Recent vehicles are increasingly 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 of the day, we are going to look at the complications of the lambda sensor on Lexus IS , this sensor also named oxygen sensor plays an necessary function. To find out, first, we are going to find out what a lambda probe is employed for, then, what are the lambda sensor complications on Lexus IS and how to solve them.
What is a lambda task on Lexus IS?
So we begin our article with the benefit of a lambda sensor on Lexus IS , we will first see what is the purpose of this probe and then how it functions.
Role of a lambda sensor on Lexus IS
First produced 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 IS , its objective is to control the amount of oxygen in the exhaust gases, this will allow the engine unit to change the air/fuel mixture to reduce the pollution released by the motor vehicle and lower the car’s fuel consumption.
Lambda sensor procedure on Lexus IS
Before describing you the different complications of lambda probe on Lexus IS , we will look a little more in outline at its functioning to allow you to discover exactly 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 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 requirements there are now 2 lambda sensors, one before and one after the catalyst . The benefit 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 unit to improve the combustion .
Lambda sensor problem on Lexus IS
.
Finally, we are now going to attack the section you are absolutely most keen on this article, what to do if you have a lambda sensor problem on Lexus IS . In a first step we will see 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 IS is HS
.
It is necessary to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this statistics can vary according to the year of your Lexus IS, your driving, and the good performance of your engine unit. A poorly maintained engine unit that produces unburned gases may forever alter your lambda sensor. One of the clues that can notify you of a faulty lambda sensor on Lexus IS may be the engine unit light turns on, if you want to turn off the engine light of your Lexus IS, do not hesitate to seek advice from our dedicated article to see the procedure to follow. The only effective way to make sure that you have a lambda sensor problem on your Lexus IS and to pass your car to the diagnostic case, for that do not hesitate to seek advice from our tutorial which explains you Lexus IShow to read the fault code of a Lexus IS. Take note that if you have complications with one of your lambda sensors, the just remedy to resolve them will be to replace the faulty sensor.
How to replace a lambda sensor on Lexus IS?
And finally, we are going to focus on the correction of lambda sensor problems on Lexus IS , by detailing 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 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 fairly quickly. To replace it, it will be required to put your Lexus IS 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 IS.
In the event that you have any further questions about the Lexus IS, do not hesitate to consult our Lexus IS category.
