WARNING:
Check when engine is cold so as to preven t burns from any splashing engine oil.
CAUTION:
Perform this inspection only when DTC P0011, P0014, P052A, P052B is detected in self-diagnostic
results of CONSULT and it is directed according to inspection procedure of EC section. Refer to EC-
210, "Diagnosis Procedure".
1. Check engine oil level and adjust oil level as necessary. Refer to LU-9, "Inspection"
.
2. Remove the intake valve timing intermediate lock control solenoid valve, intake valve timing control sole- noid valve, and exhaust valve timing control solenoid valve. Refer to EM-58, "Intake Valve Timing Interme-
diate Lock Control Solenoid Valve, Intake Valve Timing Control Solenoid Valve, and Exhaust Valve Timing
Control Solenoid Valve".
3. Perform the following procedure to prevent the engi ne from being unintentionally started while checking.
a. Release fuel pressure. Refer to EC-182, "Work Procedure"
.
b. Disconnect injector harness connectors.
4. Crank engine, and then make sure that engine oil comes out of the valve timing control cover oil holes (A). End cranking after
checking.
WARNING:
Be careful not to touch rotating parts (drive belt, crankshaft
pulley, etc.).
CAUTION:
• Engine oil may squirt from intake valve timing intermedi-
ate lock control solenoid valve, intake valve timing control
solenoid valve, exhaust valve timing control solenoid
valve installation holes during cranking. Use a shop cloth
to prevent engine oil from splashing on worker, engine
components and vehicle.
• Do not allow engine oil to get on rubber componen ts such as drive belts or engine mount insula-
tors. Immediately wipe off any splashed engine oil.
5. If engine oil does not come out from valve timing cont rol cover oil holes (A), diagnose problem in lubrica-
tion circuit such as dirty oil groove between oil strainer and intake valve timing intermediate lock control
solenoid valve, intake valve timing control solenoid valve, or exhaust valve timing control solenoid valve.
Refer to LU-7, "Lubrication Circuit"
.
a. Remove components between intake valve timing intermediate lock control solenoid valve, intake valve timing control solenoid valve, exhaust valve timing c ontrol solenoid valve and camshaft sprocket (INT) or
camshaft sprocket (EXH), (if necessary) and then check each oil groove for clogging.
b. Clean oil groove if necessary. Refer to LU-7, "Lubrication Circuit"
.
6. After inspection, install the remaining components in the reverse order of removal.

Inspection after InstallationINFOID:0000000009460570
INSPECTION OF CAMSHAFT SPROCKET (INT) OIL GROOVE
WARNING:
• Check when engine is cold so as to pr event burns from any splashing engine oil.
CAUTION:
• Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT and
it is directed according to inspection procedure of EC section. Refer to EC-716, "Diagnosis Proce-
dure".
1. Check engine oil level. Refer to MA-26, "ENGINE OIL : Inspection"
.
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Release fuel pressure. Refer to FL-5, "Inspection"
.
b. Disconnect ignition coil and injector harness connectors if practical.
3. Remove intake valve timing control solenoid valve.
4. Crank engine, and then make sure that engine oil comes out from intake valve timing control solenoid valve cover oil hole.
End cranking after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
• Engine oil may squirt from intake valve timing control solenoid valve installation hole during cranking. Use a
shop cloth to prevent engi ne oil from splashing on
worker, engine components and vehicle.
• Do not allow engine oil to get on rubber components such
as drive belts or engine mount insulators. I mmediately wipe off any splashed engine oil.
5. Clean oil groove between oil strainer and intake valve timing control solenoid valve if engine oil does not come out from intake valve timing control solenoid valve cover oil hole.
6. Remove components between intake valve timing c ontrol solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
• Clean oil groove if necessary.
7. After inspection, installation of the remaining components is in the reverse order of removal.
