ABSTRACT:
A vacuum signal diagnostic system that diagnoses operation of a vacuum sensor of a brake booster system that is in fluid communication with an engine includes a first module that determines whether a vacuum signal of the vacuum sensor is increasing and a second module that compares an engine vacuum signal of the engine to the vacuum signal. A third module indicates a HI fault of the vacuum sensor when the vacuum sensor is increasing and a difference between the engine vacuum signal and the vacuum signal is greater than zero for a first threshold time.
