DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is between 10 V and 16 V at idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE-1
With CONSULT
With GST
Follow the procedure “With CONSULT” above.
Is 1st trip DTC detected? YES >> Proceed to EC-174, "Diagnosis Procedure" NO >> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE-2
With CONSULT
CAUTION:
Always drive at a safe speed.
With GST
Follow the procedure “With CONSULT” above.
Is 1st trip DTC detected? YES >> Proceed to EC-174, "Diagnosis Procedure" NO >> INSPECTION END
Diagnosis Procedure
1.CHECK OIL PRESSURE WARNING LAMP
Is oil pressure warning lamp illuminated? YES >> Check the engine oil level. Refer to LU-7, "Inspection".
NO >> GO TO 2.
2.CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE
Check the exhaust valve timing control solenoid valve. Refer to EC-172, "Component Inspection".
Is the inspection result normal? YES >> GO TO 3.
NO >> Replace exhaust valve timing control solenoid valve. Refer to EM-48, "Exploded View".
3.CHECK CRANKSHAFT POSITION SENSOR (POS)
Check the crankshaft position sensor (POS). Refer to EC-279, "Component Inspection [CKP Sensor (POS)]".
Is the inspection result normal? YES >> GO TO 4.
NO >> Replace crankshaft position sensor (POS). Refer to EM-33, "Exploded View".
4.CHECK EXHAUST VALVE TIMING CONTROL POSITION SENSOR
Check the exhaust valve timing control position sensor. Refer to EC-282, "Component Inspection [CMP Sensor (PHASE)]".
Is the inspection result normal? YES >> GO TO 5.
NO >> Replace exhaust valve timing control position sensor. Refer to EM-48, "Exploded View".
5.CHECK CAMSHAFT (EXH)
Check the following.
Is the inspection result normal? YES >> GO TO 6.
NO >> Remove debris and clean the signal plate of camshaft rear end or replace camshaft. Refer to EM-60, "Removal and Installation".
6.CHECK TIMING CHAIN INSTALLATION
Check service records for any recent repairs that may cause timing chain misaligned.
Are there any service records that may cause timing chain misaligned? YES >> Check timing chain installation. Refer to EM-49, "Removal and Installation".
NO >> GO TO 7.
7.CHECK LUBRICATION CIRCUIT
Refer to LU-7, "Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Clean lubrication line.
Component Inspection
1.CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-1
Is the inspection result normal? YES >> GO TO 2.
NO >> Replace exhaust valve timing control solenoid valve. Refer to EM-48, "Exploded View".
2.CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-2
CAUTION:
Do not apply 12 V DC continuously for 5 seconds or more.
Doing so may result in damage to the coil in exhaust valve timing control solenoid valve.
NOTE:
Always replace O-ring when exhaust valve timing control solenoid valve is removed.
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace exhaust valve timing control solenoid valve. Refer to EM-48, "Exploded View".
