REMOVAL

NOTE:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-

ing.
1. Remove air duct (inlet), air duct and air cleaner. Refer to 

EM-26, "Removal and Installation"

.

2. Disconnect water hoses from the electric throttle actuator (if necessary).

CAUTION:

• Perform this step when the engine is cold.

• Do not spill engine coolant on the drive belt.

3. Remove electric throttle control actuator.

CAUTION:

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

• Do not disassemble electric throttle control actuator.

4. Disconnect EVAP purge control solenoid valve harness connector and vacuum hose from EVAP purge

control solenoid valve.

Handle EVAP canister purge volume control solenoid valve carefully and avoid impacts.

5. Disconnect vacuum hose for brake booster from intake manifold.
6. Remove intake manifold bolts (A) at the rocker cover. 

7. Loosen bolts in reverse order as shown.

CAUTION:

Cover engine openings to avoid entry of foreign materials.

8. Remove intake manifold and intake manifold gasket.
9. Remove EVAP purge control solenoid valve from intake manifold (if necessary).

CAUTION:

Handle EVAP canister purge volume control solenoid valve carefully and avoid impacts.

INSTALLATION

Installation is in the reverse order of removal.

Intake Manifold

1. Install the new intake manifold gasket to the intake manifold.

• Align the protrusions used for checking gasket installation con-

dition with the clearance grooves (A) of the intake manifold

groove.

CAUTION:

Do not reuse the intake manifold gasket.

NOTE:

New gasket for electric throttle control actuator can be installed

when the electric throttle control actuator is installed.

2. Place the intake manifold into position.

CAUTION:

Check that the oil level gauge guide is not detached from the securing clip of the water inlet due to

interference of intake manifold.

3. Tighten the bolts to specification in the numerical order as

shown. 

4. Tighten the intake manifold bolts (A) to specification at the

rocker cover. 

Electric Throttle Control Actuator

1. Install electric throttle control actuator gasket to intake manifold.

CAUTION:

Do not reuse electric throttle control actuator gasket.

2. Tighten bolts of electric throttle control actuator equally and diagonally in several steps.

NOTE:

After installation, it is necessary to re-calibrate the electric throttle control actuator as follows:

• Perform “Throttle Valve Closed Position Learning” after repair when removing harness connector of the elec-

tric throttle control actuator. Refer to 

EC-127, "Work Procedure"

.

• Perform “Throttle Valve Closed Position Learning” and “Idle Air Volume Learning” after repair when replacing

electric throttle control actuator. Refer to 

EC-127, "Work Procedure"

.
