1D-11 Engine Mechanical:
Installation
Reverse removal procedure for installation noting the
following.
• Clean mating surfaces and use new throttle body
gasket (1).
• Use new fuel connector pipe gaskets.
• Tighten fuel connector pipe union bolts and delivery
pipe bolts to specified torque referring to “Fuel System
Components in Section 1G”.
• Use new surge tank pipe gaskets.
• Check to ensure that all removed parts are back in
place.
Reinstall any necessary parts which have not been
reinstalled.
• Refill cooling system referring to “Cooling System
Flush and Refill in Section 1F”.
• Upon completion of installation, verify that there is no
fuel leakage at each connection according to “Fuel
Leakage Check Procedure in Section 1G”.
IMT (Intake Manifold Tuning) Valve Removal and
Installation
S6JB0B1406007
Refer to “Electric Throttle Body Assembly Removal and
Installation”.
IMT (Intake Manifold Tuning) Valve Inspection
S6JB0B1406008
1) Connect special tool (A) to IMT valve (1).
Special tool
(A): 09917–47011
2) Apply vacuum to IMT valve (1) and verify that throttle
(2) fully closes within the specified range. If IMT
valve (1) fails this check, replace it.
CAUTION
!
Do not apply above 88 kPa (0.88 kg/cm
2
, 661
mmHg, 880 mbar) of negative pressure.
Damage may occur to IMT valve (1).
IMT valve operation pressure
1.3 – 34 kPa (0.01 – 0.34 kg/cm
2
, 9.8 – 255 mmHg,
13 – 340 mbar)
3) Let the throttle (2) close for 15 seconds with no
vacuum application and inspect throttle travel. If
throttle travel decreases, replace IMT valve (1).
