Injection volume:
111 - 141 cm
3 (6.8 - 8.6 cu in.) per 15 sec.
Difference between each injector:
10 cm
3 (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 tester probes of
SST (wire) from the battery and check the fuel leakage
from the injector.
