Hyundai Genesis (DH): Engine Control System / Injector Description and Operation

Hyundai Genesis (DH) 2013-2016 Service Manual / Engine Control / Fuel System / Engine Control System / 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 reach the peak, and then settle at system voltage.

    Inspection 1. Connect the GDS on the Data Link Connector (DLC ). 2. Measure the output voltage of the FTPS. Specification: Refer to "Specification" Removal 1.
