2. If throttle opener is equipped, connect the handy type vacuum
pump to the throttle opener and apply vacuum þ25.3 kPa
(þ253 mbar, þ190 mmHg, þ7.48 inHg). (If throttle opener is not
equipped, skip this step.)
3. Disconnect the throttle position switch harness connector.
4. Turn ignition switch to ªONº position.
5. Check continuity between terminals 4 and 5 of the closed
throttle position switch.
Continuity should exist.
(If continuity does not exist, check throttle opener and
closed throttle position switch. Then increase vacuum
until closed throttle position switch shows continuity.)
