2. Remove engine cover (1) (2) with power tool.
3. Remove air cleaner case and air duct (RH, LH). Refer to EM-15, "
AIR CLEANER AND AIR DUCT" .
4. Remove electric throttle control actuator (bank1, bank2) as follows:
NOTE:
When removing only intake manifold collector, move electric throttle control actuator without disconnect-
ing water hose.
a. Drain engine coolant.
CAUTION:
Perform this step when engine is cold.
b. Disconnect water hoses from electric throttle control actuator. When engine coolant is not drained from
radiator, attach plug to water hoses to prevent engine coolant leakage.
CAUTION:
Do not spill engine coolant on drive belt.
c. Disconnect harness connector.
d. Loosen mounting bolts in reverse order as shown in the figure.
CAUTION:

Handle carefully to avoid any shock to electric throttle
control actuator.

Do not disassemble.
NOTE:

Figure shows electric throttle control actuator (bank1) viewed
from the air duct side.

Viewed from the air duct side, order of loosening mounting
bolts of electric throttle control actuator (bank2) is the same
as that of the electric throttle control actuator (bank1).
5. Disconnect vacuum hose, PCV hose and EVAP hose from intake manifold collector.
6. Remove EVAP canister purge volume control solenoid valve and EVAP tube assembly from intake mani-
fold collector.

7. Loosen mounting bolts with power tool in reverse order as
shown in the figure to remove intake manifold collector.
CAUTION:
Cover engine openings to avoid entry of foreign materials.
8. Remove PCV hose [between intake manifold collector and rocker cover (right bank)].
INSTALLATION
Note the following, and install in the reverse order of removal.
Intake Manifold Collector
If stud bolts were removed, install them and tighten to the specified torque below.

Tighten mounting bolts in numerical order as shown in the fig-
ure.
NOTE:
Tighten mounting bolts to secure gasket and intake manifold col-
lector.
Water Hose

Insert hose by 27 to 32 mm (1.06 to 1.26 in) from connector end.

Clamp hose at location of 3 to 7 mm (0.12 to 0.28 in) from hose end.
Electric Throttle Control Actuator

Install in the reverse order of removal.

Tighten mounting bolts in numerical order as shown in the fig-
ure.
CAUTION:

Handle carefully to avoid any shock to electric throttle
control actuator.

Do not disassemble.

The figure shows the electric throttle control actuator
(bank1) viewed from the air duct side.

Viewed from the air duct side, order of tightening mount-
ing bolts of electric throttle control actuator (bank2) is
the same as that of the electric throttle control actuator
(bank1).

Perform the “Throttle Valve Closed Position Learning” when harness connector of electric throttle control
actuator is disconnected. Refer to EC-77, "
Throttle Valve Closed Position Learning" .

Perform the “Idle Air Volume Learning” and “Throttle Valve Closed Position Learning” when electric throt-
tle control actuator is replaced. Refer to EC-77, "
Idle Air Volume Learning" .
