  3. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

    Note

    When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.

  4. REMOVE NO. 1 ENGINE COVER SUB-ASSEMBLY


    1. A01G6L6

      Lift the rear of the No. 1 engine cover sub-assembly to detach it from the 2 pins.

    2. Lift the front of the No. 1 engine cover sub-assembly to detach the it from the pin and remove it.

      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. A01G6TI

      Disconnect the vacuum switching valve assembly from the air cleaner cap sub-assembly.

    2. A01G9UT

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

    3. A01G7KC

      Separate the fuel vapor feed hose from the air cleaner cap sub-assembly.

    4. A01G481

      Disconnect the ventilation hose from the cylinder head cover.

    5. A01G7ME

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

    6. A01G64N

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

  6. DISCONNECT FUEL TUBE SUB-ASSEMBLY

    Note

    Remove any dirt or foreign matter on the fuel tube connector and fuel pipe before performing this work.


    1. A01G6HQE01

      Disengage the claw and remove the No. 1 fuel pipe clamp.

    2. Disconnect the fuel tube sub-assembly from the fuel pipe.

        *a Retainer
        *b O-ring
        *c Fuel Tube Connector
        *d Fuel Pipe
        *e Nylon Tube
        A01G8AH Pinch
        A01G47H Pull

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

        Note

        Be sure to disconnect the fuel tube connector by hand.

      2. If the fuel tube connector and fuel pipe are stuck, push and pull the fuel tube connector to release it. Pull the fuel tube connector off of the fuel pipe carefully.

        Note


        • Be sure to disconnect the fuel tube connector by hand.

        • Do not allow any scratches or foreign matter to get on the parts when disconnecting them as the fuel tube connector has O-rings that seal the fuel pipe.

        • Do not forcibly bend, twist or turn the nylon tube.

      3. Check if there is any foreign matter on the sealing surfaces of the disconnected fuel lines. Clean them if necessary.

      4. Cover the disconnected fuel pipe and fuel tube connector with plastic bags to prevent damage and contamination.

    3. Disengage the clamp to disconnect the fuel tube sub-assembly from the fuel hose clamp.

  7. REMOVE VACUUM SWITCHING VALVE ASSEMBLY (for ACIS)


    1. A01G7OS

      Disconnect the union to vacuum tube hose and wire harness clamp.

    2. Disconnect the 2 vacuum hoses and connector.

    3. Remove the bolt and vacuum switching valve assembly from the intake manifold.

    4. A01G652

      Remove the bolt and vacuum hose clamp.

  8. DISCONNECT WIRE HARNESS

    A01G4J0

    1. Disconnect the 4 fuel injector assembly connectors, throttle body with motor assembly connector and sensor wire connector.

    2. Remove the 2 bolts and separate the 2 wire harness brackets from the intake manifold.

    3. Disengage the clamp to disconnect the wire harness.

  9. REMOVE FUEL DELIVERY PIPE


    1. A01G8C7

      Remove the 2 bolts and fuel delivery pipe with the 4 fuel injector assemblies.

      Note
