39110-3C765/ 391103C765 / 28153095 Engine Control Module (ECM) Hyundai Sonata 3.3L 2009-2010.

Product Description

The Engine Control Module (ECM / ECU) bearing part numbers 39110-3C765 (also referenced as 391103C765 or 28153095) is a genuine OEM control unit used in Hyundai Sonata models equipped with the 3.3L V6 engine, especially in model years 2009-2010. This unit is responsible for managing critical engine functions such as fuel injection, ignition timing, sensor monitoring, emission systems, idle control, and diagnostics (OBD).

Prior to installation, the unit should be verified for correct part number, software version, connector pinout, and compatibility with the vehicle’s VIN and immobilizer system. In many cases, programming or adaptation / re-flashing will be required to match the replacement module to the specific vehicle.

The module is typically offered in used, remanufactured, or refurbished condition. It is tested for electrical and logic functionality before shipping, but due to the sensitive nature of control modules, buyers should ensure return policies and test capabilities are available.
