ON-VEHICLE INSPECTION

1. REMOVE SUSPENSION UPPER BRACE

2. REMOVE NO. 2 CYLINDER HEAD COVER

3. INSPECT INJECTOR OPERATION
Check the operation sound of each injector.




1. With the engine running or cranking, use a sound scope to check that there is normal operating noise in proportion to the engine speed.
2. 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.

4. INSPECT INJECTOR RESISTANCE




a. Disconnect the injector connector.
b. Using an ohmmeter, measure the resistance between the terminals.

Resistance: 13.4 - 14.2 Ohms at 20°C (68°F)

If the resistance is not as specified, replace the injector.

c. Reconnect the injector connector.

5. REINSTALL NO. 2 CYLINDER HEAD COVER
