An electronic arrangement for controlling gas exchange valves of an internal combustion engine with variable valve control is presented. The valve control makes possible to completely hold closed at least the inlet valves and the electronic arrangement is equipped with means for detecting the air quantity, which is inducted by the engine, and with means for detecting the valve stroke. The electronic control arrangement changes the opening function in overrun operation starting from the fully closed inlet valves so that an opening of the inlet valves takes place and the arrangement detects the index of the valve opening at which a reaction of the air quantity detection takes place and uses this index as a reference point for determining the actual opening cross section.
