Tercel Sedan 2-Door L4-1456cc 1.5L SOHC (3E-E) (1991)
Cold Start Injector Time Switch: Testing and Inspection
1. Unplug connector from Cold Start Injector Time Switch.
2. Connect a voltmeter to terminal STA on the harness and ground, while an assistant turns the ignition switch to the start position (crank mode).
3. Measure the voltage while the starter is operating.
Voltage:
9.5 - 12.5 volts
4. If no voltage is present, check ignition switch and harness wiring for an open circuit.
5. Using an Ohmmeter, measure the resistance of the Cold Start Injector Time Switch.
Measuring Cold Start Injector Time Switch Resistance
TERMINALS:
RESISTANCE:
STA - STJ
20 - 40 Ohms below 86°F (30°C)
STA - STJ
40 - 60 Ohms above 104°F (40°C)
STA - GROUND
20 - 80 Ohms
6. If not as specified, replace the Cold Start Injector Time Switch.
7. Remove Ohmmeter and reconnect the Time Switch connector.
