As you all guessed, this had a bad sensor/pcm ground (loose). For the experienced tech, this should have been an easy one. The reason the signals did not go to their extremes is that the grounds were not totally lost and we were still dropping some voltage across them.
If you do not understand why we should be looking for a problem on the ground side of these sensors, please let me know and I’ll try to explain. It is important to also understand that using a scope or DMM, sensor voltage would have gone UP while the temperature went DOWN.
