The FAP light comes on and you do not know where the problem is coming from. FAP is present especially for cars Diesel, even if we will see it now for gasoline cars. Before starting any repairs for the Toyota I-unit, it remains essential to understand where this concern came from. What is the role of a particle filter? Why does the light go off? What can be the most regular concerns? In this article, we will cover the subject. warning light-fap-Toyota-I-unit

What is a DPF used on your Toyota I-unit

As its name suggests, it is used to purify microscopic molecules toxiques of the vehicle. The molecules are so small that they easily enter our body. For information, it's Peugeot who made this particle filter. The catalyst is used to reduce the amount of molecules generated from the engine, then the FAP collects the waste. It therefore seems essential to have a working particle filter if you no longer want the Toyota I-unit to pollute the environment.

Why the FAP indicator light on your Toyota I-unit

The FAP of your Toyota I-unit is clogged

This remains the most frequent concern. And that's normal, a FAP gets dirty over time. These molecules form clusters and thus hinder the evacuation of your exhaust gases. Ordinarily, the FAP of the Toyota I-unit must purge itself and thus drive out the clumps. On the other hand, if the latter is old you must change it.

An electronic problem

The concern for these indicator lights is that we are in no way sure that there is a concern. In practice, this often happens that a warning light comes on while the Toyota I-unit is operating properly. This FAP has several electronic sounders that send a message to the dashboard. If the sensors do not work well when the FAP is working perfectly, it is conceivable that your indicator light will go off.

What to do if the FAP indicator on your Toyota I-unit lights up?

To begin with, it is completely prohibited to remove the particle filter on your vehicle! This is an offense. You should examine the sounders to see if they are working properly. If these work properly, the problem comes from the FAP. If it turns out to be dirty, you will be able to clean it by driving in the towers for about 10 to 15 minutes. Do not accelerate too much either, it may damage the engine. We advise you to go up to 3000 rpm. The heat of the vehicle will in fact burn these stored dirt, and thus release your DPF. In case this technique really does not work, it will have to be replaced.

Conclusion:

Your damaged particle filter can pollute as well as decrease acceleration. It is therefore essential to take care of it. Write a comment if this post served you. See you soon !
