7. Remove camshaft position sensor (PHASE) from camshaft bracket.
CAUTION:
Handle carefully to avoid dropping and shocks.
Never disassemble.
Never allow metal powder to adhere to magnetic part at sensor tip.
Never place sensor in a location where it is exposed to magnetism.
8. Put the matching mark (A) on the camshaft sprocket (INT) (2)
and the camshaft bracket (1) as shown.
NOTE:
It prevents the knock pin of the camshaft (INT) from engaging
with the incorrect pin hole when installing the camshaft sprocket
(INT).
9. Remove camshaft sprockets (INT) (1) and (EXH) (2).
Secure hexagonal part (A) of camshaft with a wrench. Loosen
camshaft sprocket bolts and remove camshaft sprocket.
CAUTION:
Never rotate crankshaft or camshaft while timing chain
is removed. It causes interference between valve and
piston.
Never loosen the bolts with securing anything other
than the camshaft hexagonal part or with tensioning the
timing chain.
10. Loosen bolts in reverse order as shown.
11. Cut liquid gasket by prying the position ( ) shown, and then
remove the camshaft bracket.
CAUTION:
Be careful not to damage the mating surface.
A more adhesive liquid gasket is applied compared to pre-
vious types when shipped, so it should not be forced off
the position not specified.
12. Remove camshafts.

1. Put V-block on a precise flat table, and support No. 2 and 5 jour-
nal of camshaft.
CAUTION:
Never support No. 1 journal (on the side of camshaft
sprocket) because it has a different diameter from the other
four locations.
2. Set dial indicator (A) vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the
camshaft runout on dial indicator. (Total indicator reading)

INSPECTION AFTER INSTALLATION
The following are procedures for checking fluids leak, lubricates leak.
Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to GI-27, "
Recommended Chemical Products and Sealants".
Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, check again for fuel leakage at connection points.
Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.
Warm up engine thoroughly to make sure there is no leakage of fuel, or any oil/fluids including engine oil and
engine coolant.
Bleed air from lines and hoses of applicable lines, such as in cooling system.
After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
Summary of the inspection items:
* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
Inspection of Camshaft Sprocket (INT) Oil Groove
CAUTION:
Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT-III
and it is directed according to inspection procedure of EC section. Refer to EC-796, "
Diagnosis Pro-
cedure".
Check when engine is cold so as to prevent burns from the splashing engine oil.
1. Check engine oil level. Refer to LU-15, "
Inspection".
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Remove intake manifold. Refer to EM-156, "
Component".
b. Disconnect ignition coil and injector harness connectors.
3. Remove intake valve timing control solenoid valve. Refer to EM-176, "
Component".
