Your particle filter indicator light is on and you don't know where the problem is coming from. The particle filter is mainly found in cars Diesel, even though we find them more and more in gasoline cars. Before you start repairs in your Kia Soul 2, it is important to know where this malfunction comes from. How does a FAP work? Why does the indicator light go off? What can be the most common problems? During this file, we will go around the question. 
What is a FAP on your Kia Soul 2 for?
As its designation indicates, its role is to filter microscopic molecules toxiques of your car. These molecules are so tiny that they can easily enter our body. For information, it's Peugeot who developed this FAP. Your catalyst's role is to reduce the level of molecules produced by the engine, while the FAP collects waste. It therefore remains necessary to have an operational FAP in case you no longer want your Kia Soul 2 to contaminate the air you inhale.
Why the FAP indicator lights on your Kia Soul 2
The FAP of your Kia Soul 2 is clogged
This is the most common concern. Indeed, your FAP becomes clogged as time goes by. The molecules form clusters and prevent the flow of exhaust gases. A priori, the FAP of your Kia Soul 2 can be purged alone and therefore make this waste go away. On the other hand, if it is too old you must replace it.
An electronic problem
The problem for LEDs is that you are in no way sure of the problem. For example, it sometimes happens that an indicator light goes off while your Kia Soul 2 is running without worries. The FAP has several electronic sensors which transmit a message to your dashboard. If these sensors do not work well while this FAP is working properly, it remains possible that your indicator light is on.
What to do if the FAP indicator on your Kia Soul 2 lights up?
Above all, it is completely prohibited to remove the fap from your Kia Soul 2! This is an offense. You can check the probes to see if they work well. If the latter ever work properly, the malfunction comes from the Particle filter. If it turns out to be filthy, it can be unclogged by rolling in the towers for 10 minutes. Do not accelerate too much either, the process could damage the car. We advise you to go up to 3000 revolutions minutes. The engine temperature will cause the stored soot to burn out, thereby purifying the FAP. When such a method is not suitable, it is necessary to change it.
Conclusion:
The particle filter in poor condition can pollute and reduce the power of the vehicle. It is therefore essential to have it changed. Write a comment in case this file was useful. See you soon !
