Kia Sorento: Injector Description and Operation
Kia Sorento (MQ4, 2021-2026) Service Manual / Engine Control / Fuel System / Fuel Delivery System / Injector Description and Operation
| Description |
| • |
Based on information from various sensors, the Engine Control Module (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.
