The FAP warning light is on and you do not know what caused the malfunction. FAP exists more for cars Diesel, even if we now find them for gasoline cars. Just before starting repairs for this Nissan Leaf, it is necessary to know where this problem comes from. How does a FAP work? Why does the indicator light come on? What are the most frequent dysfunctions? During this file, we will make a point by point topo. warning-fap-Nissan-Leaf

What is a DPF on your Nissan Leaf for?

As its name suggests, its role is to filter out microscopic molecules harmful of the engine block. These molecules are so small that they easily fit into our body. Note that this is Peugeot who created this FAP. Your catalyst has the role of restricting the dose of molecules generated from the engine, and the particle filter collects waste. It is therefore essential to have an operational particle filter if you do not want this Nissan Leaf to pollute.

Why the FAP indicator light on your Nissan Leaf

Your Nissan Leaf's FAP is clogged

It is the most common dysfunction. In fact, a particle filter becomes dirty over time. Molecules collect and thus prevent the circulation of exhaust gases. A priori, the particle filter on this Nissan Leaf will be able to purge itself and expel this soot. However, if it is too damaged, you will have to replace it with a new one.

An electronic problem

The problem with the LEDs is that you are by no means certain to have a malfunction. In fact, it sometimes happens that a warning light flickers while this Nissan Leaf is running carefree. The particle filter holds several electronic sounders which transmit the warning to the dashboard. If the probes ever malfunction while your particle filter is fine, it is plausible that the indicator light comes on.

What to do if the FAP indicator on your Nissan Leaf lights up?

First of all, it's completely prohibited to remove the fap on your Nissan Leaf! This is punishable by law. You can examine the probes to see if they work well. Assuming they work properly, the problem comes from the Particulate Filter. If it was filthy, you can unclog it by rolling in the towers for 10 to 15 minutes. Do not accelerate too much either, the process could damage the vehicle. It is advisable to drive to 3000 revolutions minutes. The temperature of the engine block should thus carbonize the soot encrusted, and thus clean the particle filter. In case this procedure does not work, it will have to be changed.

Conclusion:

A particle filter in poor condition will then pollute but also reduce acceleration. It is therefore important to have it changed. Write a comment in case our article was useful. See you soon !
