Removal and Installation

Removal and Installation

Note:

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

REMOVAL

Remove the air duct and resonator assembly. Refer to Exploded View.

Disconnect the harness connector from the electric throttle control actuator.

Remove electric throttle control actuator bolts and reposition.

CAUTION:

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

  • Do not disassemble electric throttle control actuator.

  • Do not reuse electric throttle control actuator gasket.

Remove harness retainer (A) from intake manifold.

(1)

: EGR outlet tube

Disconnect the harness connector (B) from the EVAP canister purge volume control solenoid valve (1).

CAUTION:

Handle carefully to avoid any shock to EVAP canister purge volume control solenoid valve.

Remove the harness retainers (A) from the intake manifold and EVAP canister purge volume control solenoid valve bracket.

Remove the EVAP hose (2) from the EVAP canister purge volume control solenoid valve.

Remove the PCV hose from the intake manifold. Refer to Exploded View.

Remove the EGR volume control valve. Refer to Removal and Installation.

Remove bolts securing radiator hose bracket to intake manifold and reposition radiator hose (upper). Refer to Removal and Installation.

Remove vacuum hose from intake manifold.

Disconnect the harness connector from the manifold absolute pressure (MAP) sensor.

Remove the oil level gauge.

Remove harness retainer (A) from intake manifold.

(1)

: Generator

Remove harness connector (A) from intake manifold (1).

Remove engine harness from vacuum tube and reposition engine harness.

Remove intake manifold with the following procedure: Disconnect the harness connector from the intake manifold runner control valve motor (A) and intake manifold runner control valve position sensor (B).

CAUTION:

  • Handle carefully to avoid any shock to intake manifold runner control valve or intake manifold runner control valve position sensor.

  • Do not remove intake manifold runner control valve motor or intake manifold runner control valve position sensor.

Loosen intake manifold bolts in reverse of the order shown and remove intake manifold.

CAUTION:

  • Cover engine openings to avoid entry of foreign materials.

  • Do not reuse intake manifold gasket.

Note:

Disregard No. 6 when loosening.

Remove bolt and remove manifold absolute pressure (MAP) sensor (if necessary).

CAUTION:

Do not reuse O-ring.

Remove the EVAP canister purge volume control solenoid valve using the following procedure (if necessary): Remove EVAP hose from intake manifold. Remove bolts and remove EVAP canister purge volume control solenoid valve, EVAP canister purge volume control solenoid valve bracket and EVAP hose from intake manifold.

INSTALLATION

Install the intake manifold gasket into the groove of intake manifold.

CAUTION:

Do not reuse intake manifold gasket.

Install the intake manifold using the following procedure: Hand tighten bolts 4 and 5 as shown. Tighten the intake manifold bolts to the specified torque in the sequence shown.

Intake manifold bolts

: 25.0 N·m (2.6 kg-m, 18 ft-lb)

Installation of the remaining components is in the reverse order of removal.

Electric Throttle Control Actuator

  • Tighten electric throttle control actuator bolts to the specified torque diagonally over several steps.

    CAUTION:

    Do not reuse electric throttle control actuator gasket.

    Electric throttle control actuator bolts

    : 10.0 N·m (1.0 kg-m, 89 in-lb)

  • Perform “Throttle Valve Closed Position Learning” after repair when removing harness connector of the electric throttle control actuator. Refer to Work Procedure.
