Injection Inspection

INSPECTION





1. INSPECT INJECTOR INJECTION

CAUTION: Keep injector clear of sparks during the test.





(a) Remove the union bolt and 2 gaskets, and disconnect the fuel inlet hose from the fuel filter outlet.





(b) Connect SST (hose) to the fuel filter outlet with SST (union), the 2 gaskets and union bolt. SST 09268-41047 (90405-09015)

Torque: 29 N.m (300 kgf.cm, 22 ft.lbf)

(c) Install the O-ring to the injector.





(d) Connect SST (hose) to the injector with SST (adapter), and hold the injector and union with SST (clamp). SST 09268-41047 (09268-41110, 09268-41300)
(e) Put the injector into the graduated cylinder.

HINT: Install a suitable vinyl hose 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 TOYOTA hand-held tester main switch ON.

NOTICE: Do not start the engine.

(h) Select the active test mode on the TOYOTA hand-held a tester.
(i) Please refer to the TOYOTA hand-held tester operator's manual for further details.
(j) If you have no 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 09842-30070

Injection volume: 60-73 Cu. Cm (3.7-4.5 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 tester probes of SST (wire) from the battery and check the fuel leakage from the injector. SST 09842-30070

Fuel drop: One 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. SST 09268-41047, 09842-30070
(e) Reconnect the fuel inlet hose to the fuel filter with 2 new gaskets and union bolt.

Torque: 29 N.m (300 kgf.cm, 22 ft.lbf)

(f) Disconnect the TOYOTA hand-held tester from the DLC3.
