Yes, but not very well. It should throw a CEL because the MAP sensor also reads atmospheric pressure at KOEO. If the PCM sees less than 5.7 PSIA (-9PSIG), as would happen with the sensor unplugged, it will not be happy.

Is the MAP sensor plugged back in? Is the Check Engine Light on? Why was the sensor unplugged? Was just the hose unplugged or the wiring?
