Engine control role

The engine control module manages diesel combustion by processing sensor signals and commanding systems such as fuel injection and emissions controls. Its calibration determines how those controls respond to engine speed, load, temperature and other operating conditions.

The catalog filename Avensis 2.2D 2AD-FHV 89663-05763.bin identifies an engine application and calibration number, but it does not name a modified variant or a specific change made by this revision. The identifier should therefore be considered as a complete number when distinguishing it from other Toyota calibrations.
