Part Description

The module carries part number 12600473 and has been thoroughly inspected by our technicians. This genuine OEM component is currently on our shelf and ready for immediate shipment.
The Engine Control Module is the central computer that manages your vehicle’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, check engine lights, or no-start conditions. When your ECM fails, a quality replacement is essential to restore proper engine operation.
