Throttle Body Assembly Replacement VIN K

1. Remove the fuel injection sight shield. Refer to Fuel Injector Sight Shield Replacement in Engine Mechanical.
2. Drain the radiator coolant. Refer to Cooling System Draining and Filling in Engine Cooling.
3. Remove the air cleaner intake duct. Refer to Air Cleaner Inlet Duct Replacement .



4. Disconnect the idle air control (IAC) valve electrical connector from the IAC valve.



5. Disconnect the throttle position (TP) sensor electrical connector from the TP sensor.



6. Disconnect the mass air flow (MAF) sensor electrical connector from the MAF sensor.



7. Remove the cruise control cable (2) from the accelerator control bracket (4) and throttle body lever (3). Refer to Cruise Control Cable Replacement in Cruise Control.



8. Remove the accelerator control cable (2) from the accelerator control bracket and throttle body lever (3). Refer to Accelerator Control Cable Replacement .



9. Remove the electrical harness retainer clip (1) from the accelerator control cable bracket (3) if applicable.



10. Remove the vacuum hoses from the throttle body noting location.



11. Remove the throttle body support bracket.



12. Remove the 3 nuts and studs holding the throttle body to the intake manifold.
13. Remove the throttle body assembly from the intake manifold.

Notice: 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.
14. Clean the gasket surface on the intake manifold and the throttle body assembly.



15. Remove the accelerator controls cable bracket from the throttle body if the throttle body is being replaced.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

1. Install the accelerator controls bracket to the throttle body if necessary.

Tighten
Tighten the accelerator controls bracket bolts to 16 N·m (12 lb ft).




2. Install the new gasket, new inserts and studs if necessary.
3. Install the throttle body assembly.
4. Install the throttle body retaining nuts.

Tighten
Tighten the fasteners to 10 N·m (89 lb in).




5. Install the throttle body support bracket.

Tighten
Tighten the fasteners to 10 N·m  (89 lb in).




6. Install the vacuum hoses to throttle body as noted on removal.



7. Install the electrical harness retainer clip (1) to the accelerator control cable bracket (3) if previously removed.




Important: The throttle should operate freely without binding between full closed and wide open throttle (WOT).

8. Install the accelerator control cable (2) to the accelerator control bracket and throttle body lever (3). Refer to Accelerator Control Cable Replacement .



9. Install the cruise control cable (2) to the accelerator control bracket (4) and throttle body lever (3). Refer to Cruise Control Cable Replacement in Cruise Control.



10. Connect the mass air flow (MAF) sensor electrical connector to the MAF sensor.



11. Connect the throttle position (TP) sensor electrical connector to the TP sensor.



12. Connect the idle air control (IAC) valve electrical connector to the IAC valve.
13. Install the air cleaner intake duct. Refer to Air Cleaner Inlet Duct Replacement .
14. Refill the radiator coolant. Refer to Cooling System Draining and Filling in Engine Cooling.
15. Install the fuel injection sight shield. Refer to Fuel Injector Sight Shield Replacement in Engine Mechanical.
