Modern automobiles are increasingly pre-loaded 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 automobiles. This is precisely the subject of our article content of the day, we are going to look at the problems of the lambda sensor on Lexus GS , this sensor also called oxygen sensor plays an essential function. 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 Lexus GS and how to solve them.

What is a lambda task on Lexus GS?

So we start our content with the benefit of a lambda sensor on Lexus GS , we will first discover what is the job of this probe and then how it functions.

Role of a lambda sensor on Lexus GS

First created by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on Lexus GS , its task is to control the amount of oxygen in the exhaust gases, this will enable the engine to change the air/fuel mixture to lower the pollution released by the motor vehicle and lower the car’s fuel consumption.

Lambda sensor process on Lexus GS

Before describing you the different problems of lambda probe on Lexus GS , we will look a little more in detail at its operation to allow you to figure out 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 job of managing the amount of oxygen present in the exhaust gases . One could naively presume 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 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 to improve the combustion .

Lambda sensor problem on Lexus GS

.
At last, we are now going to attack the section you are undoubtedly most interested in this content, how to proceed if you have a lambda sensor problem on Lexus GS . In a first step we will find out how to find a lambda sensor HS and in a second step how to replace it.

How to know if a lambda sensor on Lexus GS 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 Lexus GS, your driving, and the good performance of your engine. A poorly maintained engine that emits unburned gases may permanently corrupt your lambda sensor. One of the clues that can warn you of a faulty lambda sensor on Lexus GS might be the engine light turns on, if you want to turn off the engine light of your Lexus GS, do not hesitate to visit our dedicated content to discover the procedure to stick to. The only effective way to be certain that you have a lambda sensor problem on your Lexus GS and to complete your car to the diagnostic case, for that do not hesitate to seek advice from our guide which explains you Lexus GShow to read the fault code of a Lexus GS. Take note that if you have problems with one of your lambda sensors, the just remedy to solve them will be to replace the faulty sensor.

How to replace a lambda sensor on Lexus GS?

And finally, we are going to focus on the correction of lambda sensor problems on Lexus GS , by detailing how to replace a lambda sensor.

The replacement of a lambda sensor is quite simple to accomplish and you will be able to do it yourself with a minimum of tools and mechanical expertise. 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 faulty the second one risks to drop you quickly. To replace it, it will be required to put your Lexus GS 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 Lexus GS.
