1.
Remove engine cover (1) with power tool.
2.
Remove air cleaner case and air duct (RH and LH). Refer to
.
3.
Remove electric throttle control actuator as follows:
a.
Drain engine coolant, or when water hoses are disconnected, attach plug to prevent engine coolant leak-
age.
CAUTION:
• Perform this step when engine is cold.
• Do not spill engine coolant on drive belt.
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.
c.
Disconnect harness connector.
d.
Loosen mounting bolts in reverse order as shown in the figure.
NOTE:
• When removing only intake manifold collector, move electric
throttle control actuator without disconnecting the water hose.
• The figure shows the electric throttle control actuator (bank 1)
viewed from the air duct side.
• Viewed from the air duct side, order of loosening mounting
bolts of electric throttle control actuator (bank 2) is the same
as that of the electric throttle control actuator (bank 1).
4.
Disconnect vacuum hose, PCV hose and EVAP hose from intake manifold collector.
5.
Remove EVAP canister purge volume control solenoid valve and EVAP tube assembly from intake mani-
fold collector.

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 and nuts in numerical order as shown in the
figure.
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 (BANK 1 AND BANK 2)
• Tighten in numerical order as shown in the figure.
• Perform the “Throttle Valve Closed Position Learning” when har-
ness connector of electric throttle control actuator is disconnected.
Refer to
EC-18, "THROTTLE VALVE CLOSED POSITION
.
• Perform the “Idle Air Volume Learning” and “Throttle Valve Closed
Position Learning” when electric throttle control actuator is
replaced. Refer to
EC-18, "IDLE AIR VOLUME LEARNING :
and
EC-18, "THROTTLE VALVE CLOSED POSITION
.
NOTE:
• The figure shows the electric throttle control actuator (bank 1)
viewed from the air duct side.
• Viewed from the air duct side, order of loosening mounting bolts of electric throttle control actuator (bank 2)
is the same as that of the electric throttle control actuator (bank 1).
