Modern vehicles are progressively 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 vehicles. This is exactly the subject of our content of the day, we are going to look at the problems of the lambda sensor on Cadillac DTS , this sensor as well named oxygen sensor plays an necessary function. 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 Cadillac DTS and how to fix them.
What is a lambda purpose on Cadillac DTS?
So we begin our content with the interest of a lambda sensor on Cadillac DTS , we will first discover what is the task of this probe and then how it functions.
Role of a lambda sensor on Cadillac DTS
First developed by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on Cadillac DTS , its task is to control the amount of oxygen in the exhaust gases, this will allow the engine unit to adapt the air/fuel mixture to reduce the pollution released by the motor vehicle and reduce the car’s fuel consumption.
Lambda sensor process on Cadillac DTS
Before describing you the different problems of lambda probe on Cadillac DTS , we will look a little more in outline at its functioning to allow you to figure out exactly 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 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 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 adjust the quantity of air and gasoline injected into the engine unit to improve the combustion .
Lambda sensor issue on Cadillac DTS
.
Finally, we are now going to attack the part you are obviously most interested in this content, how to proceed if you have a lambda sensor issue on Cadillac DTS . In a first step we will find out how to locate a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Cadillac DTS is HS
.
It is necessary 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 Cadillac DTS, your driving, and the good working of your engine unit. A poorly looked after engine unit that produces unburned gases may completely damaged your lambda sensor. One of the clues that can warn you of a faulty lambda sensor on Cadillac DTS might be the engine unit light turns on, if you want to turn off the engine light of your Cadillac DTS, do not hesitate to consult our dedicated content to discover the process to stick to. The only effective method to be sure that you have a lambda sensor issue on your Cadillac DTS and to complete your car to the diagnostic case, for that do not hesitate to seek advice from our tutorial which explains you Cadillac DTShow to read the fault code of a Cadillac DTS. Take note that if you have problems with one of your lambda sensors, the just solution to resolve them will be to replace the faulty sensor.
How to replace a lambda sensor on Cadillac DTS?
And finally, we are going to focus on the correction of lambda sensor problems on Cadillac DTS , by describing 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 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 required to put your Cadillac DTS 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 Cadillac DTS.
