To install:


NOTE
Do not loosen the retaining screws for the resin cover of the throttle body assembly. If the screws are loosened, the sensor incorporated in the resin cover becomes misaligned and the throttle body can not work properly.

  1. Align the recess on the intake manifold plenum with the projection of the throttle body gasket. Install the gasket.
    NOTE
    Poor idling etc. may result if the throttle body gasket is not installed properly.

  2.  
  3. Install the throttle body to the engine. Torque the retaining bolts to 18-24 ft. lbs. (24-32 Nm).
  4.  
  5. Continue the installation in the reverse order of the removal procedure.
  6.  
  7. Connect the negative battery cable.
  8.  
  9. On 2005-2006 vehicles, turn the ignition ON and then OFF , and keep it off for at least ten seconds.
  10.  
  11. On 2006 vehicles, complete the vehicle initialization procedure.
    NOTE
    To complete the initialization procedure the following tools are needed. MB991958 scan tool, MB991824 VCI, MB991827 MUT III USB cable, MB991910 MUT III Main harness -A-.

  12.  
  13. Connect the scan tool to the data link connector. To prevent damage to the scan tool be sure that the ignition switch is in the LOCK position before connecting the scan tool.

  21. Initialize the learning value.
  22.  
  23. After initialization complete the idle learning procedure.
    NOTE
    This procedure must be performed when the PCM is replaced, or when the learning value is initialized, as the idling is not stabilized because the learning value in the MFI engine is not completed.

  24.  
  25. Start the engine. Allow the coolant temperature to reach 176 degrees or more.
  26.  
  27. Stop the engine and place the ignition switch in the LOCK position.
