Welcome to 2CarPros.
Which wire has a voltage drop? Is this while cranking? There are three wires which go to the sensor. Pin 1 is sensor signal, 2 is the ground, three is a 5 volts signal to the sensor. Let me know which one is the issue.
I attached a pic of pin locations so you can tell me which one is the issue. Also, make sure the pins are not damaged, corroded, and there is no damage to them. Finally, you need to go back to the PCM and remove the connector to confirm corrosion there. Since the is power which is lost, chances are it is a connection issue.
Let me know.
