2004 Toyota Previa 2.4 petrol

Hi guys, I’m new here. I have a toyota previa and wheni lift the hood I’m trying to locate the mass air flow sensor. This is so can look at it and inspect it for any dirt and debris. I’ve also got. New maxiscan ms409 scan tool and want to test that by disconnecting the sensor and seeing if the scan tool can pick it up. Thanks. B)

The whole bonnet.
