The PCM block controls tension of the operating oil valve. If the PCM block finds out that tension of management of the valve (calculated from the operating oil valve) – above or below the threshold tension (calculated from tension of a positive conclusion of the rechargeable battery), the PCM block decides that the chain of the operating oil valve is faulty.

The actual advancing of the moment of opening or closing of valves makes 30 ° from the target moment of opening or closing of valves at team of the maximum delay.

The actual excess of delay of the moment of opening or closing of valves makes 5 ° from the target moment of opening or closing of valves during 5 with when the control of the valve occurs within feedback range.
