Recent vehicles are increasingly furnished 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 released by our vehicles. This is exactly the subject of our article of the day, we are going to look at the problems of the lambda sensor on Ram ProMaster City , this sensor as well called oxygen sensor plays an necessary purpose. To find out, first, we are going to find out what a lambda probe is utilized for, then, what are the lambda sensor problems on Ram ProMaster City and how to resolve them.

What is a lambda task on Ram ProMaster City?

So we start our content with the interest of a lambda sensor on Ram ProMaster City , we will first discover what is the task of this probe and then how it works.

Role of a lambda sensor on Ram ProMaster City

First developed by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on Ram ProMaster City , its objective is to control the amount of oxygen in the exhaust gases, this will allow the engine to modify the air/fuel mixture to decrease the pollution released by the motor vehicle and lower the car’s fuel consumption.

Lambda sensor procedure on Ram ProMaster City

Before describing you the different problems of lambda probe on Ram ProMaster City , we will look a little more in outline at its operation to allow you to discover precisely how it works 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 controlling 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 interest is to have more precise data by compiling the two probes. These data are sent to the ECU which will adapt the quantity of air and gasoline inserted into the engine to optimize the combustion .

Lambda sensor problem on Ram ProMaster City

.
Finally, we are now going to attack the part you are absolutely most enthusiastic about this content, how to proceed if you have a lambda sensor problem on Ram ProMaster City . In a first step we will discover how to find a lambda sensor HS and in a second step how to replace it.

How to know if a lambda sensor on Ram ProMaster City is HS

.
It is necessary to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this info can differ according to the year of your Ram ProMaster City, your driving, and the good working of your engine. A poorly taken care of engine that releases unburned gases may forever alter your lambda sensor. One of the clues that can alert you of a defective lambda sensor on Ram ProMaster City may be the engine light turns on, if you want to turn off the engine light of your Ram ProMaster City, do not think twice to visit our dedicated content to discover the process to stick to. The only effective way to be sure that you have a lambda sensor problem on your Ram ProMaster City and to pass your car to the diagnostic case, for that do not think twice to seek advice from our tutorial which explains you Ram ProMaster Cityhow to read the fault code of a Ram ProMaster City. Please be aware that if you have problems with one of your lambda sensors, the just solution to solve them will be to replace the defective sensor.

How to replace a lambda sensor on Ram ProMaster City?

And at last, we are going to concentrate on the correction of lambda sensor problems on Ram ProMaster City , 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 lowest 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 defective the second one risks to drop you fairly quickly. To replace it, it will be required to put your Ram ProMaster City 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 Ram ProMaster City.
