Throttle Body Assembly Replacement

REMOVAL PROCEDURE




1. Drain the radiator coolant.
2. Remove the fuel injection sight shield.




3. Remove the IAT (Intake Air Temperature) sensor electrical connector (1) from the IAT sensor (2).




4. Remove the intake air duct from the throttle body.




5. Remove the IAC (Idle Air Control) valve electrical connector from the IAC valve.




6. Remove the TP (Throttle Position) Sensor electrical connector from the TP Sensor.




7. Remove the MAF (Mass Air Flow) sensor electrical connector from the MAF Sensor.




8. Remove the accelerator control cable from the throttle body lever.
9. Remove the cruise control cable from the throttle body lever.
10. Remove the accelerator control cable from the accelerator controls bracket.
11. Remove the cruise control cable from the accelerator controls bracket.
12. Remove the electrical harness retainer clip from the accelerator control cable bracket.




13. Remove the vacuum lines from the throttle body noting location.




14. Remove the throttle body support bracket.




15. Remove the 3 nuts and studs holding the throttle body to the intake manifold.

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.

16. Clean the gasket surface on the intake manifold and the throttle body assembly.

Remove the throttle body assembly from the intake manifold.




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

INSTALLATION PROCEDURE

NOTE: Refer to Fastener Notice in Cautions and Notices.




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

Tighten
Tighten the throttle body retaining nuts and studs to 10 N.m (7 lb ft).

5. Install the throttle body support bracket.

Tighten
Tighten the throttle body support bracket bolts to 11 N.m (8 lb ft).




6. Install the accelerator control cable to accelerator controls bracket at throttle body.
7. Install the cruise control cable to accelerator controls bracket at throttle body.





IMPORTANT: The throttle should operate freely without binding between full closed and wide open throttle.

8. Install the accelerator control to the throttle body lever.
9. Install the cruise control cable to the throttle body lever.
10. Check for complete throttle opening and closing positions by operating the accelerator pedal. Also check for poor carpet fit under the accelerator pedal.
11. Install the electrical harness retainer clip and harness to the accelerator control cable bracket.




12. Install the vacuum lines to throttle body as noted on removal.




13. Install the intake air duct (1) to the throttle body and air cleaner assembly.

Tighten
Tighten the clamp to 2 N.m (18 lb ft).

14. Install the IAT sensor electrical connector to the IAT Sensor.
15. Refill the radiator to replace the lost coolant.
16. Install the fuel injection sight shield.
