If DTC P0011 or P0021 is displayed with DTC P0075 or P0081, first perform the trouble diagnosis for DTC P0075, P0081. Refer to EC-195, "DTC Logic".
DTC CONFIRMATION PROCEDURE
1.
PRECONDITIONINGIf DTC Confirmation Procedure has been previously conducted, always perform the following before conduct-ing 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 between 10 V and 16 V at idle.
>> GO TO 2.
2.
PERFORM DTC CONFIRMATION PROCEDURE-I With CONSULT1. Turn ignition switch ON and select “DATA MONITOR” mode with CONSULT.
2. Start engine and warm it up to the normal operating temperature.
3. Maintain the following conditions for at least 6 consecutive seconds. Hold the accelerator pedal as steady as possible.
CAUTION:
Always drive at a safe speed.
4. Stop vehicle with engine running and let engine idle for 10 seconds.
5. Check 1st trip DTC.
With GST
Follow the procedure “With CONSULT” above.
Is 1st trip DTC detected?
YES >> Proceed to EC-186, "Diagnosis Procedure"
NO >> GO TO 3.

Diagnosis Procedure
INFOID:00000000091357111.
CHECK OIL PRESSURE WARNING LAMP 1. Start engine.2. Check oil pressure warning lamp and confirm it is not illumi-nated.
Is oil pressure warming lamp illuminated?
YES >> Check the engine oil level. Refer to LU-8, "Inspection".
NO >> GO TO 2.
2.
CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVECheck intake valve timing control solenoid valve. Refer to EC-187, "Component Inspection".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Replace malfunctioning intake valve timing control solenoid valve. Refer to EM-52, "Exploded View".
3.
CHECK CRANKSHAFT POSITION SENSOR (POS)Check crankshaft position sensor (POS). Refer to EC-289, "Component Inspection".
Is the inspection result normal?
YES >> GO TO 4.
NO >> Replace crankshaft position sensor (POS). Refer to EM-36, "Exploded View".
4.
CHECK CAMSHAFT POSITION SENSOR (PHASE)Check camshaft position sensor (PHASE). Refer to EC-292, "Component Inspection".
Is the inspection result normal?
YES >> GO TO 5.
NO >> Replace malfunctioning camshaft position sensor (PHASE). Refer to EM-43, "Exploded View".
5.
CHECK CAMSHAFT (INTAKE) Check the following.ENG SPEED 1,400 - 3,175 rpm (A constant rotation is maintained.) COOLAN TEMP/S More than 60°C (140°F)
Selector lever 1st or 2nd position
Driving location uphill
Driving vehicle uphill

• Accumulation of debris on the signal plate of camshaft rear end
• Chipping signal plate of camshaft rear end 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-75,
"Exploded View".
6.
CHECK TIMING CHAIN INSTALLATIONCheck service records for any recent repairs that may cause timing chain misalignment.
Are there any service records that may cause timing chain misalignment?
YES >> Check timing chain installation. Refer to EM-62, "Removal and Installation".
NO >> GO TO 7.
7.
CHECK LUBRICATION CIRCUITCheck lubrication circuit. Refer to EM-80, "Inspection After Removal".
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI-53, "Intermittent Incident".
NO >> Clean lubrication line.
Component Inspection
INFOID:00000000091357121.
CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-I 1. Turn ignition switch OFF.2. Disconnect intake valve timing control solenoid valve harness connector.
3. Check resistance between intake valve timing control solenoid valve terminals as per the following.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Replace malfunctioning intake valve timing control solenoid valve. Refer to EM-52, "Exploded View".
2.
CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II1. Remove intake valve timing control solenoid valve. Refer to EM-52, "Exploded View".
2. Provide 12 V DC between intake valve timing control solenoid valve terminals 1 and 2, and then interrupt it. Check that the plunger moves as shown in the figure.
CAUTION:
Never apply 12 V DC continuously for 5 seconds or more.
Doing so may result in damage to the coil in intake valve timing control solenoid valve.
NOTE:
Always replace O-ring when intake valve timing control solenoid valve is removed.
Is the inspection result normal?
YES >> INSPECTION END
