I dont really uunderstand what you mean. Your saying that you put the vacuum pump on the hose to the pressure sensor????
it is most likely the pump. try applying vacuum to someting else. the guage will fall slowly. mine does that

I have a hand vaccum pump with gauge. When I hook it up to the map sensor and then add vaccum, the gauges slowly falls. When I pull the hose off the sensor and add vaccum, the guage holds steady.

hmm
I know that when I do the same to the pressure sensor, the guage will fall slowly...
But then when I would put my thumb over the end of it or something then it will still fall slowly...
sorry I cant help you more. hopefully somebody elso can
However, I don't really think that would mean the sensor is bad.

I've gone to test my map sensor and found that the vaccum drops to 0 in less than a minute. It's not the hose or hand pump. Is this bad or is it supposed to do that?

The amount of air that would be sucked into the intake by this leak is so small as to be totally insignificant. The only thing to worry about is that the output voltages are correct ,

Mine reads a little high. <0.5V high. Can't really tell if that's much of a problem. I'm tempted to put a resisitor on it so it reads in range since it's consistent, just high.
