Idle Position Switch
NOTE:
On DOHC engines, idle position switch is a separate switch mounted on throttle body. On other engines, idle position switch is incorporated in idle speed control motor assembly, motor position sensor or throttle position sensor, depending upon vehicle application.
- Disconnect throttle position sensor (TPS) connector. Connect ohmmeter between TPS connector terminals No. 3 and 4 on. See Figure .
- With accelerator pedal pressed, no continuity should be present. With accelerator pedal released, continuity should be present. If idle switch continuity is not as specified, replace TPS.
