PCM software update to correct fause oxygen sensor code on Hyundai XG300

If the Check Engine Light illuminates, indicating a problem with the front oxygen sensor, but the sensor tests okay, reprogramming the engine's control computer should fix the problem. Then, the Check Engine Light will no longer falsely illuminate and the acceleration, particularly from a stopped position, will be smoother.
