Let's move on.

It appears the issue is on the flow sensor cable, please the following:

1. The compartments between the gold tabs on the RJ11 connector is not distorted
2. The sensor head is fully seated onto the flow sensor tube (engine bay side)
3. If all is well, continue...
4. remove the flow sensor assembly from the FAV by ranching from the FAV end so the sensor tube remains intact.
5. Blow gently from the inlet side (female end), let me know if whirling sound is heard.
6. If not, carefully disassembling the flow sensor and examine the internals for debris or clogged filter.
7. If whirling sound is heard, it will be a faulty flow sensor cable (yellow) or controller issue

If at anytime the yellow and red harness was swapped, it would damage the controller and will need factory repair (free)
