Start Injector Time Switch Ignition Switch (ST) STA — STJ STJ STA Start Injection Time Switch Ohmmeter STA/STJ F10095F2076 INSPECTION OF START INJECTOR TIME SWITCH MEASURE RESISTANCE OF START INJECTOR TIME SWITCH (a) Disconnect the connector. (b) Using an ohmmeter, measure the resistance between each terminal. Between terminals | Resistance (Ω) | Coolant temperature STA — STJ | 24 — 40 | below 30°C (86°F) | 40 — 60 | above 40°C (104°F) STA — Ground | 20 — 80 |
