Fuel Injector: Testing and Inspection

Fuel Injector Internal Components - Typical:

To perform a complete test of the fuel injectors and their circuitry, refer to DRB scan tool and appropriate Powertrain Diagnostics Procedures. To test the injector only, refer to the following:
Disconnect the fuel injector wire harness connector from the injector. Place an ohmmeter across the injector electrical terminals. Resistance reading should be approximately 12 ohms ± 1.2 ohms at 20° C (68° F).
