Cold Start Injector Time Switch Test
WARNING: This page is about a different car, the 1990 Toyota Land Cruiser and 1989 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
- Unplug cold start injector time switch connector. For cold start injector time switch location, See Figure.
- Using ohmmeter, check resistance between terminals "STA" & "STJ" at appropriate temperature. See Fig 1. See COLD START INJECTOR TIME SWITCH SPECIFICATIONS table. There should be continuity between terminal "STA" and ground. Replace switch if not within specification.
NOTE:
"STA" terminal is fed current from ignition switch during cranking. "STJ" goes to cold start injector.
