The ECO mode in the 2006 Odyssey works by:
* Adjusting the throttle response: This makes the engine less responsive to acceleration, promoting smoother and more fuel-efficient driving.
* Altering the transmission shift points: The transmission shifts to higher gears sooner, reducing engine RPM and fuel consumption.
It's important to note that the 2006 Odyssey has a V6 engine which always runs on all six cylinders. The ECO mode does not deactivate any cylinders.
There are newer vehicles with cylinder deactivation technology, where the engine can switch between using all cylinders or only some of them depending on the driving conditions. However, the 2006 Odyssey does not have this feature.
