Then with the key on/engine off open and close the throttle and watch that the voltage sweeps up and down consistently.

3 wires. a ground, a 12 volt power, and a signal wire. signal wire should read about 0.5volts throttle closed (idle) and i believe 5 volts wide open throttle. then get back to us.
