Recent automobiles are increasingly furnished with new technologies, apart from the comfort of use it can provide, technology as well has the advantage of saving fuel or reducing the pollution emitted by our automobiles. 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 P/U , this sensor as well named oxygen sensor plays an important purpose. To find out, first, we are going to identify what a lambda probe is used for, then, what are the lambda sensor problems on Ram P/U and how to fix them.
What is a lambda fonction on Ram P/U?
So we begin our content with the interest of a lambda sensor on Ram P/U , we will first discover what is the purpose of this probe and then how it functions.
Role of a lambda sensor on Ram P/U
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 Ram P/U , its objective is to control the amount of oxygen in the exhaust gases, this will enable the engine unit to change the air/fuel mixture to reduce the pollution emitted by the car and lower the car’s fuel consumption.
Lambda sensor process on Ram P/U
Before explaining you the different problems of lambda probe on Ram P/U , we will look a little more in detail at its functioning to allow you to understand exactly how it functions and thus to consider more serenely the correction of a problem associated with it.
As we informed you, a lambda probe has the job of controlling the amount of oxygen present in the exhaust gases . One could naively believe 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 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 interest 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 unit to optimize the combustion .
Lambda sensor issue on Ram P/U
.
Finally, we are now going to attack the part you are absolutely most keen on this content, what to do if you have a lambda sensor issue on Ram P/U . 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 P/U is HS
.
It is important to know that a lambda sensor has in general a lifetime of 150 000 km , this statistics can vary according to the year of your Ram P/U, your driving, and the good performance of your engine unit. A poorly looked after engine unit that emits unburned gases may completely alter your lambda sensor. One of the clues that can notify you of a faulty lambda sensor on Ram P/U may be the engine unit light turns on, if you want to turn off the engine light of your Ram P/U, do not think twice to consult our dedicated content to discover the procedure to stick to. The only effective way to be certain that you have a lambda sensor issue on your Ram P/U and to complete your car to the diagnostic case, for that do not think twice to seek advice from our guide which explains you Ram P/Uhow to read the fault code of a Ram P/U. Please note that if you have problems with one of your lambda sensors, the just remedy to resolve them will be to replace the faulty sensor.
How to replace a lambda sensor on Ram P/U?
And finally, we are going to concentrate on the correction of lambda sensor problems on Ram P/U , by describing 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 minimum 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 fairly quickly. To replace it, it will be necessary to put your Ram P/U 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 P/U.
