As a final check I'd connect a standard 0.25w resistor of either 4.7k or 5.6k in place of the sensor. Then if the fault code for the sensor comes back after clearing it, and VIDA still reads 100 degrees C (or some other, clearly erroneous value), then you should conclude that the CCM itself has an internal fault and requires either replacement or board level repair.
Given what you've done so far, and that the replacement sensor's measured resistance is within the expected range, I'm inclined already to suspect CCM failure.
