It is a message from the PCM that some sensor(s) or operating parameters arn't reporting correct information to the PCM or the sensor are providing information that is causing the PCM to protect the powertrain. The problems that can cause a reduced engine power are probably too numerous to list.

Well a loss of power could be caused by a lot of things. Start by checking the computer for trouble codes to see if that gives you a idea of where to start. It might just be a malfunctioning sensor. Without knowing the engines history I can't say if it could be a more serious type of trouble.
