Fuel Injector: Testing and Inspection

2GR-FE FUEL: FUEL INJECTOR: INSPECTION

1. INSPECT FUEL INJECTOR ASSEMBLY

(a) Check the resistance.





(1) Using an ohmmeter, measure the resistance according to the value(s) in the table below.

Standard Resistance:





(2) If the result is not as specified, replace the injector assembly.

(b) Check the operation.

CAUTION:
Perform the inspection in a well-ventilated area.

Do not perform the inspection near a naked flame.

(1) Connect SST (fuel tube connector) to SST (hose), then connect them to the fuel pipe (vehicle side).

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

(4) Set the injector assembly in a graduated cylinder.

CAUTION:
Install a suitable vinyl tube onto the injector assembly to prevent gasoline from spraying.

(5) Operate the fuel pump Testing and Inspection.

(6) Connect SST (wire) to the injector assembly 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

Standard Injection Volume:





Difference between each injector:

16 cm3 (0.98 cu in.) or less

NOTICE:
Always switch the voltage on and off on the battery side, not the injector side.

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

(c) Check for leaks.





(1) Disconnect the tester probes of SST (wire) from the battery and check for fuel leaks from the injector.

Standard fuel drop:

1 drop or less every 16 minutes
