Throttle Body Assembly Replacement

THROTTLE BODY ASSEMBLY REPLACEMENT

REMOVAL PROCEDURE

NOTE: Handle the electronic throttle control components carefully. Use cleanliness in order to prevent damage. Do not drop the electronic throttle control components. Do not roughly handle the electronic throttle control components. Do not immerse the electronic throttle control components in cleaning solvents of any type.

IMPORTANT:
- DO NOT for any reason, insert a screwdriver or other small hand tools into the throttle body to hold open the throttle plate, as the wedge inside the throttle body could be damaged.
- An 8-digit part identification number is stamped on the throttle body casting. Refer to this number if servicing, or part replacement is required.




1. Partially drain the cooling system in order to allow the hose at the throttle body to be removed. Refer to Draining and Filling Cooling System in Cooling System.
2. Remove the air cleaner outlet duct.
3. Remove the engine sight shield.
4. Disconnect the throttle actuator motor electrical connector (2).




5. Reposition the coolant air bleed hose clamp at the throttle body.
6. Remove the coolant air bleed hose from the throttle body.




7. Remove the throttle body nuts.
8. Remove the throttle body.




9. Remove and discard the throttle body gasket (1).

INSTALLATION PROCEDURE




1. Install the NEW throttle body gasket (1).




2. Install the throttle body.

NOTE: Refer to Fastener Notice in Service Precautions.

3. Install the throttle body nuts.

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




4. Install the coolant air bleed hose to the throttle body.
5. Position the coolant air bleed hose clamp at the throttle body.




6. Connect the throttle actuator motor electrical connector (2).

IMPORTANT: Verify that the throttle actuator motor harness connector and the connector seal are properly installed and not damaged.

7. Install the engine sight shield.
8. Install the air cleaner outlet duct.
9. Refill the cooling system. Refer to Draining and Filling Cooling System in Cooling System.
10. Connect a scan tool in order to test for proper throttle-opening and throttle-closing range.
11. Operate the accelerator pedal and monitor the throttle angles. The accelerator pedal should operate freely, without binding, between a closed throttle, and a wide open throttle (WOT).
12. Verify that the vehicle meets the following conditions:
- The vehicle is not in a reduced engine power mode.
- The ignition is ON.
- The engine is OFF.
13. Start the engine.
14. Inspect for coolant leaks.
