Resistance/Operation Inspection

FUEL INJECTOR ON-VEHICLE INSPECTION





1. Remove V-Bank cover.
(a) Using a 5 mm hexagon wrench, remove the 2 cap nuts.
(b) Disconnect the 2 clips, and remove the V-bank cover.
2. Inspect injector operation.





Check operation sound from each injector.
(a) With the engine running or cranking, use a sound scope to check that there is normal operating noise in proportion to engine speed.
(b) If you have no sound scope, you can check the injector operating vibration with your finger.
If no sound or unusual sound is heard, check the wiring connector, injector or injection signal from the ECM.
3. Inspect injector resistance.
(a) Disconnect the injector connector.





(b) Using an ohmmeter, measure the resistance between the terminals.

Resistance: Approx. 13.8 Ohm at 2O°C (68°F)

If the resistance is not as specified, replace the injector.
(c) Reconnect the injector connector.
4. Reinstall V-Bank cover.

HINT: For fixing the V-bank cover, push on the cover until a "click" is felt.
