89663-05G51 is a Toyota engine control calibration listed for the Avensis ZRT-272 with the 2.0-liter 3ZR-FAE engine and continuously variable transmission (CVT).

Engine and CVT application
The 3ZR-FAE uses Toyota’s Valvematic variable valve lift system. Engine management coordinates valve operation with other controls to meet the driver’s power demand while managing fuel consumption and emissions. In a CVT-equipped vehicle, engine and transmission controls also work together to deliver the requested acceleration.
