Your particle filter light goes off and you do not know what the problem is. The particle filter is mainly found in cars Diesel, even if we will see it now in petrol cars. Just before you start repairs in the Nissan Maxima, it is important to know what is causing this problem. How does a particle filter work? Why does the indicator light go off? What can be the most common concerns? During this file, we will make a point by point topo. 
What is a DPF on your Nissan Maxima for?
As its name suggests, its role is to purify microscopic molecules toxiques of the vehicle. These kinds of particles are so small that they easily fit into your body. It is also Peugeot who invented this particle filter. The catalyst's role is to reduce the quantity of molecules emitted by the vehicle, then the FAP collects the waste. It therefore seems essential to have an operational FAP if you no longer want the Nissan Maxima to pollute the environment.
Why the FAP indicator light on your Nissan Maxima
Your Nissan Maxima's FAP is clogged
This remains the most frequent dysfunction. In fact, your FAP becomes blocked the more time passes. Molecules pile up and thus prevent the circulation of your exhaust gases. As a general rule, the Nissan Maxima's FAP should automatically purge itself and consequently make the clumps disappear. Unfortunately, if it is too old you will have to change it.
An electronic problem
The problem with the LEDs is that you are by no means sure to have a malfunction. Indeed, it regularly happens that a warning light shines while the Nissan Maxima runs without worries. The FAP has a few electronic sensors that send a message to the indicator. If your sounders have a malfunction when this FAP is going well, it is likely that your indicator light is on.
What to do if the FAP indicator light on your Nissan Maxima lights up?
At first, it is completely forbidden to remove the fap on your Nissan Maxima! It is punishable by law. You should check the probes to see if they work perfectly. If they themselves work well, the problem comes from the FAP. If the latter is dirty, it can be cleaned by driving in the towers for about 10 to 15 minutes. Without exaggerating, it could damage the engine. We advise you to go up to 3000 rpm. The heat of the vehicle can therefore burn the stored dirt, and therefore clean your DPF. If such manipulation does not work at all, you will have to replace it with a new one.
Conclusion:
A damaged fap should pollute but also decrease acceleration. It is therefore essential to take care of it. Write a comment if you ever use this text. Good road !
