Checking operation sound
Using a stethoscope or long blade screwdriver, check the operation sound 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 PCM is suspected.
