Part Description
This Engine Control Module (ECM) was removed from a 2007 Nissan Versa sedan with 1.8L engine and automatic transmission (ID MEC90-411 A2 7426). The ECM was originally mounted on the left strut tower and has been professionally inspected by our technicians. This electronic control unit is currently on our shelf and ready to ship immediately.
The Engine Control Module is the brain of your vehicle’s engine management system, controlling fuel injection, ignition timing, emissions systems, and transmission operation. ECMs commonly fail due to electrical surges, water damage, or internal component degradation over time. When your ECM fails, you may experience no-start conditions, poor fuel economy, rough idle, or transmission shifting problems.
