The FAP warning light goes off and you don't know what the problem is. The FAP mainly exists for cars Diesel, even if we find them now for petrol cars. Before you get into repairs for the Lancia 2000, it remains crucial to know where the concern comes from. How does a particle filter work? Why does the indicator light go off? What can be the most regular dysfunctions? During this file, we will go around the subject. 
What is a FAP used for on your Lancia 2000
As its designation presages, it is used to purify microscopic molecules toxiques of the engine block. These molecules are so small that they can easily enter our body. It is also Peugeot who created the particle filter. The role of the catalyst is to reduce the dose of molecules generated by the vehicle, while the particle filter collects the waste. It is therefore essential to have a FAP in good working order in case you no longer want the Lancia 2000 to contaminate the air you inhale.
Why the FAP indicator light on your Lancia 2000
The FAP of your Lancia 2000 is clogged
Here is the most recurring concern. Don't worry, the particle filter clogs up as time goes by. These molecules collect and block the flow of your exhaust gases. In general, the Lancia 2000 particulate filter can be cleaned on its own and therefore make this waste disappear. However, if it is particularly damaged it will have to be replaced.
An electronic problem
The problem with these LEDs is that we are not necessarily sure of the problem. In fact, it sometimes happens that an indicator light shines while the Lancia 2000 turns without problem. The particulate filter has a few electronic sensors which transmit the warning to the indicator. If these sensors do not work well when your particle filter is doing well, it is plausible that the indicator light turns on.
What to do if the FAP indicator on your Lancia 2000 lights up?
First, it is completely forbidden to remove the particle filter on your Lancia 2000! This is an offense. You can check the probes to see if they work perfectly. If these work perfectly, the problem comes from the FAP. If it is filthy, you can unclog it by driving in towers for 10 to 15 minutes. Do not accelerate too much either, the process can damage the engine. We advise you to drive to 3000 rpm. The temperature of the vehicle can therefore burn this encrusted soot, and thus purify the particulate filter. If such a technique does not work well, you will have to replace it.
Conclusion:
The damaged particle filter can pollute and make you lose power. It is therefore necessary to take care of it. Leave a comment if our article has ever been useful. Good road !
