Inconsistencies with Deceleration Fuel Cut Off - Toyota Yaris Forums

On my 09 AT liftback, DFCO is predictable. Any time I take my foot off the accelerator with the RPMs over 2500, I see DFCO mode. If I leave my foot off and let it coast, I see DFCO stop as soon as I drop below 1000 RPM.

The key though is the 2500 RPM or greater when you release the accelerator. If it is below that it will not kick into DFCO.

In my case, this is not true. Today I had DFCO kick in at 900 RPM one time. If DFCO is based on being above a certain RPM, my car doesn't follow the rule. Either way, I'm pretty sure DFCO works quite consistently at RPMs below 2500.
