• Perform this inspection as follows after removal, inst
allation, or replacement of the camshaft or any valve-
related parts, or if there are any unusual engine conditions due to changes in valve clearance over time
(starting, idling, and/or noise).
1. Remove the fender protector side cover (RH). Refer to EXT-26, "FENDER PROTECTOR : Removal and
Installation".
2. Remove the rocker cover using power tool. Refer to EM-45, "Removal and Installation"
.
3. Turn crankshaft pulley clockwise when viewed from front to align TDC identification mark (B) with timing indicator (A).
NOTE:
Do not confuse TDC mark (B) with paint marks (C).
4. At this time, check that the both intake and exhaust cam lobes of No. 1 cylinder face outside.
• If they do not face outside, turn crankshaft pulley once more.
5. Measure valve clearances with a feeler gauge at locations marked (X) in the table below.
• No.1 cylinder compression TDC.

c. At the same time, make sure that the mating marks (outer
groove) (B) on camshaft sprockets are lined up with the pink
links (A) in the timing chain, as shown.
• If not, rotate crankshaft pulley one more turn to line up the
mating marks (outer groove) (B) to the pink links (A), as
shown.
10. Remove the timing chain tensioner (primary) with the following procedure.
a. Pull the lever down and release the plunger stopper tab. • Plunger stopper tab can be pushed up to release (coaxial
structure with lever).
b. Insert the stopper pin into the tensioner body hole to hold the lever and keep tab released.
NOTE:
Allen wrench [2.5 mm (0.098)] is used for a stopper pin as an
example.
c. Insert plunger into tensioner body by pressing slack guide.
d. Keep slack the guide pressed and hold it by pushing the stopper
pin through the lever hole and body hole.
e. Remove the bolts and remove the timing chain tensioner (pri- mary).
11. Remove camshaft sprockets with the following procedure. CAUTION:
• Do not rotate the crankshaft or camshaft while the timing chain is removed. It causes interference between valve
and piston.
NOTE:
• Chain tension holding work is not necessary. Timing chain does not fall off the crankshaft sprocket while the front cover is
attached.
a. Line up the mating marks on camshaft sprockets with the pink links in the timing chain, and paint an indelible mating mark on
the sprocket and timing chain link plate.
b. Secure the hexagonal part of camshaft with a suitable tool. Loosen the camshaft sprocket bolts and remove the camshaft sprockets.

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.
