Idle Switch

WARNING: This page is about a different car, the 2002 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.

Idle switch is mounted on throttle body to monitor closed throttle position. PCM uses this signal to control idle speed. PCM sends signal to Transmission Control Module (TCM) to disengage Torque Converter Clutch (TCC).
