Magnum and Wiring Swap

You know, after thinking about it I think there's something wrong with the wiring to the MAP sensor. The DTC chart just has a generic description for a sensor fault for an OBD I code 14, but OBD II has three, two for high/low voltage and one a sensor fault.
I checked voltage at the connector and it had little over 5 volts on the power side, but it also had just under 5 volts on the signal wire. I bet the power and signal wires are making contact somewhere. I'll get into it and see if I can find it.
