What the engine controller does
The engine control module manages the 2AR-FE’s operation using sensor inputs and programmed calibrations. Its responsibilities include controlling fuel injection, ignition timing and electronic throttle response, as well as coordinating variable valve timing and emissions-related functions. These controls affect how the engine starts, idles, responds to the accelerator and operates across different driving conditions.
