Inspection [08/2015 - ]: Procedure

INSPECT FUEL INJECTOR ASSEMBLY

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.

Inspect the injection volume.

WARNING:

This test involves high-pressure fuel and electricity. Take all precautions regarding safe handling of both the fuel and the electricity. Perform this test in a safe area and avoid any sparks or flames. Do not smoke.

Connect SST to the fuel pipe.

*2	SST (Tie Band)

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.

HINT:

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

Put the injector into a graduated cylinder.
WARNING:
Install a strong rubber tube to the injector to prevent gasoline from splashing.
Operate the fuel pump (Refer to PROCEDURE - Step 1 ).

Connect SST (wire) to the injector and battery for 15 seconds, and then measure the injection volume with the graduated cylinder. Test each injector 2 or 3 times.

SST: 09842-30090

Standard injection volume

82 to 99 cm³ (5.0 to 6.0 cu in.) per 15 seconds

Difference between each injector

17 cm³ (1.0 cu in.) or less

*1	SST (Wire)

If the injection volume is not as specified, replace the injector assembly.

Check for leakage.
1. In the condition above, disconnect the tester probes of SST (wire) from the battery and check for fuel leakage from the injector.
  Standard fuel leakage
  
  1 drop or less in 12 minutes
