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 PROCEDUREI
If engine does not start, crank engine for at least 2 seconds.
Is 1st trip DTC detected?
YES >> Go to EC, "Diagnosis Procedure".
NO >> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDUREII
Is 1st trip DTC detected?
YES >> Go to EC, "Diagnosis Procedure".
NO >> INSPECTION END
1.CHECK STARTING SYSTEM
Turn ignition switch to START position.
Does the engine turn over? Does the starter motor operate?
YES >> GO TO 2.
NO >> Check starting system.
2.CHECK GROUND CONNECTION
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace ground connection.
3.CHECK INTAKE CAMSHAFT POSITION SENSOR (PHASE) POWER SUPPLY CIRCUIT
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 INTAKE CAMSHAFT POSITION SENSOR GROUND CIRCUIT FOR OPEN AND SHORT
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 INTAKE CAMSHAFT POSITION SENSOR (PHASE) INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Check the continuity between intake
camshaft position 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 INTAKE CAMSHAFT POSITION SENSOR (PHASE)
Refer to EC, "Component Inspection".
Is the inspection result normal?
YES >> GO TO 7.
NO >> Replace intake camshaft position sensor (PHASE). Refer to EM, "Exploded View".
7.CHECK CAMSHAFT (INT)
Check the following.
Is the inspection result normal?
YES >> GO TO 8.
NO >> Remove debris and clean the signal plate of camshaft rear end or replace camshaft. Refer to EM, "Removal and Installation".
8.CHECK INTERMITTENT INCIDENT
Refer to GI, "Intermittent Incident".
>> INSPECTION END
1.CHECK INTAKE CAMSHAFT POSITION SENSORI
Is the inspection result normal?
YES >> GO TO 2.
NO >> Replace intake camshaft position sensor. Refer to EM, "Exploded View".
2.CHECK INTAKE CAMSHAFT POSITION SENSORII
Check resistance intake camshaft position sensor terminals as follows.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace intake camshaft position sensor. Refer to EM, "Exploded View".
