Injection Inspection

CAUTION: Keep Injector clear of sparks during the test.

1. INSPECT INJECTOR INJECTION
- Disconnect the fuel hose from the fuel filter outlet.



- Connect SST (No.1 union and hose) to the fuel filter outlet with the 2 gaskets and union bolt.
SST 09268-41045 (90405-09015)
HINT: Use the vehicle's fuel filter.
- Remove the fuel pressure regulator.



- Connect the fuel return hose, SST (hose) and SST (No.7 union) to the fuel pressure regulator.
SST 09268-41046 (09268-41091)



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




- Remove the fuse cover on the instrument panel.
- Connect the Toyota hand-held tester to the DLC3.
- Turn the ignition switch ON and Toyota hand-held tester main switch ON.
NOTICE: DO NOT start the engine.

- Select the active test mode on the Toyota hand- held tester.
- Please refer to the Toyota hand-held tester operator's manual for further details.
- If you have no Toyota hand-held tester, connect the positive (+) and negative (-) leads from the battery to the fuel pump connector.



- Connect SST (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: 56 - 69 cm3 (3.4 - 4.2 cu in) per 15 sec.

Difference between each injector: 6 cm3 (0.4 cu in) or less

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

2. INSPECT LEAKAGE



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

Fuel drop: 1 drop or less per minute

- Disconnect the Toyota hand-held tester from the DLC3.
- Turn the ignition switch to LOCK.
- Disconnect the negative (-) terminal cable from the battery.
- Remove SST.
SST 09268-41045
- Reinstall the fuel pressure regulator to the delivery pipe.
Torque: 8 Nm (69 in.lb)
- Reinstall the fuse cover on the instrument panel.
