Idle Switch

Disconnect the ISC servo connector. Check for continuity between terminal No. 3 (1.5L engine) or No. 1 (1.6L engine) and ground. See Fig 1 . With accelerator pedal depressed, no continuity should be present. With accelerator released, continuity should be present. If out of specification, replace ISC servo assembly.
