WARNING: This page is about a different car, the 2004 Hyundai Santa Fe and 2003 Hyundai Santa Fe. However, it is still accessible from the selected car via links, so may be relevant.
The injectors inject fuel according to a signal coming from the PCM. The amount of fuel injected by the injectors is determined by the time during which the solenoid valve is energized. The amount of time the solenoid valve is energized is determined by the pulse width of the signal from the PCM.
