2. Remove the oil dipstick.
Caution: Cover the dipstick guide hole to prevent foreign material from entering.
3. Disconnect the forced ventilation hose from the intake manifold and rocker cover.
4. Remove the air duct with the resonator assembly (see the relevant section above).
5. Disconnect the vacuum hose from the intake manifold.
6. Disconnect the water hoses from the electric throttle control drive, plug the holes to prevent coolant from leaking.
Attention.
- Perform this step on a cold engine.
- Do not allow coolant to come into contact with drive belts.

7. Remove the electronic throttle control drive.
Caution: Be careful not to hit the electronic throttle control actuator.
8. Remove the intake manifold (1) as follows:
Loosen and remove the intake manifold mounting bolts (A) and (B).
Note: Arrows indicate the front of the engine.
Loosen the mounting bolts from the edges to the middle of the intake manifold.
Caution: Cover engine openings to prevent foreign material from entering.
9. If necessary, remove the brackets from the intake manifold.
10. If necessary, remove the EVAP purge volume control solenoid valve from the intake manifold.
11. Installation is carried out in the reverse order of removal, taking into account the following:
Make sure that the gasket has not fallen out of the installation groove of the intake manifold.
Install the intake manifold and tighten the mounting bolts in the sequence shown in the figure.
Note: The arrow in the figure indicates the front of the engine.
Tighten the intake manifold mounting bolt (A), then tighten the bolt (B).
Note: Arrows indicate the front of the engine.
Tighten the electronic throttle control actuator bolts evenly in a diagonal sequence in several passes.
Perform the closed throttle position learning procedure ("Throttle Valve Closed Position Learning") after repair work, during which the connector of the wires of the electric throttle actuator was disconnected.
Perform the closed throttle position learning procedure ("Throttle Valve Closed Position Learning") and learning the idle air intake volume ("Idle Air Volume Learning") after repair work to replace the electronic throttle control drive.
