Injector Inspection Injection
CAUTION: Keep injector clear of sparks during the test.
Firstly disconnect the fuel inlet hose from the fuel tube.
This is done with specialized equipment but can be done in a simple situation as well.
You can remove all the injectors from the fuel rail and intake manifold so they can be tested individually.
If you have no LEXUS hand-held tester, connect the positive (+) and negative (-) leads from the battery to the fuel pump connector.
Injection volume: 60 – 73 Cu.cm (3.7 – 4.5 Cu.in.) per 15 Sec. Difference between each injector: 13 Cu.cm (0.6 Cu.in.) or less.
If the injection volume is not as specified, replace the injector or try and clean the injector to obtain the correct results.
In the condition above, disconnect the test probes of SST (wire) from the battery and check the fuel leakage from the injector. Fuel drop: One drop or less per minute
