Injector Coil Resistance at Pamela Drake blog

Injector Coil Resistance. a resistance (ohms) check of the injector can identify a shorted coil. an injector has an electromagnetic coil, that when charged, pulls up on a pin which lets fuel into a cylinder. If you read zero resistance, the coil is shorted. Place a thin metal rod or screwdriver on one of the injectors and lean your ear close to listen for an audible clicking sound, which indicates the fuel injector is functioning.  — fuel injector resistance is the resistance to electrical current flow through the injector’s solenoid coil.  — injectors look the same but cannot be interchanged because of coil resistance, spray pattern, and flow rate. A resistance reading significantly higher or lower than the manufacturer's specification can indicate a faulty injector coil. Such a condition can lead to poor injector performance or complete failure. in this example the problem is high resistance in the injector coil winding which causes the opening and closing delay. If your reading is jumping all over the place, the coil is partially opened. Test each fuel injector in your vehicle the same way. This test should be done when the injector is cold as well.  — to test fuel injectors, start by popping your car's hood while the engine is running.  — interpreting results:  — if your meter reads infinite resistance, it means the coil in the injector is opened.
