Fuel Injector -- Inspection |
| 1. INSPECT INJECTOR RESISTANCE |
Measure the resistance between the injector terminals.
- Standard resistance:
- 11.6 to 12.4 Ω at 20°C (68°F)
 |
| 2. INSPECT INJECTION VOLUME AND FOR LEAKAGE |
- CAUTION:
- This test involves high-pressure fuel and electricity. Take every precaution 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.
Install the fuel tube connector to SST (hose), then connect the tube connector to the fuel pipe (vehicle side).
- SST
- 09268-41048(90467-13001,09268-41500,95336-08070)
 |
Install the O-ring to the fuel injector.
 |
Connect SST (adapter and hose) to the injector, and hold the injector and union with SST (clamp).
- SST
- 09268-41048(90467-13001,95336-08070,09268-41130)
09268-41400
Put the injector into the graduated cylinder.
- CAUTION:
- Install a suitable vinyl tube onto the injector to contain gasoline spray.
Operate the fuel pump.
Connect the intelligent tester to the DLC3.
Turn the engine switch on (IG).
- NOTICE:
- Do not start the engine.
Push the intelligent tester main switch ON.
Select the following menus: Powertrain / Engine / Active Test / Control the Fuel Pump /Speed.
 |
Connect SST (wire) to the injector and the battery for 15 seconds, and measure the injection volume with the graduated cylinder. Test each injector 2 or 3 times.
- SST
- 09842-30080
- Injection volume:
- 71 to 86 cm3 (4.3 to 5.2 cu.in.) in 15 seconds
- Difference between each injector:
- 15 cm3 (0.9 cu.in.) or less
 |
Check for leakage.
When operating the fuel pump, disconnect the SST (wire) tester probes from the battery and check the fuel leakage from the injector.
- Fuel leakage:
- 1 drop or less in 27 minutes
