The throttle calibration works perfectly, TPS values ​​are normal with no fluctuations, but there’s no response when I press the gas pedal.

dbw calibration has been performed, there is no imbalance in the voltages, tps calibration has been performed, there is no problem with the voltages, but there is no reaction when I press the gas, even though it is buzzing from the dbw. When I press the gas pedal, although the gas position changes between 0-100, there is no change in DBW.

It’ll never move if you don’t tell it to. The table shown is the pedal to blade command, its all zero, which would be zero movement.

Absolutely correct observation, thank you very much. I hadn’t noticed; I remembered it being generated automatically.
