The light on your DPF is on and you do not know where the problem is coming from. FAP is mainly found in vehicles Diesel, even if we find them today in petrol vehicles. Before you get into repairs in the Jeep Wagoneer, it remains essential to understand what caused this problem. What is the role of a FAP? Why does the light come on? What can be the most regular concerns? In this text, we will go around the question. 
What is an FAP on your Jeep Wagoneer
As its designation suggests, its role is to purify microscopic molecules harmful of your engine block. These kinds of molecules are so small that they easily fit through our body. For your information, it is Peugeot who created this FAP. The catalyst is used to limit the dose of molecules generated by the vehicle, then the particle filter collects the waste. It remains essential to have a particulate filter in good condition if you no longer want the Jeep Wagoneer to pollute the environment.
Why the FAP indicator lights up on your Jeep Wagoneer
The Jeep of your Jeep Wagoneer is clogged
This is the most common problem. Indeed, a particle filter becomes blocked the more time passes. These molecules form clusters and thus hinder the evacuation of exhaust gases. Ordinarily, the particulate filter in the Jeep Wagoneer can clean itself and therefore destroy this soot. That said, if it is particularly damaged it will have to be changed.
An electronic problem
The concern for LEDs is that you are by no means sure of having a problem. In practice, it often happens that a warning light is lit while the Jeep Wagoneer turns without worry. The particle filter has a few electronic sounders that send a message to the dashboard. If the sensors do not work well while this particle filter is working properly, it remains plausible that the indicator light comes on.
What to do if the FAP indicator on your Jeep Wagoneer lights up?
First, it is completely illegal to remove the particulate filter from your vehicle! Indeed, it is punishable by law. You can check the sensors to see if they are working properly. If they ever work properly, the problem comes from the FAP. If it turns out to be dirty, it can be unclogged by driving in the towers for 10 to 15 minutes. Without exaggerating, the process could damage the car. We advise you to drive to 3000 rpm. The heat of the vehicle will in this way carbonize the stored soot, and therefore purify this particulate filter. If such a method does not work at all, you will need to replace it.
Conclusion:
The damaged fap will pollute but also decrease the power of the vehicle. It is therefore important to take care of it. Post a comment in case our article helped you. Good walk !
