If you are toggling the digital pin on and off fast enough, you will pwm the value so that even your multimeter reads a constant voltage. Are you sure you have the program so that the pin stays at a constant state? If you still aren't sure, you could throw an O-scope on it, or put a diode on, anode to the pin, cathode to the top of a small capacitor, bottom of the cap to ground. See if the cap charges to more than the 2v. If it does you are simply toggling the output quickly. It would also help if it was a high-speed diodes, but even if it isn't, it still should charge to more than 2v.
