Latest cars are more and more pre-loaded with new technologies, apart from the comfort of use it can bring, technology also 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 Lexus GX , this sensor also called oxygen sensor plays an important purpose. To find out, first, we are going to find out what a lambda probe is utilized for, then, what are the lambda sensor complications on Lexus GX and how to resolve them.

What is a lambda task on Lexus GX?

So we start our article with the benefit of a lambda sensor on Lexus GX , we will first see what is the job of this probe and then how it works.

Role of a lambda sensor on Lexus GX

First developed 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 Lexus GX , its mission is to control 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 motor vehicle and reduce the car’s fuel consumption.

Lambda sensor process on Lexus GX

Before explaining you the different complications of lambda probe on Lexus GX , we will look a little more in outline at its operation to allow you to figure out precisely how it works and thus to consider more serenely the correction of a problem associated with 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 determined 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 benefit 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 unit to improve the combustion .

.
Finally, we are now going to attack the part you are obviously most interested in this article, how to handle it if you have a lambda sensor problem on Lexus GX . In a first step we will discover how to locate a lambda sensor HS and in a second step how to change it.

How to know if a lambda sensor on Lexus GX is HS

.
It is important to know that a lambda sensor has generally a lifetime of 150 000 km , this data can vary according to the year of your Lexus GX, your driving, and the good working of your engine unit. A poorly maintained engine unit that emits unburned gases may completely alter your lambda sensor. One of the clues that can warn you of a faulty lambda sensor on Lexus GX may be the engine unit light comes on, if you want to turn off the engine light of your Lexus GX, do not hesitate to visit our dedicated article to see the process to stick to. The only effective technique to make sure that you have a lambda sensor problem on your Lexus GX and to complete your car to the diagnostic case, for that do not hesitate to seek advice from our tutorial which explains you Lexus GXhow to read the fault code of a Lexus GX. Please note that if you have complications with one of your lambda sensors, the just solution to resolve them will be to change the faulty sensor.

How to change a lambda sensor on Lexus GX?

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

The replacement of a lambda sensor is quite very easy to execute and you will have the ability to do it yourself with a minimal of tools and mechanical knowledge. 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 Lexus GX 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 Lexus GX.
