Removal Procedure

    Object Number: 1385108 Size: SH
  1. Remove the fuel injector sight shield. Refer to Fuel Injector Sight Shield Replacement in Engine Mechanical - 5.7L.
  2. Loosen the air cleaner outlet duct clamps (1, 2).
  3. Partially remove the air cleaner outlet duct from the air cleaner housing to gain access to the mass air flow/intake air temperature (MAF/IAT) sensor electrical connector.

    4. Object Number: 1385109 Size: SH
  4. Disconnect the MAF/IAT sensor electrical connector (1).
  5. Remove the air cleaner outlet duct assembly.
  6. Remove the MAF/IAT if necessary. Loosen the MAF/IAT clamp (2).

    7. Notice: 

       • Handle the MAF sensor carefully.
       • Do not drop the MAF sensor in order to prevent damage to the MAF sensor.
       • Do not damage the screen located on the air inlet end of the MAF.
       • Do not touch the sensing elements.
       • Do not allow solvents and lubricants to come in contact with the sensing elements.
       • Use a small amount of a soap based solution in order to aid in the installation.

  7. Remove the MAF/IAT sensor from the air cleaner outlet duct. Note the position of the MAF/IAT sensor.
