The FAP light comes on and you don't know where the problem is coming from. FAP exists mainly on cars Diesel, although they will be found more and more on gasoline automobiles. Before attempting repairs on the Citroen Traction 11, it is necessary to know what caused this concern. How does a FAP work? Why does the indicator light go off? What are the most regular concerns? During this file, we will go around the question. 
What is a FAP used for on your Citroen Traction 11
As its name presages, it is used to purify microscopic particles toxiques of the vehicle. The particles are so small that they can easily enter our body. It is also Peugeot who developed this FAP. Your catalyst is used to limit the dose of particles emitted by the engine, while the particle filter collects the rest. It is therefore essential to have an operational FAP if you do not want the Citroen Traction 11 to pollute.
Why the FAP indicator light on your Citroen Traction 11
The FAP of your Citroen Traction 11 is clogged
This is the most common problem. No worries, your particle filter becomes clogged as time goes by. The particles pile up and then hinder the evacuation of your exhaust gases. Usually, the particle filter of the Citroen Traction 11 is supposed to clean itself and therefore expel the clumps. However, if it is too old it must be replaced.
An electronic problem
The problem with these indicator lights is that we are not sure of the problem. Indeed, it often happens that a warning light goes off while the Citroen Traction 11 is running without problem. The particle filter has electronic sensors which transmit the signal to the indicator. When these sounders malfunction while this particle filter works properly, it is conceivable that the indicator light is on.
What to do if the FAP indicator on your Citroen Traction 11 lights up?
First, it is absolutely prohibited to remove the fap on your vehicle! Indeed, it is punishable by law. You should examine the sensors to see if they work perfectly. If these ever work properly, the problem comes from the Particulate filter. If the latter is dirty, it can be cleaned by rolling in the towers for 10 to 15 minutes. Without exaggerating, this could damage the vehicle. We advise you to drive at 3000 rpm. The engine temperature can therefore roast these stored dirt, and purify the particulate filter. When this method is not suitable, it is necessary to have it changed.
