Latest vehicles are progressively equipped with new technologies, apart from the comfort of use it can provide, technology also has the advantage of saving fuel or reducing the pollution released by our vehicles. This is exactly the subject matter of our content page of the day, we are going to look at the problems of the lambda sensor on Toyota 86 , this sensor also known as oxygen sensor plays an essential 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 86 and how to resolve them.


What is a lambda purpose on Toyota 86?

So we start our content with the interest of a lambda sensor on Toyota 86 , we will first discover what is the task of this probe and then how it works.

Role of a lambda sensor on Toyota 86

First produced by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission specifications. As well called oxygen sensor on Toyota 86 , its goal is to regulate the amount of oxygen in the exhaust gases, this will enable the engine to adapt the air/fuel mixture to reduce the pollution released by the motor vehicle and lower the car’s fuel consumption.

Lambda sensor process on Toyota 86

Before explaining you the different problems of lambda probe on Toyota 86 , we will look a little more in detail at its working to allow you to understand exactly how it works 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 managing the amount of oxygen present in the exhaust gases . One could naively believe 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 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 adapt the quantity of air and gasoline injected into the engine to improve the combustion .

Lambda sensor issue on Toyota 86

At last, we are now going to attack the part you are obviously most keen on this content, how to handle it if you have a lambda sensor issue on Toyota 86 . In a first step we will find out how to identify a lambda sensor HS and in a second step how to replace it.

How to know if a lambda sensor on Toyota 86 is HS

It is essential 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 86, your driving, and the good functioning of your engine. A poorly taken care of engine that emits unburned gases may forever alter your lambda sensor. One of the clues that can notify you of a defective lambda sensor on Toyota 86 might be the engine light turns on, if you want to turn off the engine light of your Toyota 86, do not hesitate to seek advice from our dedicated content to discover the process to follow. The only effective method to make sure that you have a lambda sensor issue on your Toyota 86 and to pass your car to the diagnostic case, for that do not hesitate to consult our guide which explains you Toyota 86how to read the fault code of a Toyota 86. Please note that if you have problems with one of your lambda sensors, the just solution to resolve them will be to replace the defective sensor.

How to replace a lambda sensor on Toyota 86?

And finally, we are going to focus on the correction of lambda sensor problems on Toyota 86 , by detailing 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 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 quickly. To replace it, it will be required to put your Toyota 86 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 86.
