What the engine controller does
The engine control module manages engine operation using sensor inputs to determine functions such as fuel delivery and ignition timing. In a 1ZR-FAE application, engine management also coordinates the engine’s variable valve systems. These controls affect starting, drivability, fuel consumption and emissions.
Those are general functions of the engine controller, not documented changes introduced by calibration 89663-0F311. The available catalog names do not identify a specific drivability fix or modified feature.
