No, that senor would not prevent the alternator from charging.
What is the 8th digit of the VIN so I can lookup the wiring diagram?
When using the voltmeter just ground the black test lead to the negative battery post and move only the red lead to test whatever.
If it is the 3.4l engine, check the fuses in this diagram.
It appears to be the same diagram for the 3.8, too.
