Part Description
This used OEM engine control module was removed from a 2016 Hyundai Elantra equipped with a 1.8L engine and automatic transmission. The ECM has been professionally inspected by our technicians and is currently on the shelf ready for immediate shipment. This genuine Hyundai part carries ID number 391012EMK6 and was designed for California emissions compliance on US-built vehicles.
The engine control module serves as the brain of your vehicle’s engine management system, controlling fuel injection, ignition timing, emissions systems, and transmission operation. ECM failures commonly occur due to electrical surges, water damage, or internal component degradation over time, resulting in symptoms like rough idling, poor fuel economy, transmission shifting issues, or complete engine shutdown. When your ECM fails, replacement with a quality used OEM unit is often the most cost-effective repair solution.
