Abstract:
A system and method for determining the oil pressure of an internal combustion engine is disclosed herein. The system and/or method may estimate the oil pressure using the response of two variable camshaft timing actuators having respective phase angle change control signals. Specifically, the signals may be used to determine whether the oil pressure is below a low oil pressure threshold value. The rate of response of the actuators may also be used to determine a current engine oil pressure.
