Justy Hatchback 4WD L3-1.2L SOHC (MPFI) (1990)
ECU/Crank Angle Sensor Harness Testing
CHECK ECU AND SOLENOID VALVE HARNESS
1. With ignition "OFF," disconnect ECU connector.
2. Measure resistance between ECU connector and solenoid valve connector as follows:
Connector & terminal:
Resistance:
(F119)22-(F7)1
Below 1 Ohm
(F119)22-Ground
Infinite
3. Measure resistance between ECU and ground as follows:
Connector & terminal:
Resistance:
(F119)13-Ground
Below 10 Ohms
(F119)26-Ground
Below 10 Ohms
4. Reconnect ECU and solenoid valve connectors and switch ignition "ON."
5. Measure voltage between ECU connector (F119)22 and ground.
6. At 0.5 second intervals, voltage reading should alternate between less than 2.5V and more than 8V.
