The fuel injector coil is made up of a wire coil that is wrapped around a metal core. When an electrical current is passed through the coil, it creates a magnetic field that pulls the core upward. This upward movement of the core opens the fuel injector valve, allowing fuel to flow into the combustion chamber.
When the electrical current is turned off, the magnetic field collapses and the core moves back down, closing the fuel injector valve. This stops the flow of fuel into the combustion chamber.
The fuel injector coil is an important part of the fuel injection system, and it must be functioning properly in order for the engine to run properly. If the fuel injector coil is not working properly, it can cause the engine to run too lean or too rich, which can lead to a variety of problems, including:
* Engine misfires
* Loss of power
* Increased fuel consumption
* Rough idling
* Check engine light
