Part Description
This is a genuine OEM engine control module (ECM) removed from a 2005 Ford F-150 pickup truck equipped with the 5.4L V8 engine and automatic transmission. The ECM carries ID number 5L3A-CNB and has been thoroughly inspected to ensure proper functionality. This electronic control unit is currently on our shelf and ready to ship immediately.
The engine control module is the computer brain that manages your truck’s engine performance, fuel injection, ignition timing, and emissions systems. ECMs commonly fail due to electrical surges, water damage, or internal component degradation over time, causing symptoms like rough idle, poor fuel economy, stalling, or check engine lights. When your F-150’s ECM fails, a quality replacement is essential to restore proper engine operation.
