Latest automobiles are more and more built with new technologies, apart from the comfort of use it can bring, technology as well has the advantage of saving fuel or reducing the pollution emitted by our automobiles. This is exactly the subject matter of our article content of the day, we are going to look at the complications of the lambda sensor on Ram ProMaster , this sensor as well named oxygen sensor plays an essential 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 Ram ProMaster and how to solve them.
What is a lambda role on Ram ProMaster?
So we begin our content page with the benefit of a lambda sensor on Ram ProMaster , we will first see what is the function of this probe and then how it functions.
Role of a lambda sensor on Ram ProMaster
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 Ram ProMaster , its goal 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 car and lower the car’s fuel consumption.
Lambda sensor operation on Ram ProMaster
Before describing you the different complications of lambda probe on Ram ProMaster , we will look a little more in detail at its working 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 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 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 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 injected into the engine to optimize the combustion .
Lambda sensor issue on Ram ProMaster
.
At last, we are now going to attack the part you are undoubtedly most keen on this content page, what to do if you have a lambda sensor issue on Ram ProMaster . In a first step we will discover how to locate a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Ram ProMaster is HS
.
It is essential to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this statistics can fluctuate according to the year of your Ram ProMaster, your driving, and the good functioning of your engine. A poorly taken care of engine that produces unburned gases may completely corrupt your lambda sensor. One of the clues that can notify you of a faulty lambda sensor on Ram ProMaster may be the engine light comes on, if you want to turn off the engine light of your Ram ProMaster, do not hesitate to seek advice from our dedicated content page to see the procedure to follow. The only effective way to be sure that you have a lambda sensor issue on your Ram ProMaster and to complete your car to the diagnostic case, for that do not hesitate to consult our guide which explains you Ram ProMasterhow to read the fault code of a Ram ProMaster. Please be aware that if you have complications with one of your lambda sensors, the just remedy to solve them will be to change the faulty sensor.
How to change a lambda sensor on Ram ProMaster?
And at last, we are going to concentrate on the correction of lambda sensor problems on Ram ProMaster , by describing how to replace a lambda sensor.
The replacement of a lambda sensor is quite simple to carry out and you will have the ability to do it yourself with a minimum of tools and mechanical know-how. 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 quickly. To replace it, it will be necessary to put your Ram ProMaster 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 Ram ProMaster.
