Fuel Injector: Inspection: Inspection
- INSPECT FUEL INJECTOR ASSEMBLY
- Measure the resistance between the injector terminals.
Standard resistance
13.4 to 14.2 Ω at 20°C (68 °F)
If the result is not as specified, replace the injector.
- Inspect the injector injection.WARNING:
Keep the injector away from sparks during the test.
- Disconnect the fuel inlet hose (rear fuel pipe) from the fuel main tube.
- Install SST to the fuel main tube.
- SST: 09268-31012
- 90467-13001
- 95336-08070
- 09268-41110
- 09268-41300
- 09268-52011
- SST: 09268-31012
- 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: 09268-31012
- 90467-13001
- 09268-41110
- 09268-41300
- SST: 09268-31012
- Put the injector into the graduated cylinder.WARNING:
Install a suitable vinyl tube onto the injector to contain gasoline spray.
- Operate the fuel pump.
- 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.
Standard injection volume
60 to 73 cm3 (3.7 to 4.5 cu in.) per 15 seconds
Difference between each injector
13 cm3 (0.8 cu in.) or less
- Inspect the fuel leakage.
- In the condition above, disconnect the SST (wire) tester probes from the battery and check the fuel leakage from the injector.
Standard fuel drop
1 drop or less per 12 minutes
- In the condition above, disconnect the SST (wire) tester probes from the battery and check the fuel leakage from the injector.
- Measure the resistance between the injector terminals.
