Inspection
INSPECTION1. INSPECT INJECTOR INJECTION
CAUTION: Keep injector clean of sparks during the test.
a. Disconnect the fuel inlet hose (fuel tube connector) from the fuel filter.
b. Connect SST (attachment and hose) to the fuel tube.
SST 09268-41047 (09268-52011)
c. Remove the pressure regulator from the delivery pipe.
d. Install the O-ring to the fuel inlet of the pressure regulator.
e. Connect SST (hose) to the fuel inlet of the pressure regulator with SST (union) and the 2 bolts.
SST 09268-41047 (09268-41091)
Torque: 7.5 N.m (80 kgf.cm, 66 in.lbf)
f. Connect the fuel return hose to the fuel outlet of the pressure regulator.
g. Install the O-ring to the injector.
h. Connect SST (adaptor and hose) to the injector, and hold the injector and union with SST (clamp).
SST 09268-41047 (09268-41110, 09268-41300)
i. Put the injector into the graduated cylinder.
CAUTION: Install a suitable vinyl hose onto the injector to prevent gasoline from splashing out.
j. Connect a hand-held tester to the DLC3.
k. Connect the battery negative (-) cable to the battery.
j. Turn the ignition switch ON, and push the hand-held tester main switch ON.
NOTE: Do not start the engine.
m. Select the ACTIVE TEST mode on the hand-held tester.
n. Please refer to the hand-held tester operator's manual for further details.
o. 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 cu.cm (3.4 - 4.2 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 tester 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 min.
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
e. Disconnect the hand-held tester from the DLC3.
f. Reconnect the fuel inlet pipe to the fuel tube.
