Injection/Leakage Inspection

PROCEDURE

Injector Injection Inspection





NOTE: This procedure will require the use of several TOYOTA Special Service Tools or their equivalent.

CAUTION: Keep injector clear of sparks during this test.

1. Disconnect the fuel hose from the fuel filter outlet.





2. Connect union and hose to the fuel filter outlet with 2 new gaskets and the union bolt (SST 09268-41045).
3. Remove the fuel pressure regulator.





4. Connect the fuel return hose, hose and union to the fuel pressure regulator (SST 09268-41045).
5. Install a new 0-ring to the injector.





6. Connect union and hose to the injector and hold the injector and union with the clamp (SST 09268-41045).
7. Put the injector into the graduated cylinder. Install a suitable vinyl hose onto the injector to prevent gasoline from splashing out.





8. Using jumper, connect terminals +B and FP of the Data Link Connector 1 (SST 00843-18020).
9. Reconnect the negative (-) terminal cable to the battery.





10. Turn the ignition switch ON. Do not start the engine.





11. Connect wire to the injector and battery for 15 seconds and measure the injection volume with a graduated cylinder. Test each injector 2 or 3 times (SST 09842-30070).

Volume: 54 - 64 cc (3.3 - 3.9 cu in) per 15 sec.
Difference between each injector: 5 cc (0.3 cu in) or less

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

Injector Leakage Inspection

1. In the condition above. disconnect the test probes of wire from the battery and check the fuel leakage from the injector (SST 09842-30070).

Fuel drop: 1 drop or less per minute

2. Disconnect the negative (-) terminal cable to the battery.

3. Remove jumper and fuel system adaptors (SST 09268-41045 and 09843-18020).

4. Reinstall the fuel pressure regulator to the delivery pipe.

Torque: 8 Nm (69 in lb)

5. Reconnect the negative (-) terminal cable to the battery and inspect for fuel leaks.
