Modern vehicles are progressively built 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 vehicles. This is precisely the subject matter of our content page of the day, we are going to look at the complications of the lambda sensor on Toyota Corolla , this sensor as well named oxygen sensor plays an important role. To find out, first, we are going to find out what a lambda probe is used for, then, what are the lambda sensor complications on Toyota Corolla and how to fix them.

What is a lambda fonction on Toyota Corolla?

So we begin our content page with the benefit of a lambda sensor on Toyota Corolla , we will first see what is the job of this probe and then how it functions.

Role of a lambda sensor on Toyota Corolla

First designed by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission standards. As well called oxygen sensor on Toyota Corolla , its mission 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 released by the car and lower the car’s fuel consumption.

Lambda sensor operation on Toyota Corolla

Before describing you the different complications of lambda probe on Toyota Corolla , we will look a little more in outline at its functioning to allow you to understand precisely 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 task of controlling the amount of oxygen present in the exhaust gases . One could naively presume 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 standards there are now 2 lambda sensors, one before and one after the catalyst . The benefit is to have more precise 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 unit to optimize the combustion .

Lambda sensor problem on Toyota Corolla

.
At last, we are now going to attack the section you are undoubtedly most enthusiastic about this content page, what to do if you have a lambda sensor problem on Toyota Corolla . 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 Toyota Corolla is HS

.
It is important to know that a lambda sensor has generally a lifetime of 150 000 km , this data can differ according to the year of your Toyota Corolla, your driving, and the good functioning of your engine unit. A poorly taken care of engine unit that releases unburned gases may permanently alter your lambda sensor. One of the clues that can warn you of a faulty lambda sensor on Toyota Corolla might be the engine unit light comes on, if you want to turn off the engine light of your Toyota Corolla, do not think twice to visit our dedicated content page to see the process to follow. The only effective method to be certain that you have a lambda sensor problem on your Toyota Corolla and to complete your car to the diagnostic case, for that do not think twice to seek advice from our guide which explains you Toyota Corollahow to read the fault code of a Toyota Corolla. Please note that if you have complications with one of your lambda sensors, the just solution to correct them will be to change the faulty sensor.

How to change a lambda sensor on Toyota Corolla?

And at last, we are going to focus on the correction of lambda sensor problems on Toyota Corolla , by explaining how to replace a lambda sensor.

The replacement of a lambda sensor is quite very easy to carry out and you will have the ability to do it yourself with a minimal 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 faulty the second one risks to drop you quickly. To replace it, it will be necessary to put your Toyota Corolla 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 Corolla.
