have you just tried pulling the ground off the battery and leaving it for half an hour? i have heard that it sometimes works, my check engine light came on because of a bad ignition coil (I MEAN IT WAS BAD) so i cleaned up the grounds and it worked but the light was still on....i just unplugged the battery and it was all back to normal!
