Fuel Injector (for Port Injection)

2GR-FSE FUEL: FUEL INJECTOR (for Port Injection): INSPECTION

1. INSPECT FUEL INJECTOR ASSEMBLY

(a) Measure the resistance of the injector.





Standard resistance:





(a) If the resistance is not as specified, replace the injector.

(b) Inspect the injection volume.

CAUTION:
This test involves high-pressure fuel and electricity. Take all precautions 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.

(c) Remove the fuel pipe clamp.





(d) Disconnect the fuel tube.





(e) Connect SST to the fuel pipe (the vehicle side).





SST : 09268-31012

09268-41500

90467-13001

95336-08070

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

(g) Install SST and tube to the fuel injector.





SST : 09268-31012

90467-13001

09268-41300

09268-41160

(h) Put the injector into a graduated cylinder.





SST : 09842-30090

CAUTION:
Install a strong rubber tube onto the injector to prevent gasoline from splashing.

(i) Operate the fuel pump (turn the engine switch on (IG)).

(j) 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:

72.3 to 75.2 cm3 (4.4 to 4.6 cu in.) per 15 seconds

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

(k) Check for leakage.

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





Standard fuel drop:

1 drop or less in 24 minutes
