Justy Hatchback 2WD L3-1.2L SOHC (MPFI) (1992)
Crank Angle Sensor Testing
CHECK CRANK ANGLE SENSOR
1.
Disconnect connector from distributor.
2.
Measure voltage between distributor side connector terminals while cranking engine:
Connector & terminal:
Voltage: [1]
(F116)1-(F116)2
Varies with rpm
CHECK CYLINDER DISTINCTION SENSOR
1.
Disconnect connector from distributor.
2.
Measure voltage between distributor side connector terminals while cranking engine:
Connector & terminal:
Voltage: [1]
(F116)3-(F116)4
Varies with rpm
[1] Measure with a high impedance voltmeter set below the 0.5V range.
ECU/Crank Angle Sensor Harness Testing
CHECK HARNESS BETWEEN ECU AND DISTRIBUTOR
For crank angle sensor:
1.
Disconnect ECU and distributor connectors.
2.
Check resistance between ECU and distributor connectors and ground as follows:
Connector & terminal:
Resistance:
(F119)3-(F119)1
Below 1 Ohm
(F119)4-(F119)2
Below 1 Ohm
(F119)3-Ground
Infinite
(F119)4-Ground
Infinite
