Latest automobiles are more and more pre-loaded 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 released by our automobiles. This is precisely the subject of our content of the day, we are going to look at the problems of the lambda sensor on Dodge Grand Caravan , this sensor as well named oxygen sensor plays an important 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 Dodge Grand Caravan and how to solve them.
What is a lambda role on Dodge Grand Caravan?
So we begin our content with the benefit of a lambda sensor on Dodge Grand Caravan , we will first discover what is the purpose of this probe and then how it works.
Role of a lambda sensor on Dodge Grand Caravan
First created by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission requirements. As well called oxygen sensor on Dodge Grand Caravan , its goal is to regulate the amount of oxygen in the exhaust gases, this will allow the engine unit to modify the air/fuel mixture to reduce the pollution released by the car and lower the car’s fuel consumption.
Lambda sensor process on Dodge Grand Caravan
Before describing you the different problems of lambda probe on Dodge Grand Caravan , we will look a little more in detail at its working to allow you to figure out precisely how it works 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 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 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 benefit 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 .

.
Finally, we are now going to attack the part you are obviously most keen on this content, how to handle it if you have a lambda sensor issue on Dodge Grand Caravan . In a first step we will find out how to identify a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Dodge Grand Caravan is HS
.
It is important to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this data can fluctuate according to the year of your Dodge Grand Caravan, your driving, and the good performance of your engine unit. A poorly looked after engine unit that releases unburned gases may completely alter your lambda sensor. One of the clues that can notify you of a defective lambda sensor on Dodge Grand Caravan might be the engine unit light turns on, if you want to turn off the engine light of your Dodge Grand Caravan, do not think twice to seek advice from our dedicated content to discover the process to follow. The only effective method to make sure that you have a lambda sensor issue on your Dodge Grand Caravan and to complete your car to the diagnostic case, for that do not think twice to seek advice from our tutorial which explains you Dodge Grand Caravanhow to read the fault code of a Dodge Grand Caravan. Please be aware that if you have problems with one of your lambda sensors, the just remedy to correct them will be to replace the defective sensor.
How to replace a lambda sensor on Dodge Grand Caravan?
And at last, we are going to focus on the correction of lambda sensor problems on Dodge Grand Caravan , by detailing how to replace a lambda sensor.
The replacement of a lambda sensor is quite basic to perform and you will have the ability to do it yourself with a lowest 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 defective the second one risks to drop you quickly. To replace it, it will be required to put your Dodge Grand Caravan 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 Dodge Grand Caravan.
