Correct. Continuity means zero resistance. 0 ohms. It's really two switches in one housing. It tells the ECU it's either a closed throttle with one switch, or a wide open throttle with the other. In between (throttle part-way open) it should have infinite resistance between the center contact and either of the outside ones. When the throttle is closed, the idle side turns on the idle control valve (through the ECU). If the TPS is bad or adjusted incorrectly, the ICV can't regulate the idle.
