An internal combustion engine includes an electronic controller programmed to determine, for at least one combustion event in a combustion chamber, a theoretical polytropic constant, a measured polytropic constant, and a difference between the theoretical polytropic constant and the measured polytropic constant. The electronic controller is further programmed to calculate an adjusted pressure signal based on the pressure signal and the difference such that the adjusted pressure signal compensates for changes to an accuracy of the pressure sensor over time.
