Your FAP indicator light goes off and you don't know where the problem is coming from. FAP is more present on cars Diesel, even if we will see it today on petrol cars. Before attempting repairs on this Lancia Delta, it is wiser to understand where the malfunction is coming from. How does a FAP work? Why does the indicator light come on? What are the most regular concerns? In this article, we will cover the subject. 
What is a FAP for on your Lancia Delta
As its designation indicates, it is used to filter microscopic particles harmful of your engine block. These particles are so tiny that they fit easily through your body. Note that this is Peugeot who created the FAP. Your catalyst has the role of reducing the quantity of particles generated by the engine, while the particle filter collects the waste. It therefore seems essential to have an operational particle filter if you no longer want this Lancia Delta to pollute the environment.
Why the FAP indicator light on your Lancia Delta
The FAP of your Lancia Delta is clogged
This remains the most usual concern. In fact, the particle filter becomes dirty the more time passes. These particles pile up and then hinder the flow of these exhaust gases. In general, the particle filter in this Lancia Delta is supposed to clean itself and thus eliminate this waste. However, if it is particularly damaged you will have to replace it.
An electronic problem
The concern for sighted people is that we are not necessarily certain of the concern. In practice, it sometimes happens that an indicator light goes off while this Lancia Delta is turning properly. Your particle filter has electronic sensors which send the warning to the dashboard. If the sounders ever malfunction while your particle filter is fine, it is likely that the indicator light will go off.
What to do if the FAP light on your Lancia Delta lights up?
Above all, it is absolutely prohibited to remove the particulate filter on your vehicle! Indeed, it is considered a crime. You can check the sensors to see if they are working properly. If these function perfectly, the malfunction comes from the FAP. If the latter was dirty, it is possible to clean it by driving on a diet for about 10 to 15 minutes. Do not climb too much in the towers, the process may damage the vehicle. We advise you to go up to 3000 rpm. The heat from the engine should therefore burn the encrusted dirt, and release this particulate filter. In the event that such manipulation does not work, it will have to be changed.
Conclusion:
A damaged fap will pollute as well as reduce acceleration. It is therefore essential to have it changed. Leave us a comment if our post was useful. Enjoy the road!
