The FAP warning light turns on and you do not know where the malfunction is coming from. The FAP exists mainly for cars Diesel, even though we will now see some for petrol cars. Just before you start repairs for the Kia Carens 3, it's important to understand where the problem is coming from. What is a particle filter used for? Why does the light come on? What are the most common concerns? In this text, we will go around the subject. 
What is a FAP for on your Kia Carens 3
As its name suggests, its role is to filter out microscopic molecules harmful of the engine block. These molecules are so tiny that they easily fit through your body. For your information, it is Peugeot who developed the particulate filter. The catalyst's role is to decrease the level of molecules emitted from the engine block, and the FAP collects the rest. It is therefore essential to have a FAP in good condition if you do not want the Kia Carens 3 to contaminate the air you breathe.
Why the FAP indicator light on your Kia Carens 3
The FAP of your Kia Carens 3 is clogged
Here is the most recurring malfunction. And that's normal, your FAP gets dirty over time. The molecules collect and interfere with the proper circulation of these exhaust gases. A priori, the FAP in the Kia Carens 3 is supposed to be automatically cleaned and therefore make the clusters disappear. That said, if the latter is old you must replace it.
An electronic problem
The concern for the LEDs is that we are not necessarily certain of the malfunction. For example, it sometimes appears that an indicator light is on while the Kia Carens 3 is running smoothly. Your FAP has several electronic sensors that send a signal to your dashboard. If the probes have a malfunction while your FAP is working properly, it is possible that the light may go off.
What to do if the FAP indicator on your Kia Carens 3 lights up?
First of all, it is completely illegal to remove the fap from your vehicle! It is considered an offense. You will need to examine the sounders to see if they are working well. Assuming that these work well, the problem stems from the Particle Filter. If the latter turns out to be dirty, it can be unclogged by driving in the towers for about 10 to 15 minutes. Without exaggerating, it could damage the car. We advise you to drive at 3000 rpm. The temperature of the engine block should in fact carbonize the soot encrusted, and thus clean the FAP. If such a method does not work at all, it will have to be changed.
Conclusion:
The particle filter in poor condition can pollute as well as reduce the power of the vehicle. It is therefore essential to take care of it. Write a comment if our article helped you. Good road !
