Abstract
A method of indicating a fault associated with a non-combustion chamber of an engine includes monitoring a fluid intake pressure for the engine, monitoring a pressure for a non-combustion chamber of the engine, and indicating a fault associated with the non-combustion chamber based on a difference between a first non-combustion chamber pressure and a second non-combustion chamber pressure being below a chamber threshold value.
