Hyundai Sonata: Injector. Description and Operation
Description
Based on information from various sensors, the ECM can calculate the fuel
amount to be injected. The fuel injector is a solenoid-operated valve and the
fuel injection amount is controlled by length of injection time. The ECM controls
each injector by grounding the control circuit. When the ECM energizes the injector
by grounding the control circuit, the circuit voltage should be low (theoretically
0V) and the fuel is injected. When the ECM de-energizes the injector by opening
control circuit, the fuel injector is closed and circuit voltage should momentarily
peak, and then settle at system voltage.
