What should I do if the sensor still remains at the constant 4.56 volts or so?

Get another one, 'cause that one's bit the dust.

All assumes that you know what you're saying when you wrote "so its correct". Maybe have someone look real carefully for solder bridges and other issues?

I sure hope it's fine! Do you think it may be a "dead" one because of the constant voltage it shows?

My suspicion is that you're reading the supply voltage. Particularly because the sensor has a maximum range of 255 inches (2.55 volts). But it's fed with about 5 volts...

Little solder globs can do that sort of thing. As can little 'hairs' of copper wire. and so on.

Thanks. I'll check it out tomorrow
