Component Inspection

INSPECTION




1. FUEL INJECTOR ASSY
a. Inspect injector resistance.
Using an ohmmeter, measure the resistance between the terminals.

Resistance: 13.4 - 14.2 ohm at 20 °C (68 °F)




b. Inspect injector inspection

CAUTION: Keep injector clear of sparks during the test.

1. Purchase a new fuel tube, and take out the fuel tube connector from its tube.

HINT: Part No. 23901-0D010




2. Connect SST and fuel tube connector to the fuel pipe.

SST 09268-41047 (90467-13001, 95336-08070)

CAUTION: Perform connecting operations of the fuel tube connector (quick type) after observing the precautions.




3. Install an O-ring to the fuel injector.
4. Connect SST (union and hose) to fuel the injector, and hold the fuel injector to prevent gasoline from splashing out.

SST 09268-41047 (90467-13001, 95336-08070,
09268-41110, 09268-41300)




5. Put the fuel injector into a graduated cylinder.

HINT: Install a suitable vinyl tube onto the injector to prevent gasoline from splashing out.

6. Operate the fuel pump.
7. Connect SST to the connector of fuel injector.

SST 09842-30080

8. Connect SST to the battery for 15 seconds, and measure the injection volume with a graduated cylinder. Test the each fuel injector 2 or 3 time.

Injection volume:

1ZZ-FE 60 - 73 cu.cm (3.7 - 4.5 Cu in.) per 15 seconds

2ZZ-GE 77 - 94 cu.cm (4.7 - 5.7 Cu in.) per 15 seconds

Difference between each injector:

1ZZ-FE 13 cu.cm (0.8 cu in.) or less

2ZZ-GE 17 cu.cm (1.0 cu in.) or less




c. Inspect leakage
In the condition above, disconnect the test probes of the SST from the battery, and check the fuel leakage from the fuel injector.

Fuel drop: 1 drop or less per 12 minutes




2. FUEL PUMP
a. Inspect fuel pump resistance.
Using an ohmmeter, measure the resistance between the terminals.

Resistance: 0.2 - 3.0 ohm at 20 °C (68°F)

b. Inspect fuel pump operation
Apply battery voltage to both terminals. Check that the pump operates.

NOTE:
- These tests must be done quickly (within 10 seconds) to prevent the coil from burning out.
- Keep fuel pump as far away from the battery as possible.
- Always do the switching at the battery side.
