PROCEDURE


  1. INSPECT FUEL INJECTOR ASSEMBLY


    1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 11.6 to 12.4 Ω

      If the result is not as specified, replace the fuel injector assembly.

  2. INSPECT INJECTION VOLUME AND LEAKAGE


    1. Check the injection volume.

      CAUTION:


      • This test involves high-pressure fuel and electricity.

      • Take every precaution regarding safe handling of both the fuel and the electrical parts.

      • Perform this test in a safe area and avoid any sparks and flames.

      • Do not smoke.

      6. A01LDK9C01
        *1 Fuel Pressure Regulator Assembly
        *a SST (Hose Band)
        *b SST (Hose)
        *c SST (Union No. 7)

        Connect SST to the fuel pressure regulator assembly with the 2 bolts.

        SST
        09268-31014   ( 09268-41091, 09268-41700, 95336-08070 )
        Torque:
        9.0 N*m  { 92 kgf*cm, 80 in.*lbf }

      7. Install the O-ring to the fuel injector assembly.

      8. A01L8Q3C01
        *a SST (Hose Band)
        *b SST (Adaptor)
        *c SST (Hose)
        *d SST (Clamp)
        *e Vinyl Tube

        Assemble SST as shown in the illustration.

        SST
        09268-31014   ( 09268-41300, 09268-41600, 09268-41700, 95336-08070 )

        Note

        Make sure that SST (adapter) and SST (clamp) are not loose and do not rattle.

      9. A01LCVBC01
        *a SST (Tie Band)
        *b Lock

        Pass SST (tie band) through the loop on the handle of SST (clamp) to secure SST (clamp) to SST (adapter).

        SST
        09268-31014   ( 09268-41800 )

        Note


        • As SST (tie band) does not completely prevent SST (clamp) from becoming loose, do not subject the parts to any impacts while using them.

        • Before using SST (tie band), make sure that there is no deterioration, damage or cracks. If there are any abnormalities, replace SST.

        Tech Tips

        When removing SST (tie band), disengage the lock.

      10. Check that SST (clamp) and SST (adapter) cannot be easily separated.

      11. Install a vinyl tube to the fuel injector assembly.

      12. Put the fuel injector assembly into a graduated cylinder.

        Note

        Install a suitable vinyl tube to the fuel injector assembly to contain any gasoline spray.

      13. Operate the fuel pump.

        *a SST (EFI Inspection Wire H)
        B0027PX Connect

        Connect SST (EFI inspection wire H) to the fuel injector assembly and the battery for 15 seconds, and measure the injection volume with a graduated cylinder. Test each fuel injector assembly 2 or 3 times.

        SST
