WITH EGR CONTROL VALVE : Removal and Installation

INFOID:0000000005988180

REMOVAL

1.

Remove air duct (inlet) and air cleaner assembly. Refer to 

EM-24, "Exploded View"

.

2.

Drain engine coolant. Refer to 

CO-9, "Draining"

.

CAUTION:

• Perform this step when the engine is cold.
• Never spill engine coolant on drive belt.
NOTE:
This step is not required when removing only intake manifold.

3.

Pull out oil level gauge. 

CAUTION:

Cover the oil level gauge guide openings to avoid entry of foreign materials.

4.

Disconnect water hoses from electric throttle control actuator as follows:
• Attach plug to prevent engine coolant leakage when engine coolant is not drained. Refer to 

CO-9,

"Draining"

.

CAUTION:

Perform this step when the engine is cold.
NOTE:
This step is not required when removing only intake manifold.

5.

Remove electric throttle control actuator.

CAUTION:

• Handle carefully to avoid any shock to electric throttle control actuator.
• Never disassemble electric throttle control actuator.

11. Remove intake manifold.

INSTALLATION

Note the following, and install in the reverse order of removal.

Intake Manifold

1.

Install the gasket to the intake manifold.
NOTE:
Be sure the intake manifold gasket is seated correctly in groove of intake manifold.

2.

Place the intake manifold into the installation position.

3.

5.

Install EGR guide tube.

6.

Install electric throttle control actuator.

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 following;

- HR12DE (TYPE 1): 

EC-105, "Work Procedure"

- HR12DE (TYPE 2): 

EC-378, "Work Procedure"

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

electric throttle control actuator. Refer to following;

- HR12DE (TYPE 1): 

EC-105, "Work Procedure"

 and 

EC-106, "Work Procedure"

- HR12DE (TYPE 2):
