      Note

      Attempting to disengage both front and rear pins at the same time may cause the No. 1 engine cover sub-assembly to break.

  5. REMOVE AIR CLEANER CAP SUB-ASSEMBLY


    1. A01HYEI

      Disconnect the vacuum switching valve assembly from the air cleaner hose.

    2. A01HZRG

      Disconnect the mass air flow meter connector and 2 wire harness clamps from the air cleaner cap sub-assembly.

    3. A01HXEG

      Separate the fuel vapor feed hose from the air cleaner hose.

    4. A01HYYJ

      Disconnect the ventilation hose from the cylinder head cover.

    5. A01HYQ8

      Loosen the hose clamp and disconnect the air cleaner hose from the throttle with motor body assembly.

    6. A01HXWR

      Release the 2 clamps and remove the air cleaner cap sub-assembly.

  6. DISCONNECT FUEL TUBE SUB-ASSEMBLY


    1. A01HXMDE01

      Text in Illustration
      *1 Fuel Pipe
      *2 Fuel Tube Connector
      *3 Nylon Tube
      *4 O-ring
      *5 Retainer
      A01I0B8 Pinch
      A01HZQC Pull

      Pinch the retainer of the fuel tube connector, and then pull the fuel tube connector off of the fuel pipe.

      Note


      • Check for foreign matter on the fuel tube around the fuel tube connector. Clean it if necessary. Foreign matter can affect the ability of the O-ring to seal the fuel tube connector and fuel pipe.

      • Do not use any tools to separate the fuel tube connector and fuel pipe.

      • Do not forcefully bend, kink or twist the nylon tube.

      • Keep the fuel tube connector and fuel pipe free from foreign matter.

      • If the fuel tube connector and fuel pipe are stuck, push and pull to release them.

      • Put the fuel tube connector and fuel pipe in plastic bags to prevent damage and contamination.

    3. Remove the fuel tube sub-assembly from the fuel hose clamp.

  7. REMOVE VACUUM SWITCHING VALVE ASSEMBLY (for ACIS)


    1. A01HXV7
