Installation".
- Remove camshaft position sensors.
- Remove camshaft position sensor bracket.
- Remove the valve timing control cover. Refer to EM-75, "Valve
Timing Control Cover".
- Set the No.1 cylinder at TDC on its compression stroke using
the following procedure:
- Rotate crankshaft pulley clockwise, and align mating mark for
TDC (B) with timing indicator (A) on front cover, as shown.
NOTE:
Do not use the white paint mark (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.
- Remove chain tensioner (1) and timing chain using the following
procedure:
- Pull the lever (B) down and release the plunger stopper tab (C).
- Plunger stopper tab (C) can be pushed up to release (coaxial
structure with lever (B)).
- Insert the stopper pin (A) into the tensioner body hole to hold
the
lever (B) and keep tab released.
NOTE:
Allen wrench [2.5 mm (0.098)] is used for a stopper pin as an
example.
- Insert plunger (C) into tensioner body by pressing timing chain
slack guide (1).
- Keep timing chain slack (1) guide pressed and hold it by pushing
the stopper pin (B) through the lever hole and body hole.
- Remove the chain tensioner bolts (A) and chain tensioner.
- Remove the timing chain from camshaft sprocket (INT) and camshaft
sprocket (EXH).
CAUTION:
- Use suitable tool to prevent timing chain from falling into
front cover after it has been removed
from camshaft sprocket (INT) and camshaft sprocket (EXH).
- Do not rotate the crankshaft or camshafts while the timing
chain is removed. It can cause damage
to the valves and pistons.
- Remove the camshaft sprockets using the following procedure:
- Secure hexagonal part of the camshaft with a suitable tool and
loosen the camshaft sprocket bolt.
- Remove the camshaft sprocket bolt and camshaft sprockets for
both camshafts.

Inspection After Installation
Inspection of Camshaft Sprocket (INT) Oil Groove and Camshaft Sprocket (EXH)
Oil Groove
WARNING: Check when engine is cold so as to prevent 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.
- Check engine oil level and adjust oil level as necessary. Refer to
LU-7, "Inspection".
- Remove the intake valve timing intermediate lock control solenoid
valve, intake valve timing control solenoid
valve, and exhaust valve timing control solenoid valve. Refer to EM-74,
"Intake Valve Timing Intermediate
Lock Control Solenoid Valve, Intake Valve Timing Control Solenoid Valve, and
Exhaust Valve Timing
Control Solenoid Valve".

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:
- If engine oil does not come out from valve timing control cover oil
holes (A), diagnose problem in lubrication
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-5, "Engine Lubrication System".
- Remove components between intake valve timing intermediate lock
control solenoid valve, intake valve
timing control solenoid valve, exhaust valve timing control solenoid valve
and camshaft sprocket (INT) or
camshaft sprocket (EXH), (if necessary) and then check each oil groove for
clogging.
- Clean oil groove if necessary. Refer to LU-5, "Engine Lubrication
System".
- After inspection, install the remaining components in the reverse
order of removal
