INTAKE MANIFOLD COLLECTOR

1.

Remove engine cover (1) with power tool.

2.

Remove air cleaner case and air duct (RH and LH). Refer to 

EM-25, "Exploded View"

.

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.

• 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

LEARNING : Description"

.

• 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 :

Description"

 and 

EC-18, "THROTTLE VALVE CLOSED POSITION

LEARNING : Description"

.

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)
