cruiser is HS
.
It is important to know that a lambda sensor has in general a lifetime of 150 000 km , this info can differ according to the year of your Toyota FJ Cruiser, your driving, and the good performance of your engine unit. A poorly looked after engine unit that releases unburned gases may completely alter your lambda sensor. One of the clues that can warn you of a defective lambda sensor on Toyota FJ Cruiser might be the engine unit light comes on, if you want to turn off the engine light of your Toyota FJ Cruiser, do not hesitate to visit our dedicated content page to discover the process to follow. The only effective technique to ensure that you have a lambda sensor issue on your Toyota FJ Cruiser and to pass your car to the diagnostic case, for that do not hesitate to seek advice from our guide which explains you Toyota FJ Cruiserhow to read the fault code of a Toyota FJ Cruiser. Please be aware that if you have problems 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 FJ Cruiser?
And at last, we are going to concentrate on the correction of lambda sensor problems on Toyota FJ Cruiser , by describing 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 minimum of tools and mechanical know-how. 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 necessary to put your Toyota FJ Cruiser 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 FJ Cruiser.
