Important: An eight digit part identification number is stamped on the bottom of the throttle body casting. Refer to this number if servicing or part replacement is required.

1. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.



2. Remove the air cleaner outlet resonator. Refer to Air Cleaner Outlet Resonator Replacement .
3. Remove the air cleaner adapter stud.



4. Disconnect the cruise control cable from the throttle body. Refer to Cruise Control Cable Replacement in Cruise Control.



5. Disconnect the accelerator cable from the throttle body. Refer to Accelerator Control Cable Replacement .



6. Remove the nuts retaining the accelerator cable routing bracket.
7. Position the bracket aside.
8. Remove the stud and nuts retaining the accelerator control cable bracket.
9. Position the bracket aside.



10. Disconnect the idle air control (IAC) valve harness connector.



11. Disconnect the throttle position (TP) sensor harness connector.



12. Remove the throttle body retaining studs.



13. Remove the throttle body assembly.
14. Discard the throttle body seal.

Caution: Wear safety glasses in order to avoid eye damage.

1. Clean the seal surface on the intake manifold.



2. Install the throttle body assembly with a new seal.




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.

3. Install the throttle body assembly retaining studs.

Tighten
Tighten the studs to 9 N·m (80 lb in).

4. Install the accelerator control cable bracket using the mounting stud and nuts.

Tighten
Tighten the stud and nuts to 12 N·m (106 lb in).




5. Install the accelerator cable routing bracket using the mounting nuts.

Tighten
Tighten the accelerator cable routing bracket nuts to 9 N·m (80 lb in).





Notice: Check for unrestricted and complete throttle opening and closing positions by operating the accelerator pedal in order to prevent vehicle damage. Also check for poor carpet fit under the accelerator pedal. Throttle should operate freely without bind between full closed and wide open throttle.

6. Install the accelerator cable onto the throttle body. Refer to Accelerator Control Cable Replacement .



7. Install the cruise control cable onto the throttle body. Refer to Cruise Control Cable Replacement in Cruise Control.



8. Connect the TP sensor harness connector.



9. Connect the IAC valve harness connector.



10. Install the air cleaner adapter stud.

Tighten
Tighten the stud to 8 N·m (71 lb in).

11. Install the air cleaner outlet resonator. Refer to Air Cleaner Outlet Resonator Replacement .

Important: The accelerator pedal should operate freely without binding between closed and wide open throttle.

12. Use the following procedure in order to inspect the accelerator pedal operation.

12.1.

Turn ON the ignition, with the engine OFF.

12.2.

Use a scan tool in order to observe the parameter for the TP sensor.

12.3.

Depress the accelerator pedal to the floor.

12.4.

Release the accelerator pedal.

12.5.

Verify the throttle position has gone from 0-100 percent and back to 0  percent.
