Modern automobiles are increasingly furnished with new technologies, apart from the comfort of use it can provide, technology also has the advantage of saving fuel or reducing the pollution emitted by our automobiles. 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 Scion xB , this sensor also named oxygen sensor plays an necessary role. 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 Scion xB and how to resolve them.

What is a lambda role on Scion xB?

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

Role of a lambda sensor on Scion xB

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 Scion xB , its task is to regulate the amount of oxygen in the exhaust gases, this will allow the engine to modify the air/fuel mixture to lower the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.

Lambda sensor procedure on Scion xB

Before explaining you the different complications of lambda probe on Scion xB , we will look a little more in detail at its working to allow you to discover precisely how it functions and thus to consider more serenely the correction of a problem related to it.
As we informed you, a lambda probe has the task 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 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 modify the quantity of air and gasoline inserted into the engine to improve the combustion .

Lambda sensor problem on Scion xB

.
Finally, we are now going to attack the section you are obviously most interested in this content, how to proceed if you have a lambda sensor problem on Scion xB . In a first step we will see how to identify a lambda sensor HS and in a second step how to replace it.

How to know if a lambda sensor on Scion xB is HS

.
It is necessary to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this info can vary according to the year of your Scion xB, your driving, and the good working of your engine. A poorly looked after engine that releases unburned gases may forever corrupt your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Scion xB may be the engine light comes on, if you want to turn off the engine light of your Scion xB, do not think twice to consult our dedicated content to see the process to follow. The only effective technique to make sure that you have a lambda sensor problem on your Scion xB and to complete your car to the diagnostic case, for that do not think twice to consult our guide which explains you Scion xBhow to read the fault code of a Scion xB. Take note that if you have complications with one of your lambda sensors, the just solution to correct them will be to replace the faulty sensor.

How to replace a lambda sensor on Scion xB?

And finally, we are going to concentrate on the correction of lambda sensor problems on Scion xB , by detailing how to replace a lambda sensor.

The replacement of a lambda sensor is quite very easy to perform and you will be able 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 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 Scion xB 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 Scion xB.
