Idle Switch

Unplug idle switch connector. Check continuity between switch and ground. See IDLE SWITCH CONTINUITY  table. See Fig 1 . If switch does not pass test, check harness for open or short circuits. Replace idle switch if necessary. On MX-6 and 626, if idle switch needs replacing, entire throttle body must be replaced.
