2GR-FE FUEL: FUEL INJECTOR: INSPECTION

1. INSPECT FUEL INJECTOR ASSEMBLY

(a) Inspect injector resistance.

(1) Using an ohmmeter, measure the resistance between the terminals.

Resistance:

11.6 to 12.4 Ohms at 20°C (68°F)

If the resistance is not as specified, replace the injector.

(b) Inspect the injection volume.

NOTICE:
* 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.

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





SST : 09268-31012

95336-08070

09268-41500

90467-13001

(2) Install the O-ring to the fuel injector.





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

(4) Put the injector into the graduated cylinder.

CAUTION:
Install a suitable vinyl tube onto the injector to contain gasoline spray.

(5) Operate the fuel pump On-Vehicle Inspection (to 12/2010).

(6) 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

Volume:

84 to 100 cm3 (5.1 to 6.0 cu in.) in 15 seconds

Difference between each injector:

16 cm3 (0.96 cu in.) or less

If the injection volume is not as specified, replace the injector.

(c) Check the leakage.





(1) In the condition above, disconnect the tester probes of SST (wire) from the battery and check the fuel leakage from the injector.

Fuel drop:

1 drop or less in 16 minutes
