DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at least 10 seconds before conducting the next test.
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-I
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 EC-660, "Diagnosis Procedure".
NO >> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE-II

1. Turn ignition switch OFF.
2. Check ground connection E38. Refer to Ground Inspection in GI-44, "Circuit Inspection".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace ground connection.
3.CHECK CAMSHAFT POSITION (CMP) SENSOR (PHASE) POWER SUPPLY CIRCUIT
1. Disconnect camshaft position (CMP) sensor (PHASE) harness connector.
2. Turn ignition switch ON.
3. Check the voltage between CMP sensor (PHASE) harness connector and ground.
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
4.CHECK CMP SENSOR (PHASE) GROUND CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connectors.
3. Check the continuity between CMP sensor (PHASE) harness connector and ECM harness connector.
4. Also check harness for short to ground and short to power.
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
5.CHECK CMP SENSOR (PHASE) INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Check the continuity between CMP sensor (PHASE) harness connector and ECM harness connector.
2. Also check harness for short to ground and short to power.
Is the inspection result normal? YES >> GO TO 6.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
6.CHECK CAMSHAFT POSITION SENSOR (PHASE)
Refer to EC-662, "Component Inspection".
Is the inspection result normal? YES >> GO TO 7.
NO >> Replace camshaft position sensor (PHASE).
7.CHECK CAMSHAFT (INT)
Check the following.
• Accumulation of debris to the signal plate of camshaft rear end • Chipping signal plate of camshaft rear end
Is the inspection result normal? YES >> GO TO 8.
NO >> Remove debris and clean the signal plate of camshaft rear end or replace camshaft.
8.CHECK CAMSHAFT (EXH)
Check the following.
• Accumulation of debris to the signal plate of camshaft rear end • Chipping signal plate of camshaft rear end
Is the inspection result normal? YES >> GO TO 9.
NO >> Remove debris and clean the signal plate of camshaft rear end or replace camshaft.
9.CHECK INTERMITTENT INCIDENT
Refer to GI-42, "Intermittent Incident".
>> INSPECTION END
Component Inspection
1.CHECK CAMSHAFT POSITION SENSOR (PHASE)-I
1. Turn ignition switch OFF.
2. Loosen the fixing bolt of the sensor.
3. Disconnect camshaft position sensor (PHASE) harness connector.
4. Remove the sensor.
5. Visually check the sensor for chipping.
Is the inspection result normal? YES >> GO TO 2.
NO >> Replace camshaft position sensor (PHASE).
2.CHECK CAMSHAFT POSITION SENSOR (PHASE)-II
Check resistance camshaft position sensor (PHASE) terminals as follows.
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace camshaft position sensor (PHASE).
