My civic's check engine light came on last night while racing a Ford Lightning, i tapped rev limited at the top of 4th and thats when it came on and still hasn't went off. Im thinking since the car jerked a lil when i hit rev limiter that it may a jard a sensor loose or something? I went wire hunting today for it, but couldnt find anything. Car is still running perfect , no idling problems, or accerlation problems.. lights just on. Any suggestions might be helpful, thanks

Car has 96,xxx miles on, ugh intake and exhuast if that might help at all?
