Your FAP light is on and you don't know what the problem is. The FAP is mainly present on cars Diesel, even if we will see it today on petrol cars. Before attempting repairs on your Toyota Yaris, it is necessary to understand where this problem comes from. How does a particle filter work? Why does the light go off? What can be the most frequent concerns? In this text, we will make a point by point overview. indicator-fap-Toyota-Yaris

What is a FAP used for on your Toyota Yaris

As its designation suggests, it is used to purify microscopic molecules harmful of the vehicle. The molecules are so tiny that they can penetrate our body without difficulty. Note that this is Peugeot who created this particle filter. Your catalyst's role is to lower the dose of molecules generated by the engine block, and the particle filter collects the surplus. It is therefore necessary to have an operational FAP in case you do not want your Toyota Yaris to pollute the environment.

Why the FAP indicator light on your Toyota Yaris

The FAP of your Toyota Yaris is clogged

This is the most usual concern. No worries, the particle filter clogs up over time. The molecules pile up and thus prevent the flow of these exhaust gases. Ordinarily, the particle filter on your Toyota Yaris must be cleaned by itself and make the clumps disappear. On the other hand, if the latter is old, you must replace it with a new one.

An electronic problem

The problem with these indicator lights is that you are not sure of the concern. For example, it sometimes happens that an indicator light goes off while your Toyota Yaris is running without problems. The particulate filter has a few electronic sensors which send a warning to the dashboard. If the depth finders do not pitch well while your particle filter is working properly, it is conceivable that your indicator light will go off.

What to do if the FAP indicator on your Toyota Yaris comes on?

To begin, it is completely prohibited to remove the particle filter on your Toyota Yaris! It is punishable by law. You should check the sensors to see if they work well. If they work properly, the problem is from the FAP. If it was dirty, you can clean it by rolling around the towers for ten minutes. Also do not accelerate too much, the process can damage the car. We advise you to drive at 3000 rpm. The temperature of the engine block will thus be able to burn out this encrusted soot, and thus release the particle filter. If ever such a technique does not work well, it is necessary to have it changed.

Conclusion:

A damaged particle filter can pollute as well as reduce acceleration. It is therefore essential to replace it. Leave a comment if this article served you. Good road !
