Removal and Installation
REMOVAL
NOTE:
When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.
- Remove air duct (inlet), air duct and air cleaner assembly.
- 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.
- Remove electric throttle control actuator.
CAUTION:
- Handle carefully to avoid any shock to electric throttle control actuator.
- Do not disassemble electric throttle control actuator.
- 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.
- Disconnect vacuum hose for brake booster from intake manifold.
- Remove intake manifold bolts at the rocker cover.
- Loosen bolts in reverse order as shown.
CAUTION:
Cover engine openings to avoid entry of foreign materials.
- Remove intake manifold.
- Remove EVAP purge control solenoid valve from intake manifold if necessary.
CAUTION:
Handle EVAP canister purge volume control solenoid valve carefully and avoid impacts.
- Remove intake manifold support (1) if necessary.
CAUTION:
The intake manifold support functions as a guide for installing the intake manifold.
INSTALLATION
Installation is in the reverse order of removal.
Intake Manifold
- Install the new gasket to the intake manifold.
- Align the protrusions used for checking gasket installation condition with the clearance grooves (A) of the intake manifold groove.
CAUTION:
Do not reuse the gasket.
NOTE:
New gasket for electronicallycontrolled throttle can be installed when the electronicallycontrolled throttle is installed.
- 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.
- Tighten the bolts to specification in the numerical order as shown.
- Tighten the bolts to specification in the numerical order as shown.
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 electric throttle control actuator.
- Perform "Throttle Valve Closed Position Learning" and "Idle Air Volume Learning" after repair when replacing electric throttle control actuator.
