The indicator light on your particle filter trips and you do not know where the problem is coming from. The particle filter exists mainly on vehicles Diesel, even if they are now found on petrol vehicles. Before launching into repairs on your Toyota Previa 2, it is important to understand where the malfunction is coming from. What is a FAP for? Why does the light go off? What can be the most regular concerns? In this article, we will go over the question. 
What is a FAP used for on your Toyota Previa 2
As its name presages, its role is to filter microscopic molecules harmful of your engine. These kinds of particles are so tiny that they can easily enter your body. For your information, it is Peugeot who developed the FAP. Your catalyst is used to reduce the level of molecules produced from the engine, while the FAP collects waste. It therefore seems essential to have a FAP in good condition in case you no longer want your Toyota Previa 2 to pollute the environment.
Why the FAP indicator light on your Toyota Previa 2
The FAP of your Toyota Previa 2 is clogged
This remains the most common concern. No wonder, your FAP becomes clogged over time. These molecules form clusters then prevent the circulation of these exhaust gases. In principle, the FAP on your Toyota Previa 2 can purge itself and expel this soot. However, if it is too damaged, it will have to be replaced by a new one.
An electronic problem
The problem for LEDs is that you are not necessarily sure you have a problem. In practice, it sometimes appears that an indicator light comes on while your Toyota Previa 2 is operating properly. The FAP has a few electronic sensors that issue the warning to your dashboard. When these probes do not work well while your FAP is working properly, it is possible that the indicator light is on.
What to do if the FAP indicator light on your Toyota Previa 2 lights up?
First, it is completely forbidden to remove the fap from your vehicle! It is an offense. You should check the sounders to see if they are working well. If these work perfectly, the dysfunction comes from the FAP. If the latter is dirty, it is possible to clean it by driving over the speed for about 10 minutes. Without exaggerating, it could damage the car. We advise you to go up to 3000 rpm. The heat of the engine can actually burn the soot encrusted, and therefore purify your DPF. If ever such a technique still does not work, you will have to change it.
Conclusion:
A particle filter in poor condition can pollute but also reduce the power of the vehicle. It is therefore essential to have it changed. Post a comment if our article has ever been useful. Good road !
