APPARENTLY:
The trouble is NOT the sensor, but WHEN the sensor is read, and the calculation of the number that is displayed.
The sensor is not even read until the car is moving over (some limit) mph. Then, the results are averaged over a LONG time, and many "corrections" are applied, so even the corrected number is not displayed, but a slowly-changing (in slow, like 5 minute, steps) value that apparently works its way from (what was when you last drove?) some wrong value toward a presumably correct value. But, I do not know if I have ever seen it display a "correct" temperature.
We need to complain to Nissan so they can fix the calculation and drastically increase the convergence speed.
