FUEL INJECTOR - INSPECTION
| 1. 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 injector assembly.
| 2. INSPECT INJECTION VOLUME AND LEAKAGE |
Check the injector injection.
- CAUTION:
Assemble SST as shown in the illustration.

| *1 | Lock |
| *2 | SST (Tie Band) |
- NOTICE:
- HINT:
- When removing SST (tie band), disengage the lock.
Check that SST (clamp) and SST (adapter) cannot be easily separated.
Install a vinyl tube to the injector.
Put the injector into a graduated cylinder.
- CAUTION:
- Install a suitable vinyl tube to the injector to contain any gasoline spray.
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
- NOTICE:
- Do not start the engine.
Turn the GTS on.
Enter the following menus: Powertrain / Engine and ECT / Active Test / Activate the Fuel Pump Speed Control.
Connect SST (EFI inspection wire H) to the injector and the battery for 15 seconds and measure the injection volume with a graduated cylinder. Test each injector 2 or 3 times.
- SST
- 09842-30080
- Standard injection volume:
- 71 to 86 cc (4.3 to 5.2 cu. in.) per 15 seconds
- Difference between each injector:
- 15 cc (0.9 cu. in.) or less
| *1 | SST (EFI Inspection Wire H) |
 | Connect |
- NOTICE:
If the result is not as specified, replace the injector assembly.
Check for fuel leakage.
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 every 12 minutes
If the fuel leakage is not as specified, replace the injector assembly.
