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).
