INTAKE MANIFOLD

Removal and Installation


REMOVAL


WARNING:
To avoid the danger of being scalded, never drain the engine coolant when the engine is hot.
1.Remove engine cover and bracket. Refer to "Exploded View" Exploded View.
2.Remove air cleaner case (upper) and air duct. Refer to "Exploded View" Exploded View.
3.Disconnect manifold absolute pressure (MAP) sensor harness connector.
4.Remove EVAP canister purge control solenoid valve.
5.Disconnect PCV hoses from intake manifold.
- Add matching marks as necessary for easier installation.
6.Drain engine coolant from radiator. Refer to "Draining" Draining Engine Coolant.

CAUTION:
- Perform this step when the engine is cold.
- Never spill engine coolant on drive belts.
NOTE:
When removing only intake manifold, move electric throttle control actuator without disconnecting the water hoses.
7.Remove electric throttle control actuator.





- Loosen mounting bolts in reverse order as shown in the figure.
NOTE:
The figure shows the electric throttle control actuator viewed from the air duct side.

CAUTION:
- Handle carefully to avoid any impact to electric throttle control actuator.
- Never disassemble.
8.Remove intake manifold, using a power tool.





- Loosen mounting bolts in reverse order as shown in the figure.





9.Remove intake manifold gaskets.

CAUTION:
Cover engine openings to avoid entry of foreign materials.
10.Remove manifold absolute pressure (MAP) sensor, if necessary.

CAUTION:
Handle carefully to avoid any impact to manifold absolute pressure (MAP) sensor.

INSTALLATION

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

CAUTION:
Do not reuse O-rings.
Intake Manifold





Tighten in numerical order as shown in the figure.





Electric Throttle Control Actuator





- Tighten in numerical order as shown in the figure.
NOTE:
The figure shows the electric throttle control actuator viewed from the air duct side.
- Perform the "Throttle Valve Closed Position Learning" when harness connector of electric throttle control actuator is disconnected.
Refer to the following table:





- Perform the "Idle Air Volume Learning" and "Throttle Valve Closed Position Learning" when electric throttle control actuator is replaced. Refer to the following table:
