Low oil itself will not cause a check engine light however, if the oil is low enough it will cause problems with the variable valve timing. That can result in noise and misfiring that could bring a check engine light. This usually occurs when the oil is 3-4 quarts low, from what I have seen. The should not use oil quickly, 1 quart in 2000 miles is considered normal.
