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 INJECTION VOLUME AND LEAKAGE

Check the injector injection.

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 or flame.
Do not smoke.

Discharge the fuel system pressure.

Install a new O-ring to the fuel injector assembly.

Connect SST (adapter and hose) to the fuel injector assembly, and hold the fuel injector assembly and adapter with SST (clamp).

SST

09268-31014 ( 09268-41141, 09268-41410, 09268-41700, 95336-08070 )
*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.
Check that SST (clamp) and SST (adapter) cannot be easily separated.
Put the fuel injector assembly into a graduated cylinder.

CAUTION:

Install a suitable vinyl tube to the fuel injector assembly to contain any gasoline spray.
Connect the GTS to the DLC3.
Turn the ignition switch to ON.

Note

Do not start the engine.
Turn the GTS on.
Enter the following menus: Powertrain / Engine / Active Test / Control the Fuel Pump Speed / ON.

Powertrain > Engine > Active Test

*a SST (Wire)

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

SST

09842-30080

Standard injection volume

71 to 85 cc (4.3 to 5.2 cu.in.) per 15 seconds

Difference between each injector

14 cc (0.9 cu. in.) or less

Note

Always turn the voltage on and off on the battery side, not the fuel injector assembly side.

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

Check for fuel leakage.
1. In the condition above, disconnect the tester probes of SST (wire) from the battery and check for fuel leakage from each fuel injector assembly.
  
  Standard
  
  1 drop or less per 17 minutes
  
  If the leakage is not as specified, replace the fuel injector assembly.
