Engine Coolant Temperature (ECT) sensor 700 1987

Hello all, 1987 760 turbo, I have a problem with fuel getting into the oil. I wanted to test the ECT engine coolant temperature sensor from the ECU computer, but my specs didn't match up with the specs in the FAQ.

For voltage between pins 13 and 5 (ground) I got around 12 volts (DC), which I think was the exact current voltage of the battery. Also for resistance I got infinity between pins 13 and 5. However, testing resistance directly on the sensor's pins, I got something which was probably up to specs. I did make sure to leave the sensor connected and the ignition was ON, but I didn't start the car. Also the connector's connection looked solid and clean. But I do have a general wiring harness problem with a lot of wires under the hood. . . . . I was thinking the sensor's OK but a problem with the wiring maybe?
