Your FAP indicator light comes on and you do not know where the malfunction is coming from. The FAP is present mainly for cars Diesel, even if we find them today for petrol cars. Just before starting repairs for your Kia Sephia, it is important to know where the concern comes from. What is the role of a FAP? Why does the light go off? What are the most regular concerns? In this text, we will make a point by point overview. 
What is a FAP used for on your Kia Sephia
As its designation suggests, it is used to filter out microscopic particles harmful of your car. These kinds of molecules are so tiny that they can easily enter our body. Note that this is Peugeot who made the FAP. Your catalyst is used to limit the level of particles emitted by the engine block, then the FAP collects the remains. It is therefore essential to have a FAP in good condition if you no longer want your Kia Sephia to pollute.
Why the FAP indicator lights on your Kia Sephia
The KAP of your Kia Sephia is clogged
This is the most common malfunction. And this is normal, a FAP becomes blocked the more time passes. Particles form clusters and then impede the circulation of your exhaust gases. Generally, the FAP in your Kia Sephia should clean itself and therefore destroy this soot. That said, if this one is particularly old it must be replaced by a new one.
An electronic problem
The problem with these LEDs is that you are not necessarily sure of the malfunction. In fact, it sometimes happens that an indicator light flickers while your Kia Sephia is running without worries. Your FAP has several electronic probes which transmit a signal to the indicator. When your sensors do not work well while this FAP is working perfectly, it is conceivable that the LED will go off.
What to do if the FAP indicator on your Kia Sephia lights up?
Above all, it is completely forbidden to remove the fap on your Kia Sephia! It is punishable by law. You can check the probes to see if they are working properly. If these work properly, the problem comes from the Particulate filter. If the latter is dirty, you will be able to unclog it by driving on a diet for ten minutes. Without exaggerating, this can damage the engine. We advise you to go up to 3000 rpm. The heat from the engine block should roast the stored dirt, thereby purifying the DPF. If ever such a procedure is not suitable at all, you will have to replace it with a new one.
Conclusion:
The damaged fap will pollute but also decrease the power of the vehicle. It remains important to change it. Write a comment if our post was useful. See you soon !
