Part Description
This Engine Control Module (ECM) was removed from a 2005 Ford F-150 pickup truck equipped with the 5.4L V8 engine and automatic transmission. The part carries ID numbers 5L3A-CMB and 5L3A-12A650-CNB, confirming its compatibility with 4×4 F-150 models. Our technicians have inspected this ECM and it is currently on the shelf ready for immediate shipment.
The Engine Control Module is the brain of your Ford’s engine management system, controlling fuel injection, ignition timing, emissions systems, and transmission shift points. ECMs commonly fail due to electrical surges, moisture intrusion, or internal component degradation over time, causing symptoms like rough idle, poor fuel economy, transmission shifting issues, or complete no-start conditions. A functioning ECM is essential for proper engine operation and emissions compliance.
