The indicator light on your particle filter turns on and you do not know what caused the problem. The particle filter is present especially for vehicles Diesel, even if they are now found for petrol vehicles. Before launching into repairs for the Toyota Land Cruiser Serie 40, it is necessary to know where this concern came from. How does a particle filter work? Why does the indicator light go off? What are the most frequent dysfunctions? In this text, we are going to give a point by point overview. 
What is a FAP used for on your Toyota Land Cruiser Serie 40
As its name suggests, its role is to filter microscopic molecules toxiques of your engine. The molecules are so tiny that they easily enter our body. For your information, it is Peugeot who created this particle filter. The catalyst is used to lower the level of molecules produced by the engine, then the FAP collects the rest. It is therefore essential to have an operational particulate filter in case you no longer want the Toyota Land Cruiser Serie 40 to pollute.
Why the FAP indicator light on your Toyota Land Cruiser Serie 40
The FAP of your Toyota Land Cruiser Serie 40 is clogged
Indeed, this is the most recurrent concern. Indeed, the FAP becomes clogged as time goes by. The molecules collect and block the circulation of these exhaust gases. As a general rule, the FAP on the Toyota Land Cruiser Serie 40 can clean up on its own and therefore eliminate clumps. Unfortunately, if the latter is damaged, it must be changed.
An electronic problem
The concern for the indicator lights is that we are not sure that there is a concern. Indeed, it regularly appears that an indicator light flickers while the Toyota Land Cruiser Serie 40 works without problem. Your FAP has several electronic sounders that send a warning to your dashboard. If your sensors have a problem while your FAP is working properly, it remains likely that the indicator light will turn on.
What to do if the FAP indicator on your Toyota Land Cruiser Serie 40 lights up?
Above all, it is totally forbidden to remove the particle filter on your vehicle! This is punishable by law. You are able to check the sounders to verify that they are working perfectly. Assumed that they themselves work properly, the concern comes from the FAP. If the latter is filthy, it is possible to clean it by driving on over speed for 10 minutes. Without abuse, the process could damage the vehicle. We advise you to drive at 3000 revolutions minutes. The engine heat should burn out the stored soot, and therefore purify the FAP. If ever such a technique really does not work, you will need to replace it.
Conclusion:
The damaged particle filter will pollute but also cause loss of power. It is therefore essential to have it changed. Post a comment if this post was useful to you. See you soon !
