A method, system, and machine-readable storage medium for determining a predetermined operating condition of an internal combustion engine are disclosed. In operation, the method, system and machine-readable storage medium measure a cylinder pressure in at least one combustion chamber at a predetermined point in a combustion cycle. Next, the method, system, and machine-readable storage medium determine at least a first value for an operating parameter of the engine using the measured cylinder pressure, determine a second value for the operating parameter of the engine using data received from at least one engine sensor, and then generate a predetermined signal if a difference between the first value and the second value has a predetermined relationship. |
