Do you have the stepper motor plug disconected and butterfly closed or are those the reading with it connected.
When unpluged and the butterfly fully closed with finger it should read per the shop manual 0.50V to 0.54V for the top value and 0.70V to 0.74V for the bottom value. The 0.5V value is adjusted on the right hand TPS and the 0.7V value is adjusted on the left hand TPS. The two TPS's are related so adjusting one can affect the value of the other.
If it moves and it should not, duct tape it, if it does not move and it should WD40 it!
