Part Description
This Engine Control Module (ECM) was removed from a 1994 Toyota 4Runner 4×4 equipped with a 6-cylinder engine, automatic transmission, and Federal emissions. The electronic brain box was located in the right-hand kick panel of the donor vehicle. This ECM has been inspected by our technicians and is currently on the shelf ready to ship.
The Engine Control Module is the central computer that manages your Toyota’s engine performance, controlling fuel injection, ignition timing, emissions systems, and transmission shifting. ECMs commonly fail due to electrical surges, corrosion from moisture exposure, or internal component degradation over time. When your ECM fails, you may experience poor fuel economy, rough idling, transmission shifting problems, or the vehicle may not start at all.
