A control module comprising a cylinder torque determination module that
determines an indicated torque for a cylinder in an engine based on a
pressure in the cylinder, a cylinder torque balancing module that
determines a derivative term for the cylinder based on rotation of a
crankshaft, and a cylinder pressure error detection module that detects a
pressure error for the cylinder based on the indicated torque and the
derivative term. A method comprising determining an indicated torque for
a cylinder in an engine based on a pressure in the cylinder, determining
a derivative term for the cylinder based on rotation of a crankshaft, and
detecting a pressure error for the cylinder based on the indicated torque
and the derivative term.
