Part Description
This engine control module (ECM) was removed from a 2003 Ford Taurus equipped with a 3.0L OHV engine and AX4S transmission. The unit carries ID marking 3F1A-KA and has been thoroughly inspected by our technicians. This brain box is currently on our shelf and ready for immediate shipment to get your vehicle back on the road.
The engine control module is the central computer that manages your vehicle’s engine performance, fuel injection, ignition timing, and emissions systems. ECM failures are common in older vehicles and can cause symptoms like rough idling, poor fuel economy, stalling, or complete no-start conditions. When your ECM fails, a quality used OEM replacement is often the most cost-effective solution compared to expensive dealer programming of new units.

This ECM is compatible with 2003 Ford Taurus models equipped with the 3.0L OHV engine and AX4S transmission. Contact us with your VIN to verify exact compatibility and programming requirements.
Does this engine control module need programming?
