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 assembly. Refer to 

EM-25, "Removal and Installation"

.

2. Disconnect water hoses from electric throttle control actuator. 

CAUTION:

• Perform this step when the engine is cold.

• Do not spill engine coolant on 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 harness connector and vacuum hose from EVAP purge control solenoid valve.

CAUTION:

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

5. Disconnect vacuum hose for brake booster from intake manifold.

INTAKE MANIFOLD

6. Remove intake manifold bolts 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.
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.

10. Remove intake manifold support (1) if necessary.

CAUTION:

The intake manifold support functions as a guide for install-

ing the intake manifold.

INSTALLATION

Installation is in the reverse order of removal.

Intake Manifold

1. Install the new 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 gasket.

NOTE:

New gasket for electronically-controlled throttle can be installed

when the electronically-controlled throttle is installed.

2. Place the intake manifold into position.

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 to specification at the rocker

cover. 

Electric Throttle Control Actuator

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

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

tric throttle control actuator. Refer to 

EC-125, "Work Procedure"

.

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

electric throttle control actuator. Refer to 

EC-126, "Work Procedure"
