(Clamp) (i) Put the injector into a graduated cylinder.
CAUTION:
Vinyl Tube Install a suitable vinyl tube onto the injector to prevent gas-
A23216 oline from splashing out.
(j) Operate the fuel pump (see page SF-5).

SFI (1GR-FE) - INJECTOR
(k) Connect the SST (wire) to the injector and battery for 15
seconds, and measure the injection volume with a gra-
duated cylinder. Test each injector 2 or 3 times.
SST 09842-30080
SST
Volume: 76 to 91 cm3 (4.6 to 5.5 cu in.) per 15 seconds
(Wire)
Difference between each injector:
Connect 15 cm3 (0.9 cu in.) or less
If the injection volume is not as specified, replace the injector.

2. INSPECT LEAKAGE
Under the above conditions, disconnect the tester probes of the
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
