Throttle Body Assembly Replacement

REMOVAL PROCEDURE

NOTE: Do Not use solvent of any type when cleaning the gasket surfaces on the intake manifold and the throttle body assembly, as damage to the gasket surfaces and throttle body assembly may result.

Use care in cleaning the gasket surfaces on the intake manifold and the throttle body assembly, as sharp tools may damage the gasket surfaces.




1. Turn OFF the ignition.
2. Remove the fuel injector sight shield.




3. Drain the radiator coolant. Refer to Draining and Filling Cooling System
4. Remove the air cleaner intake duct (3).




5. Disconnect the IAC valve sensor electrical connector (4).
6. Disconnect the TP sensor electrical connector (3).




7. Disconnect the cruise control cable from the throttle body lever.




8. (Graphic shown similar)
Disconnect the accelerator control cable from the throttle body lever.




9. Disconnect the fuel pressure regulator vacuum hose (1).




10. Disconnect the PCV valve hose (1).
11. Disconnect the throttle body vacuum port hose (2).




12. Disconnect the throttle body coolant hoses.
13. Remove the accelerator controls cable bracket, leaving the accelerator and cruse cables connected.
14. Remove the upper nut holding the throttle body to the intake manifold (1).
15. Remove the throttle body assembly (3).
16. Clean the gasket surface on the intake manifold (1) and the throttle body assembly.

INSTALLATION PROCEDURE
