Off-Vehicle

1. INSPECT INJECTOR INJECTION

CAUTION: Keep injector clean of sparks during the test.

- Remove the fuel inlet pipe from the fuel filter outlet.








- Connect SST (union and hose) to the fuel filter outlet with the 2 gaskets and union bolt.
SST 09268-41046 (90405-09015)

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





- Remove the fuel pressure regulator from the delivery pipe.
- Install the O-ring to the fuel inlet of pressure regulator.
- Connect SST (hose) to the fuel inlet of the pressure regulator with SST (union) and the 2 bolts.
SST 09268-41046 (09268-41091)
- Connect the fuel return hose to the fuel outlet of the pressure regulator.





- 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 09268-41046
- Put the injector into a graduated cylinder.

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

- Connect the TOYOTA hand-held tester to the DLC3.

(See on-vehicle inspection in fuel pump)





- 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: 69 - 88 cu.cm (4.2 - 5.4 cu.in.) per 15 seconds
Difference between each injector: 5 cu.cm (0.3 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 3 minutes

- Turn the ignition switch to LOOK.
- Disconnect the negative (-) terminal cable from the battery.
- Remove the SST and TOYOTA hand-held tester.
SST 0926841045
- Reinstall the fuel pressure regulator and fuel inlet pipe.
