What is a DPF on your Nissan Maxima 4 for?

As its name presages, its role is to purify microscopic particles toxiques of your engine. These kinds of particles are so tiny that they easily fit through our body. For information, it's Peugeot who invented the particulate filter. Your catalyst has the role of lowering the dose of particles produced by the engine, and the FAP accumulates the surplus. It is therefore essential to have a particle filter in good condition if you do not want the Nissan Maxima 4 to pollute.

Why the FAP indicator light on your Nissan Maxima 4

The FAP of your Nissan Maxima 4 is clogged

Indeed, this is the most common concern. And this is normal, your FAP becomes blocked over time. These particles pile up and thus prevent the flow of exhaust gases. A priori, the FAP in the Nissan Maxima 4 must purge itself and therefore drive out the clumps. However, if it is too old you will have to change it.

An electronic problem

The problem with the LEDs is that we are not sure of the concern. Indeed, it sometimes happens that a warning light comes on while the Nissan Maxima 4 is working perfectly. This FAP has several electronic sensors which transmit a signal towards the dashboard. If the probes have a problem when this FAP is going well, it is possible that the LED will start up.

What to do if the FAP indicator on your Nissan Maxima 4 comes on?

First, it is completely forbidden to remove the particulate filter from your vehicle! Indeed, it is considered a crime. You can check the sensors to see if they work properly. In case these work properly, the concern comes from the Particulate Filter. If it is dirty, you will be able to unclog it by rolling in the towers for about 10 to 15 minutes. Do not climb too much in the towers, the process could damage the car. We advise you to drive to 3000 rpm. The engine temperature will therefore burn out the stored soot, and consequently purify your DPF. When such a procedure is not at all suitable, it should be changed.

Conclusion:

The fap in bad condition should pollute as well as lose power. It is therefore essential to replace it. Leave us a comment if this article was useful to you. See you soon !
