10AK1CHECK HARNESS BETWEEN CRANK-
SHAFT POSITION SENSOR AND ECM
CONNECTOR.
1) Turn ignition switch to OFF.
2) Disconnect connector from crankshaft position sensor.
3) Measure resistance of harness between crankshaft
position sensor connector and engine ground.
: Connector & terminal
(E10) No. 1—Engine ground:
Is the resistance more than 100 kΩ?
: Repair harness and connector.
NOTE:
In this case, repair the following:
Open circuit in harness between crankshaft position
sensor and ECM connector
Poor contact in ECM connector
Poor contact in coupling connector (B20)
: Go to next.
OBD0718A
: Connector & terminal
(E10) No. 1—Engine ground:
Is the resistance less than 10Ω?
: Repair ground short circuit in harness between
crankshaft position sensor and ECM connector.
NOTE:
The harness between both connectors are shielded.
Repair ground short circuit in harness together with shield.
: Go to next.
OBD0719A
: Connector & terminal
(E10) No. 2—Engine ground:
Is the resistance less than 5Ω?
: Go to step10AK2.
: Repair harness and connector.
NOTE:
In this case, repair the following:
Open circuit in harness between crankshaft position
sensor and ECM connector
Poor contact in ECM connector
Poor contact in coupling connector (B20)
