Why the FAP indicator light on your Toyota Corolla 9 Ts
The FAP of your Toyota Corolla 9 Ts is clogged
This is the most common problem. No worries, the particle filter becomes clogged the more time passes. These molecules pile up and hinder the proper circulation of exhaust gases.

An electronic problem
The problem for LEDs is that we are not necessarily sure that there is a problem. Undeniably, it frequently happens that an indicator light goes off while the Toyota Corolla 9 Ts is working properly. Your particle filter has a few electronic sounders that emit a signal to your indicator. When these sensors do not work well while your particle filter is working perfectly, it is conceivable that the indicator will come on.
What to do if the FAP indicator light on your Toyota Corolla 9 Ts lights up?
First of all, it is completely illegal to remove the fap from your vehicle! This is considered an offense. You should check the probes to see if they are working well.

Without abusing it, it could damage the car. We advise you to go up to 3000 rpm. The heat of the vehicle should roast the encrusted soot and purify this particulate filter. If this manipulation really does not work, you will have to replace it with a new one.
