The particle filter indicator light turns on and you don't know where the problem is coming from. The particle filter is present especially in cars Diesel, even if we now find them in petrol cars. Before you get into repairs in your Kia Sorento 2, it is essential to understand where the malfunction comes from. What is the role of a particle filter? Why does the light come on? What are the most regular dysfunctions? In this article, we will go over the subject. 
What is a FAP on your Kia Sorento 2 for?
As its designation suggests, its role is to filter out microscopic molecules harmful of the vehicle. These molecules are so tiny that they can easily enter your body. It is also Peugeot who invented the particulate filter. The catalyst is used to reduce the dose of molecules generated from the engine, while the particle filter collects the remains. It therefore seems essential to have a particle filter in good condition if you do not want your Kia Sorento 2 to pollute.
Why the FAP indicator lights on your Kia Sorento 2
The FAP of your Kia Sorento 2 is clogged
This is the most common problem. And that's normal, the particle filter becomes clogged the more time passes. Molecules pile up and thus interfere with the proper circulation of your exhaust gases. Ordinarily, the particle filter of your Kia Sorento 2 will be able to purge itself automatically and therefore expel this waste. On the other hand, if this one is particularly old it is essential to replace it with a new one.
An electronic problem
The problem with the LEDs is that you are by no means sure you have a problem. Indeed, it sometimes happens that an indicator light shines while your Kia Sorento 2 is working properly. Your particle filter has several electronic probes which transmit the signal to your indicator. If your sensors do not work well while your particle filter is doing well, it is likely that the indicator light is on.
What to do if the FAP indicator on your Kia Sorento 2 lights up?
Above all, it is absolutely illegal to remove the fap on your Kia Sorento 2! This is punishable by law. You can examine the sensors to see if they work properly. If these ever work well, the dysfunction must come from the FAP. If it turns out to be filthy, it can be repaired by driving on excessive speed for 10 to 15 minutes. Do not climb too much in the towers, the process could damage the car. We advise you to go up to 3000 rpm. The engine block temperature will therefore burn the stored dirt, and therefore purify the particulate filter. If such a method still does not work, it must be replaced by a new one.
