摘要： A pressure sensor diagnostic system of the present disclosure includes an excitation module, a frequency determination module, and a fault determination module. The excitation module excites an in-cylinder pressure sensor and causes the in-cylinder pressure sensor to oscillate. The frequency determination module determines an oscillation frequency of the in-cylinder pressure sensor. The fault determination module diagnoses the in-cylinder pressure sensor based on the oscillation frequency.

摘要： A system for a vehicle includes a cylinder pressure sensor and a control module. The cylinder pressure sensor measures pressure within a cylinder of an engine, generates increases in a cylinder pressure signal based on the pressure, selectively generates a predetermined profile in the cylinder pressure signal, and selectively resets the cylinder pressure signal to a predetermined reset level after generating the predetermined profile in the cylinder pressure signal. The control module receives the cylinder pressure signal, detects the predetermined profile of the cylinder pressure signal, and detects the resetting of the cylinder pressure signal to the predetermined reset level when the predetermined profile is detected.
