Recent vehicles are increasingly built 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 vehicles. This is precisely the subject matter of our article of the day, we are going to look at the complications of the lambda sensor on Toyota Prius , this sensor also named oxygen sensor plays an essential purpose. To find out, first, we are going to identify what a lambda probe is employed for, then, what are the lambda sensor complications on Toyota Prius and how to resolve them.
What is a lambda task on Toyota Prius?
So we begin our content page with the interest of a lambda sensor on Toyota Prius , we will first discover what is the role of this probe and then how it functions.
Role of a lambda sensor on Toyota Prius
First produced by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission specifications. As well called oxygen sensor on Toyota Prius , its goal is to control the amount of oxygen in the exhaust gases, this will allow the engine unit to change the air/fuel mixture to decrease the pollution emitted by the car and lower the car’s fuel consumption.
Lambda sensor operation on Toyota Prius
Before explaining you the different complications of lambda probe on Toyota Prius , we will look a little more in outline at its operation to allow you to figure out precisely how it functions and thus to consider more serenely the correction of a problem related to it.
As we explained to you, a lambda probe has the job of controlling 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 only one lambda sensor needed before the catalyst, but with the arrival of more drastic specifications there are now 2 lambda sensors, one before and one after the catalyst . The interest is to have more precise 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 unit to improve the combustion .
Lambda sensor issue on Toyota Prius
.
Finally, we are now going to attack the part you are obviously most enthusiastic about this content page, how to handle it if you have a lambda sensor issue on Toyota Prius . In a first step we will see how to identify a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Toyota Prius is HS
.
It is essential to know that a lambda sensor has generally a lifetime of 150 000 km , this data can fluctuate according to the year of your Toyota Prius, your driving, and the good functioning of your engine unit. A poorly maintained engine unit that releases unburned gases may completely corrupt your lambda sensor. One of the clues that can warn you of a faulty lambda sensor on Toyota Prius may be the engine unit light turns on, if you want to turn off the engine light of your Toyota Prius, do not think twice to seek advice from our dedicated content page to discover the procedure to stick to. The only effective way to be sure that you have a lambda sensor issue on your Toyota Prius and to pass your car to the diagnostic case, for that do not think twice to seek advice from our tutorial which explains you Toyota Priushow to read the fault code of a Toyota Prius. Take note that if you have complications with one of your lambda sensors, the only solution to resolve them will be to change the faulty sensor.
How to change a lambda sensor on Toyota Prius?
And finally, we are going to concentrate on the correction of lambda sensor problems on Toyota Prius , 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 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 fairly quickly. To replace it, it will be necessary to put your Toyota Prius 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 Prius.
