Latest vehicles are progressively furnished 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 vehicles. This is precisely the subject matter of our content of the day, we are going to look at the problems of the lambda sensor on Toyota C HR , this sensor also called oxygen sensor plays an essential purpose. To find out, first, we are going to find out what a lambda probe is employed for, then, what are the lambda sensor problems on Toyota C HR and how to resolve them.
What is a lambda purpose on Toyota C HR?
So we begin our content page with the interest of a lambda sensor on Toyota C HR , we will first discover what is the job of this probe and then how it functions.
Role of a lambda sensor on Toyota C HR
First designed 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 Toyota C HR , its mission is to regulate the amount of oxygen in the exhaust gases, this will enable the engine unit to adapt the air/fuel mixture to decrease the pollution released by the motor vehicle and lower the car’s fuel consumption.
Lambda sensor procedure on Toyota C HR
Before describing you the different problems of lambda probe on Toyota C HR , 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 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 determined 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 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 interest 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 injected into the engine unit to improve the combustion .
Lambda sensor issue on Toyota C HR
.
Finally, we are now going to attack the section you are obviously most keen on this content page, what to do if you have a lambda sensor issue on Toyota C HR . 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 Toyota C HR is HS
.
It is essential to know that a lambda sensor has generally a lifetime of 150 000 km , this info can vary according to the year of your Toyota C HR, your driving, and the good functioning of your engine unit. A poorly maintained engine unit that releases unburned gases may forever damaged your lambda sensor. One of the clues that can warn you of a faulty lambda sensor on Toyota C HR may be the engine unit light comes on, if you want to turn off the engine light of your Toyota C HR, do not hesitate to consult our dedicated content page to discover the process to stick to. The only effective way to make sure that you have a lambda sensor issue on your Toyota C HR and to complete your car to the diagnostic case, for that do not hesitate to consult our tutorial which explains you Toyota C HRhow to read the fault code of a Toyota C HR. Take note that if you have problems with one of your lambda sensors, the only remedy to resolve them will be to replace the faulty sensor.
How to replace a lambda sensor on Toyota C HR?
And finally, we are going to concentrate on the correction of lambda sensor problems on Toyota C HR , 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 know-how. 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 necessary to put your Toyota C HR 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 Toyota C HR.
