Injection/Leakage Inspection

1. INSPECT INJECTOR INJECTION

CAUTION: Keep injector clear of sparks during the test.





a. Purchase the new No.1 fuel pipe and take out the fuel tube connector from its pipe.
Part No.23801-20060





b. Connect SST (hose) and fuel tube connector to the fuel filter outlet.
SST 09268-41047

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

HINT: Use the vehicle fuel filter.





c. Install the grommet and O-Ring to the injector.
d. Connect SST (union and hose) to the injector, and hold the injector and union with SST (clamp).
SST 09268-41047
e. Put the injector into a graduated cylinder.

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





f. Connect the LEXUS hand-held tester to the DLC3.
g. Turn the ignition switch ON and push the LEXUS handheld tester main switch ON.

NOTE: Do not start the engine.

h. Select the ACTIVE TEST mode on the LEXUS hand-held tester.
i. Please refer to the LEXUS hand-held tester operator's manual for further details.

j. If you have no LEXUS hand-held tester, connect the positive (+) and negative (-) leads from the battery to the fuel pump connector.





k. 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: 60 - 73 cu.cm (3.4 - 4.5 Cu in.) per 15 sec.

Difference between each injector: 13 cu.cm (0.8 Cu in.) or less.

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





2. INSPECT LEAKAGE
a. 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 12 minutes

b. Turn the ignition switch OFF
c. Disconnect the negative (-) terminal cable from the battery.
d. Remove the SST and fuel tube connector.
SST 09268-41047, 09842-30070

CAUTION:
^ Perform disconnecting operations of the fuel tube connector (quick type) after observing the precautions.
^ As there is retained pressure in the fuel pipe line, prevent it from splashing inside the engine compartment.

e. Disconnect the LEXUS hand-held tester from the DLC3.
