Fuel Injector: Testing and Inspection
Operation Sound Check
INJECTOR INSPECTION
OPERATION CHECK
Using a HI-SCAN:
-
Activate the fuel injectors in sequence.
-
Check the operating time of the injectors.
OPERATION SOUND CHECK
1. Using a stethoscope, check the injectors for a clicking sound at idle. Check that the sound is produced at shorter intervals as the engine speed
increases.
NOTE: Ensure that the sound from an adjacent injector is not being transmitted along the delivery pipe to an inoperative injector.
2. If a stethoscope is not available, check the injector operation with your finger.
If no vibrations are fell, check the wiring connector, injector, or injection signal from ECM.
RESISTANCE MEASUREMENT BETWEEN TERMINALS
1. Disconnect the connector at the injector and measure the resistance between the two terminals.
Standard value: 15.9 ± 0.35 Ohms at 20 °C (68 °F)
2. Re-connect the connector to the injector.
