- Failure of engine to start

CAUTION: After repair or replacement of faulty parts, conduct CLEAR MEMORY MODE and INSPECTION MODE. Refer to How To Clear Diagnostic trouble Codes.




WIRING DIAGRAM

11AB1: CHECK HARNESS BETWEEN CRANKSHAFT POSITION SENSOR AND ECM CONNECTOR.
1. Turn ignition switch to OFF.
2. Disconnect connector from crankshaft position sensor.

Connector & terminal (E10) No.1 - Engine ground:

3. Measure resistance of harness between crankshaft position sensor connector and engine ground.

CHECK: Is the resistance more than 100 K.Ohm?

YES: 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 (B21).

NO: Go to step 11AB2.

11AB2: CHECK HARNESS BETWEEN CRANKSHAFT POSITION SENSOR AND ECM CONNECTOR.

Connector & terminal (E10) No.1 - Engine ground:

Measure resistance of harness between crankshaft position sensor connector and engine ground.

CHECK: Is the resistance less than 10 ohm?

YES: 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.

NO: Go to step 11AB3.

11AB3: CHECK HARNESS BETWEEN CRANKSHAFT POSITION SENSOR AND ECM CONNECTOR.

Connector & terminal (E10) No.2 - Engine ground.:

Measure resistance of harness between crank- shaft position sensor connector and engine ground.

CHECK: Is the resistance less than 5 ohm?

YES: Go to step 11AB4.

NO: 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 (B21)

11AB4: CHECK CONDITION OF CRANKSHAFT POSITION SENSOR.

CHECK: Is the crankshaft position sensor installation bolt tightened securely?

YES: Go to step 11AB5.

NO: Tighten crankshaft position sensor installation bolt securely.

11AB5: CHECK CRANKSHAFT POSITION SENSOR.
1. Remove crankshaft position sensor.

Terminals No.1 - No.2:

2. Measure resistance between connector terminals of crankshaft position sensor.

CHECK: Is the resistance between 1 and 4 K.Ohm?

YES: Repair poor contact in crankshaft position sensor connector.

NO: Replace crankshaft position sensor.
