6. Disconnect engine mount control valve solenoid harness connector. Refer to
7. Disconnect VIAS control solenoid valve harness connector. Refer to
EC-27, "VIAS Control Solenoid Valve
8. Disconnect the PCV hose.
9. Disconnect the electric throttle control actuator electrical harness connector.
10. Disconnect the EVAP canister purge volume control solenoid valve hose.
11. Remove the electric throttle control actuator bolts and remove
the electric throttle control actuator and position aside. Loosen-
ing is done in reverse order of torquing.

• Handle carefully to avoid any shock to the electric throttle
control actuator.
• Do not disassemble.
12. Remove the VIAS control solenoid valve as necessary.
13. Remove the EVAP canister purge volume control solenoid valve.
14. Loosen the intake manifold collector bolts and remove the intake
manifold collector and gasket. Loosening is done in reverse
order of torquing.

• Tighten electric throttle control actuator bolts in the order shown.
NOTE:
After installation, re-calibrate the electric throttle control actuator as follows:
1. Perform the
″Throttle Valve Closed Position Learning″ when harness connector of the electric throttle con-
trol actuator is disconnected. Refer to
2. Perform the
″Idle Air Volume Learning″ when the electric throttle control actuator is replaced. Refer to
.
3. Perform the
″Accelerator Pedal Released Position Learning″ when the electric throttle control actuator is

REMOVAL
WARNING:
Do not drain the engine coolant when the engine is hot to avoid the danger of being scalded.
1. Remove the fuel injectors and fuel tube as a unit from the intake manifold. Refer to
.
2. Remove the engine mount control valve solenoid vacuum hose.
3. Remove VIAS control solenoid valve vacuum hoses.
4. Remove the EVAP canister purge volume control solenoid valve vacuum pipes and hoses.
5. Remove the vacuum gallery.
6. Remove the electric throttle control actuator coolant hoses.
7. Remove the intake manifold and gaskets. Loosening is done in
reverse order of torquing.
CAUTION:

INSPECTION AFTER REMOVAL
Surface Distortion
• Using straightedge and feeler gauge, inspect the surface distortion
of the intake manifold. Refer to
.
INSTALLATION
Installation is in the reverse order of removal. Follow the procedure below for specific tightening sequences
and procedures.
CAUTION:
Install the gaskets with the painted surface facing the intake manifold side.
• Install intake manifold studs, (if removed) and tighten to specification.
• Install intake manifold bolts in two steps in the numerical order as
shown.
INSPECTION AFTER INSTALLATION
Make sure there are no fuel leaks at connections as follows:
1. Apply fuel pressure to fuel lines by turning ignition switch ON with engine stopped. Then check for fuel
leaks at connections.
2. Start the engine and rev it up and check for fuel leaks at connections.
WARNING:
Do not touch engine immediately after stopping, as engine is extremely hot.
NOTE:
Use mirrors for checking on connections out of the direct line of sight.
