Checking operation sound
Using a stethoscope or long blade screwdriver, check the operation sound ("tick-tick-tick") of injectors during idling or during cranking.
Check that as the engine speed increases, the frequency of the operating sound also increases.
Caution: Note that even if the injector you are checking is not operating, you will hear the operating sound of the other injectors.
NOTE: If no operating sound is heard from the injector that is being checked, check the injector drive circuit. If there is nothing wrong with the
circuit, a defective injector or ECM is suspected.
