DTC CONFIRMATION PROCEDURE


1. PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
1.Turn ignition switch OFF and wait at least 10 seconds.
2.Turn ignition switch ON.
3.Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:

Before performing the following procedure, confirm that battery voltage is more than 10.5 V with ignition switch ON.
- GO TO 2.

2. PERFORM DTC CONFIRMATION PROCEDURE

1.Start engine and let it idle for at least 5 seconds.
If engine does not start, crank engine for at least 2 seconds.
2.Check 1st trip DTC.
Is 1st trip DTC detected?
YES- Go to "Diagnosis Procedure" .
NO- INSPECTION END


Diagnosis Procedure


1. CHECK GROUND CONNECTION

1.Turn ignition switch OFF.
2.Check ground connection E15. Refer to Ground Inspection in "Circuit Inspection" Circuit Inspection.
Is the inspection result normal?
YES- GO TO 2.
NO- Repair or replace ground connection.

2. CHECK CRANKSHAFT POSITION (CKP) SENSOR (POS) POWER SUPPLY CIRCUIT-I

1.Disconnect crankshaft position (CKP) sensor (POS) harness connector.
2.Turn ignition switch ON.
3.Check the voltage between CKP sensor (POS) harness connector and ground.





Is the inspection result normal?
YES- GO TO 6.
NO- GO TO 3.

3. CHECK CRANKSHAFT POSITION (CKP) SENSOR (POS) POWER SUPPLY CIRCUIT-II

1.Turn ignition switch OFF.
2.Disconnect ECM harness connector.
3.Check the continuity between CKP sensor (POS) harness connector and ECM harness connector.





Is the inspection result normal?
YES- GO TO 4.
NO- Repair open circuit.

4. CHECK SENSOR POWER SUPPLY CIRCUIT

Check harness for short to power and short to ground, between the following terminals.





Is the inspection result normal?
YES- GO TO 5.
NO- Repair short to ground or short to power in harness or connectors.

5. CHECK COMPONENTS

Check the following.
- Refrigerant pressure sensor (Refer to "Component Function Check" Refrigerant Pressure Sensor).
- Accelerator pedal position sensor (Refer to "Component Inspection" P2122).

YES- GO TO 10.
NO- Replace refrigerant pressure sensor. Refer to "Removal and Installation" Removal and Installation.

6. CHECK CKP SENSOR (POS) GROUND CIRCUIT FOR OPEN AND SHORT

1.Turn ignition switch OFF.
2.Check the continuity between CKP sensor (POS) harness connector and ECM harness connector.





3.Also check harness for short to ground and short to power.
Is the inspection result normal?
YES- GO TO 7.
NO- Repair open circuit or short to ground or short to power in harness or connectors.

7. CHECK CKP SENSOR (POS) INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1.Disconnect ECM harness connector.
2.Check the continuity between CKP sensor (POS) harness connector and ECM harness connector.





3.Also check harness for short to ground and short to power.
Is the inspection result normal?
YES- GO TO 8.
NO- Repair open circuit or short to ground or short to power in harness or connectors.

8. CHECK CRANKSHAFT POSITION SENSOR (POS)

Refer to "Component Inspection" .
Is the inspection result normal?
YES- GO TO 9.
NO- Replace crankshaft position sensor (POS). Refer to "Exploded View" Exploded View.

9. CHECK GEAR TOOTH

Visually check for chipping signal plate gear tooth.
Is the inspection result normal?
YES- GO TO 10.
NO- Replace the signal plate. Refer to "Exploded View" Exploded View.

10. CHECK INTERMITTENT INCIDENT

Refer to "Intermittent Incident" Intermittent Incident.
- INSPECTION END


Component Inspection
