Fuel Injector: Testing and Inspection

FUEL INJECTOR TEST

Fig. 11 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 Diagnostic Procedure. 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).
