Test values
 

anyone out there have the test points and values for a stock Turbo Air Flow Meter?

The test points are pins 1,2,3, and 4. Pin 5 is unused (it isn't even there). Pin 1 is the IAT sensor output, and mine reads about 2.3K ohms @ 74 degrees F (relative to ground, pin 4). Pin 2 is the AFM output signal, and mine reads about 50 ohms when closed, and about 800 ohms, when fully open (also relative to ground, pin 4). Pin 3 is +5 volts in, to the AFM. Pin 4 is ground. There you have it. Hope that helps you out.

Let me add that, since mine is no longer on the car (due to MAF conversion), I really can't provide you with the expected voltage readings, when hooked up and ignition is on. But If my recollection is correct, pin 2 should read somewhere below 0.1 volts, when the door is closed, and somewhere above 4.5 volts, when fully open.
