IN-CYLINDER PRESSURE SENSOR DIAGNOSTIC SYSTEMS AND METHODS |
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.
