DIAGNOSTIC SYSTEM AND METHOD FOR DETECTING INTERNAL COMBUSTION ENGINE FAULTS USING EXHAUST PRESSURE READINGS

A diagnostic system and method that (a) that uses models indicative of both successful firing and skips to determine if cylinders of a skip fire controlled internal combustion engine have successfully fired or successfully skipped and (b) uses filtered exhaust gas pressure readings for detecting fau...
