Code is for crank sensor,but as stated,check for worn out plugs first..also check to make aure you dont have a dead coil on one of the cylinders....a misfiring or non firing plug will throw this code...if any of these need replaced,especiallynthe plugs USE OEM ONLY!!!.....if younso find it is the crank sensor,then change the crank and cam sensors togeather again USE OEM ONLY!!!!!
