Abstract
A method of monitoring an internal combustion engine by continuously computing pressure values of the cylinders from current parameters of the engines by using a mathematical model. At each point in time, there are both a computed pressure value and a measured pressure value, which are compared in order to provide information concerning the condition of a pressure sensor and to deactivate a faulty pressure sensor and use the computed pressure values for further operation of the engine.
