Part Description
This engine control module was removed from a 2007 KIA RONDO equipped with a 2.7L engine and California emissions package. The ECM has been professionally inspected and is currently on our shelf ready for immediate shipment. This genuine OEM part carries manufacturer part number 39109-3E631 and is in working condition.
The engine control module is the central computer that manages your vehicle’s engine performance, fuel injection, ignition timing, and emissions systems. When an ECM fails, symptoms include poor fuel economy, rough idling, stalling, or complete engine shutdown. A faulty ECM often triggers multiple check engine lights and can leave your vehicle inoperable, making replacement critical for proper vehicle function.
