What is the typical resistance range for a common fuel injector coil?

The typical resistance range for a common fuel injector coil is generally between 10 to 16 ohms. Fuel injectors utilize electromagnetic coils to open and close the injector nozzle, and the resistance of these coils is a crucial parameter for their operation. This resistance range allows for sufficient current to flow through the coil when voltage is applied, enabling the injector to function effectively.

If the resistance is too low, it can indicate a short circuit within the coil, which can lead to excessive current draw and potentially damaging the injector or the vehicle's electrical system. Conversely, if the resistance is too high, it may suggest an open circuit or a faulty injector, which could prevent it from operating properly or delivering fuel as required. Thus, the well-established resistance range of 10 to 16 ohms serves as an essential benchmark for testing and diagnosing fuel injector health and performance.
