The light on your particle filter lights up and you don't know what the problem is. The particle filter is mainly found on cars Diesel, even if we will see it today on petrol cars. Just before starting repairs on the Toyota Rav 4, it is essential to know what caused the malfunction. How does a FAP work? Why does the light come on? What are the most regular concerns? During this file, we will go around the question. 
What is a FAP used for on your Toyota Rav 4
As its designation suggests, its role is to purify microscopic molecules harmful of your engine block. These particles are so tiny that they easily enter your body. Note that this is Peugeot who invented the FAP. Your catalyst is used to restrict the quantity of molecules emitted by the vehicle, and the particle filter collects the rest. It is therefore essential to have a FAP in good working order in case you do not want the Toyota Rav 4 to pollute the environment.
Why the FAP indicator light on your Toyota Rav 4
The FAP of your Toyota Rav 4 is clogged
Here is the most recurring concern. No worries, the particle filter becomes clogged over time. These molecules pile up and then prevent the flow of these exhaust gases. Generally, the particulate filter in the Toyota Rav 4 can purge itself and therefore destroy this soot. Unfortunately, if the latter is old, you must replace it with a new one.
An electronic problem
The problem with LEDs is that you are not necessarily sure that you have a problem. For example, it sometimes appears that a warning light comes on while the Toyota Rav 4 is running without problems. The particle filter has electronic probes which send a warning in the direction of the indicator. When these probes have a problem while the particle filter works properly, it is possible that your witness will start.
What to do if the FAP indicator light on your Toyota Rav 4 lights up?
First, it is completely illegal to remove the particulate filter from your vehicle! This is an offense. You should check the probes to see if they are working properly. If they themselves function perfectly, the dysfunction comes from the FAP. If it was filthy, you will be able to clean it by driving in the towers for ten minutes. Do not climb too much into the towers, this can damage the car. We advise you to drive to 3000 rpm. The vehicle temperature will in this way be able to roast the encrusted dirt, and thus purify the particulate filter. If this combination does not work, it must be replaced.
Conclusion:
The damaged particle filter will pollute but also reduce the power of the vehicle. It is therefore necessary to deal with it. Post a comment if this text served you well. Good road !
