Answer
According to my schematic, the air flow sensor is only present on single cam engines.  If you have a dual cam engine, you don't have an air flow sensor.

Also according to the schematic, there are five pins in the air flow sensor connector.  

Since I don't have a car like yours available to look at, I checked the harness routing diagram.  The air flow sensor connector seems to originate in the harness about the same place as the cam sensor connector.  Follow the wiring back from the cam sensor until it joins with wiring from other components, and then follow that wiring to see which one may lead you to the air flow sensor connector.
