Did you try strapping it to Vcc and GND with some 3-10 K of resistance
to see if that affects the voltage?  Depending on various factors, 1.6V
could very well be what you get for a floating input pin.  And IMO if
you take an input pin, enable pulldown, disable pullup, and don't drive
the pin externally, it should measure pretty darn close to 0V.
