First.......check the temps after a cold soak to make sure it's not a sensor out of range. If the temps are very close when the motor is cold then you have serious issues. Either the oil cooler has replugged or your water pump is having flow issues.

Would be nice if you posted what your truck is. 2003 and early 04's had weak water pumps. always supply as much info as possible.

Do you have any warranty sounds like you may need it, need to have it looked at before the oil cooler pops and you have a real mess.

Compare with ambient temperature and see which sensor is biased/bad. They should be virtually identical. Starting out at a 20* delta definitely indicates one of them is bad. Also, make sure that the scanner you are using is accurate by verifying with another scanner.

The Ford IDS system? Nice!! It should be able to tell you if the sensor is faulty, at least I would think so. You might also try an infared/laser scanner to read temps independantly. Fairly easy to shoot them without removing anything.
