INSPECTION




1. INSPECT INJECTOR

CAUTION: Keep injector clear of sparks during the test.




a. Prepare a new fuel tube and remove the fuel tube connector from the pipe.

Part No. 23901-22010




b. Connect SST (hose) and fuel tube connector to the fuel pipe.

SST 09268-41047

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




c. Install the grommet and O ring to the injector.
d. Connect SST (union and hose) to the injector, and hold the injector to prevent gasoline from splashing out.

SST 09268-41047

e. Insert the injector into a graduated cylinder.

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




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

NOTE: Do not start the engine.

h. Select the active test mode on the TOYOTA hand-held tester.
i. Refer to the TOYOTA hand-held tester operator's manual for further details.
j. If you do not have a TOYOTA 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 09842-30080

Volume:47 - 58 cu.cm (2.7 - 3.3 cu in.) per 15 sec.

Difference between each injector: 10 cu.cm (0.6 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 09842-30080

Fuel drop: 1 drop or less per 12 minutes

b. Turn the ignition switch to LOCK.
c. Disconnect the negative (-) terminal cable from the battery.
d. Remove the SST and fuel tube connector.

SST 09268-41047

CAUTION:
- Perform disconnection 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 TOYOTA hand-held tester from the DLC3.
