The particle filter indicator light turns on and you do not know what caused the problem. The particle filter is mainly found in vehicles Diesel, although they will now be found in petrol vehicles. Before starting any repairs in the Toyota Highlander 2, it is wiser to know where the problem comes from. What is the role of a particle filter? Why is the indicator light on? What can be the most frequent concerns? In this text, we will go around the subject. 
What is a FAP used for on your Toyota Highlander 2
As its designation indicates, it is used to filter microscopic molecules toxiques of the engine block. The molecules are so small that they easily fit through our body. For information, it's Peugeot who developed the particulate filter. Your catalyst has the role of restricting the quantity of molecules emitted from the engine, and the particle filter collects the surplus. It is therefore capital to have a FAP in good working condition if you do not want the Toyota Highlander 2 to contaminate the air you inhale.
Why the FAP indicator light on your Toyota Highlander 2
The FAP of your Toyota Highlander 2 is clogged
This remains the most usual concern. No wonder, a particle filter clogs over time. The molecules collect and hinder the evacuation of these exhaust gases. Ordinarily, the particulate filter on the Toyota Highlander 2 should clean itself and dispose of this waste. That said, if the latter is damaged it will have to be changed.
An electronic problem
The problem with these LEDs is that you can never be sure that there is a problem. Indeed, it happens when a warning light is lit while the Toyota Highlander 2 is turning properly. This particle filter has electronic probes which send a warning to the indicator. When your sensors have a problem while the particulate filter is working perfectly, it is plausible that your indicator light turns on.
What to do if the FAP indicator light on your Toyota Highlander 2 lights up?
First, it is absolutely illegal to remove the fap on your Toyota Highlander 2! Indeed, it is considered a crime. You will need to check the probes to see if they work perfectly. If these work properly, the problem comes from the FAP. If it was dirty, you can clean it by driving on a diet for 10 minutes. Do not climb too much in the towers, this could damage the engine. We advise you to drive to 3000 rpm. The heat of the engine block will thus be able to grill these encrusted dirt, and thus purify your particulate filter. In case this method is not suitable, it will have to be changed.
Conclusion:
The damaged fap can pollute but also cause loss of power. It is therefore important to take care of it. Post a comment if this text was useful. Enjoy the road!
