First, it sounds like the ohms were correct at room temperature. How far did it drop? If you look at the attached pic (pic 1), it shows the range based on temperature.
If the readings seem to parallel what you found, I need you to disconnect the sensor wiring connector. There should be two wires to it, a yellow and a black.
Check the yellow wire for power with the key in the run position. You should see a 5v reference signal to the sensor.
Let me know what you find.
