Default Code 1220

Been chasing this for the past 3 days car is in limp mode. Can someone check to see if they have 12 volts to both sides of the connector on the throttle motor? 2 plug connector on the left side of the throttle body. We have narrowed down to tac module or throttle motor. The repair manual shows the wires but not the voltage. And power to both sides of the plug doesn’t make much sense to me.
