Jerry,
Glad I could help you find the problem.. After posting my responce above, I got to thinking about where the sensor is mounted..... if other than in the pan. My thinking was that maybe the sensor is not grounded!!!! If you haven't already pulled the sensor, you might take a short length of wire and hook one end to the engine block and the other to the body (threaded part) of the sensor, and see what happens.
